[Guide] Install Windows 8 UEFI on Legacy BIOS with Clover (and Dual boot with Yosemite)

99 posts in this topic

Recommended Posts

Hi ,

Since windows 7 can't recognize SATA hard drive, I am trying Windows 8.1

I have install.wim more Than 4GB, So I split it with OS x split command in terminal and now I have in the usb drive 2 files install.wimaa and install.wimab

do I need to merge them?

 

Edit: Ok I solved the split problem simply it worked with 2 split files.

But Unfortunatly even Windows 8.1 doesn't recognize SATA drives :-(

@carlocav,

Have you tried "cleaning" your Windows hard drive with Diskpart.exe?
1. Boot your computer with the UEFI Windows Installer USB
2. Go to the command prompt by pressing Shift + F10 at the first GUI screen
3. Type the following commands followed be <Enter> after each line

Diskpart
list disk

Hopefully diskpart will be able to see and list your "invisible" drive eg
clip_image002_thumb%25255B1%25255D.jpg?i
select disk X (where X is the disk number of the target Windows hard drive)
In this example, it’s Disk 1
Select Disk 1
Type Clean to clean any present partitions
Type Convert GPT to convert the disk to GPT partition table
Now we are going to create the EFI partition:
Type create partition EFI size=200
Type: format quick fs=fat32 label=EFI

Now we need to create the OS partition which will take the rest of the space available
Type: create partition primary
Type: format fs=ntfs quick label=Windows

4. Exit from command prompt, restart the computer and see if the UEFI Windows installer can now see your drive....
__________________________________________________________________________________________________________

If all else fails and you can only install Windows in legacy mode, a workaround is to give the legacy Windows boot loader first priority in the BIOS and chainload to Clover on the second hard drive when you need OSX.

  • When you want Windows, its own bootloader will boot Windows on the first hard drive
  • When you want OSX, you can select Clover from the Windows Boot Manager ---> chainloads to Clover on the second (GPT) hard drive and loads OSX

Thank you

It doesn't work but disk part recognize the hard drive and I managed to follow your procedure, and even the BIOS recognize the drive. So, if Disk Part see the drive why not the Windows installation?

Creating Installation Media:

We will prepare a single USB drive which can be used to install Yosemite, Windows (and even Ubuntu if you fancy!).

 

 

Just wanted to share a few tips on installing Linux Mint 17.1 in UEFI mode for a triple boot :).

 

1.  Leave 30-60GB of free space for the install

2.  Download the x64 linux iso version from here

3.  Boot with Clover into the UEFI linux media (DVD or USB)

         a.  Make sure that VBoxExt4-64.efi is installed in /EFI/CLOVER/drivers64

         b.  If you want to install via a Linux Mint DVD, install GrubUDF-64.efi and VBoxIso9600-64.efi in /EFI/CLOVER/drivers64

              Choose “Boot UEFI optical from CDROM” at the Clover Main Menu....

post-846696-0-14451000-1426026125_thumb.png

         c.  If you want to install via a UEFI USB installer, make sure it is formatted to FAT32 and copy the entire contents of the iso to it.  I did this in Windows with 7zip...

post-846696-0-55510800-1426026160_thumb.png

              Create a folder eg “linuxmint” or “ubuntu” in the /EFI folder of the USB installer and copy the grubx64.efi file to it (from /EFI/boot). 

post-846696-0-98637100-1426026227_thumb.png

              Choose “Linux Mint EFI boot menu” or “Ubuntu EFI boot menu” (depending on how you named the folder above) at the Clover Main Menu to start the installer...

post-846696-0-72095900-1426028031_thumb.png

4. Follow this procedure to install Mint 17.  Note:

       a.  Format with GParted

                /          Ext4    10-20GB

               Home    Ext4    18-36GB

               Swap    swap    2-4GB

       b.  make sure to install the GRUB bootloader into the EFI partition

 

5.  After the installation has completed, reboot the computer with Clover...you will see 2 entries.  Both will boot into linux Mint....

Boot Ubuntu EFI boot menu from EFI ---> runs grubx64.efi to launch Mint

post-846696-0-54416500-1426026518_thumb.png

Boot vmlinuz from xxxx (Ext 4 / partition name) --->  runs the linux kernel directly to launch Mint

post-846696-0-44258400-1426026569_thumb.png

 

 

Don't know why at the part of windows and yosemite installer, you format the USB as GPT ? MBR format on the USB can boot Windows UEFI installer just fine ( of course FAT32 partition ). If so then you must create another FAT32 partition for Clover ( the Test Clover Config section at the beginning ). Different method, same result

That’s a valid point since some machines with legacy BIOS won’t boot from a USB if it is GPT formatted (this doesn’t affect booting from GPT hard drives in those systems though).

 

In summary, to create a multi-boot Clover MBR installer USB, @avin7000’s procedure needs a few modifications:

 

1.    In Disk Utility, create an extra 200MB FAT32 partition.  In the screenshot below, I’ve named this CLOVER.

 

post-846696-0-37387500-1425944134_thumb.png

       a. Choose 4 Partition Layout with 5GB FAT32 for WIN, 3GB FAT32 for LINUX, 8GB HFS+ for OSX (if using a 16GB or larger USB).

       b. Under “Options”, choose MBR format, then apply changes.

       c. Unmount, then format the 200MB CLOVER partition to FAT32 using terminal:

diskutil list
diskutil unmount /dev/diskXs1 (where X=disk number of USB)
sudo newfs_msdos -v CLOVER -F 32 /dev/rdiskXs1 

2.  Copy the Windows and Linux install files from DVD or mounted ISO into the respective FAT32 partitions.  Note in the files from the Linux Mint iso, there is a hidden folder named ".disk" that needs to be copied across, so I enabled "show all files" in Finder.

 

       a. Enable showing of hidden files in Finder by typing in terminal

 defaults write com.apple.finder AppleShowAllFiles -boolean true ; killall Finder

       b. For Windows, make sure bootmgfw.efi is copied to /efi/Microsoft/boot and rename cdboot.efi to cdboot.bak

post-846696-0-16700500-1426025785_thumb.png

Notes:  For Windows 8 and 10, copy bootx64.efi in the efi/boot folder to efi/microsoft/boot and rename it bootmgfw.efi.

   For Windows 7, extract bootmgfw.efi from the "install.wim" using 7-Zip (open the iso and navigate to sources/install.wim/1/Windows/Boot/EFI/bootmgfw.efi) and copy to efi/microsoft/boot.

 

       c. For Linux, make sure to create a folder inside the /efi folder for the bootloader eg “ubuntu” or “linuxmint” and copy grubx64.efi into it.

post-846696-0-55131600-1426025831_thumb.png

 

3.  For the OSX partition, use the createinstallmedia method (ensure OS X installer app is in /Applications folder).

 

sudo /Applications/Install\ OS\ X\ Yosemite.app/Contents/Resources/createinstallmedia --volume /Volumes/OSX --applicationpath /Applications/Install\ OS\ X\ Yosemite.app

4.  Install Clover targeting the “CLOVER” partition instead of the EFI partition.

 

post-846696-0-32644800-1425944297_thumb.png

       a. I use the following custom install options...

 

post-846696-0-33877800-1425944317_thumb.png

 

       b. Copy the config.plist, DSDT/SSDT.aml file(s) which are specific to your system into the Clover folder:

           - Put config.plist in /EFI/CLOVER directory

           - Put DSDT.aml in /EFI/CLOVER/ACPI/patched

           - Put FakeSMC.kext and other kexts required in EFI/CLOVER/kexts/10.x (where x is your version of OSX)

 

5.  Boot from the USB and you should see the following options at the Clover Main Menu:

 

post-846696-0-45181100-1425944355_thumb.png

“Boot Microsoft EFI boot menu from WIN” ---> boots Windows installer via bootmgfw.efi

“Boot Linux Mint EFI boot menu from LINUX” ---> boots Linux installer via grubx64.efi

“Boot OS X Install from Install OS X …” ---> boots OSX installer via boot.efi

thanks fusion :)

The only downside I noticed (for me only, maybe it doesn't happen to others) that it takes hella time to load, and when I update the kernel, Clover see all the kernels (eventho I configured it to show only the latest), and the sound breaks for me (ALC275) on linux when booting either Clover > Kernel or Clover > Grub > kernel, I donno why, but it's like that, anyway, I found a workaround, and there was an update from the linux comunity for the driver afterward, I managed to make Grub2 my main bootlaoder, and making it boot Clover (it's all UEFI, no legacy). This just some results of testing, not actually anything to help this guide :)

@midi,

 

Yeah, you will see multiple entries if you install new kernels without deleting the old ones. 

 

If you remove VBoxExt4-64.efi from /EFI/CLOVER/drivers64, this will effectively hide the linux kernel entries from Clover's Main Menu but leave the grubx64.efi entry to boot into the linux installation.  Alternatively, you can try hiding the grub entry in your Clover config.plist, (GUI Section) leaving the vmlinuz kernel entry(s) to boot from eg

		<key>Hide</key>
		<array>
			<string>grubx64.efi</string>
		</array>

I haven't personally noticed any slow booting/loading issues or sound problems on my legacy desktop rig (GA-P55aUD3/i5-750/ATI HD5770), triple booting UEFI Windows 10 X64, OSX Yosemite 10.2 and Linux Mint  17.1.  In fact just about everything works very well OOTB with Mint 17.1 on my rig :D.

Good for you :P As you have a desktop, you wouldn't have those laptop problems :D anyway, I use Grub2 as my main bootlaoder for some reasons:

- No audio issues anymore :)

- Booting Android (4.4 and 5.0alpha)

- Windows booting fine without the trackpad issue I find on Clover (I can't use the trackpad until windows is loaded ad logged in and I still have to wait for Syaptics drivers to load)

- I made a Clover menuentry and configured clover to timeout=0, looks like Grub2 booting OS X automatically :D

 

Hope Clover v3 fix all those!

I'm using an optiplex 745 and cannot get the windows installation to boot through clover.  I've tried all methods.  I  did this:

 

1.  Rename cdboot.efi in WIN81/efi/microsoft/boot folder to cdboot.BAK

2.  Copy bootmgfw.efi into WIN81/efi/microsoft/boot

 

However, I couldn't even find the bootmgfw.efi on my .iso (is it supposed to be there?), so I took it from my windows installation on my windows 8 tablet.  This showed up fine:

 

Select "Run bootmgfw.efi" and then press <spacebar> ---> should now boot into the UEFI Windows Installer!

 

But all it does is boot to a black screen, or it will show a strange small error box with alternating black and yellow bars going diaganally.

 

I also tried the rufus method, but when booting from that drive, once again is shows the black and yellow lines in a box.  I know for a fact that the .iso works fine as I've used it to install windows by itself.

 

 

EDIT:  I got it to boot into the windows installation.  I was confused about extracting the bootmgfw.efi from the .iso, but finally understood.  The problem I have now is that It just goes straight from showing the windows icon to saying recovery, 'your computer must be repaired' or something along those lines.  Does anyone know what the issue is?

 

EDIT 2:  I formated my windows install usb to MBR. And it boots into installation.  I'll try installing it to my set aside windows partition on my main HD, but I don't know if it will work.  I'm just really confused at this point.

In Windows 7, you can extract bootmgfw.efi from the "install.wim" using 7-Zip (open the iso and navigate to sources/install.wim/1/Windows/Boot/EFI/bootmgfw.efi).

 

For Windows 8 and 10, you can extract bootx64.efi from the iso using 7-Zip (in the /efi/boot folder) ---> copy to efi/microsoft/boot folder on your UEFI Windows installer USB and rename it bootmgfw.efi.

For the actual installation on your hard disk, it is best to just leave free space on the drive and the Windows installer will automatically create the necessary partitions (including the Microsoft Reserved Partition)...there can be issues if you add a FAT partition for Windows on the hard drive using OSX Disk Utility since it automatically converts the GPT disk to hybrid MBR ---> Windows thinks it is an MBR disk (see post#359)!

Thank you.  Yes I figured out that I need to keep it as free space and not format it as FAT before installing windows.  I was initially doing this all with 2 flash drives and wanted to make into one, but I having troubling get the USB to boot with both the OSX and windows partitioned formatted as MBR.  Then I followed your multi-boot clover MBR install USB post and got it all working fine on a single usb.  Thanks!

you can copy and rename bootx64.efi in /efi/boot to /efi/microsoft/boot after You extract windows iso on USB Fat32. I usually do that.

Hello everyone,

ive got a Problem at booting the win8/10 Installation. It always ends in the fail oxc000000e.

Ive done everything in the guide. The only thing that can i install is the win10 Installation created with Bootcamp.

Thanks in advance!

@WeWin,

 

Most likely you have a GPT disk with hybrid MBR instead of pure GPT (with protective MBR).  This often happens when you use Disk Utility or Apple's Bootcamp utility to prepare a FAT partition for Windows (it always assumes you want to install legacy MBR Windows).

 

Check your GPT layout with GPT FDisk/"GDisk".

 

Instructions for restoring the protective MBR in post#359.

 

For the actual installation of UEFI Windows on your hard disk, it is best to just leave free space on the drive and the Windows installer will automatically create the necessary partitions (including the Microsoft Reserved Partition).

Thank you for your fast answer.

Gdisk gives me this output:

Partition table scan:
  MBR: protective
  BSD: not present
  APM: not present
  GPT: present

Found valid GPT with protective MBR; using GPT.

And with the Argument p it says:

Partition table holds up to 128 entries
First usable sector is 34, last usable sector is 250069646
Partitions will be aligned on 8-sector boundaries
Total free space is 69632437 sectors (33.2 GiB)

Number  Start (sector)    End (sector)  Size       Code  Name
   1              40          409639   200.0 MiB   EF00  EFI System Partition
   2          409640       107831519   51.2 GiB    AF00  Yosemite_I
   3       107833344       108095487   128.0 MiB   0C01  Microsoft reserved ...
   4       108095488       180439039   34.5 GiB    0700  Basic data partition

It says that i have GPT i think because i can hold up to 128 entries and ive got the MBR protective for Windows that I want.



Ive followed the guide in the first post. Let free space for windows and windows will format it himself. 
But i cant boot with the original Windows installations created with the Windows 7 USB tool (windows 8/10 original ISOs from Windows)

 

Sorry for my english, its not my native language.

@WeWin,

 

I would recommend manually creating a UEFI Windows installer as I describe in post#29 rather than the Windows 7 USB tool. 

 

Transfer all the Windows install files from DVD/iso image to a FAT32 (not NTFS) partition on the USB.

 

The results from GDisk look good - the target hard disk is pure GPT with protective MBR so the problem lies with how you created your installer (USB should be formatted FAT32, can be MBR or GPT but not hybrid MBR).

@fusion71au,

 

Thanks i will test and report. Should the partition table be MBR or GPT?

I will test it with GPT and report back!

 

Edit:
Its not working. Im now installing it over the Bootcamp created Installer and  so it works :)

Big thanks to avin7000 and fusion71au! 

Yosemite and Windows 8.1 Update 3 are fully working here. 

When installing Yosemite, I can't create two partitions but leaving 2nd partition "free". So I created two HFS+ partitions and then deleted the 2nd one, making it free to Windows installer.

Thanks again fusion71au, it works like a charm on an old legacy bios Dell D830 laptop. Now have a Yos/El Capitan/Win8.1/Mint 17.1 full UEFI quad boot :thumbsup_anim:

 

But I ran into one problem and hope you could help :

 

If I try to check/repair Windows c: partition using chkdsk :c /F, I'm almost certain to have a 0xC000000E error (not sure that's the correct number but it's a BOSD) when it boots the second time and when the check/repair process reaches 100%.

 

Only solution is to actualize Windows which is a pain in the a**ss :angry:.

 

My guess is that it has something to do with the fact that it's not a true UEFI setup and in some way, it fails to find the windows boot manager…

 

Of course, one obvious workaround is to avoid to use chkdsk on the c drive (other NTFS partitions checks/repairs fine) but that's a little bit annoying :P.

@Polyzargone,

 

I haven't tried running chkdsk /f on my C Drive or EFI partition but I wouldn't be surprised if Windows 8/10 tries to remove Clover's boot0 from the bootsector when you do this.

 

eg for Windows 10 insider previews, each major version upgrade through Windows Update (as opposed to a clean install) overwrites the bootsector so legacy Clover needs to be re-installed.  Windows doesn't like it when it finds its bootloader is not in charge :P.

 

Some troubleshooting: 

Is Windows hybrid boot turned on? 

What does the chkdsk log say?

You can see the exact bluescreen error by running the BlueScreenView tool.

Thank you for that very interesting information :). I'll read that carefully !

 

I didn't install Win10 TP yet and probably won't until the final release (at least on the D830) but as you can see on the attached picture, OS X Yos isn't on the same drive that Win 8.1 (El Capitan partition wasn't installed when I ran into that problem and disk1s8 & disk1s9 are actually Mint's ExFat4 & Swap partition).

 

I thought it shouldn't mess up with Clover since the bootmgfw.efi is in it's own "NO NAME" EFI partition, along with Mint's grubx64.efi. And I didn't have to reinstall Clover after that damn BOSD BTW.

 

But reading your post for Windows 10 insider previews install, I realize that I didn't installed Win 8.1 that way.

 

In short I have :

 

• Created an MBR Clover 2 Gb USB pen.

• Disconnected OS X SSD

• Booted on Clover USB pen

• Selected UEFI Windows installer DVD from Clover boot menu

• Proceeded of Win8 install on a blank drive

• Booted on Clover USB pen and selected "Boot Microsoft EFI from EFI" to finish install.

• Made all necessary Win8 updates and booted on USB at each reboot

• Reconnected OS X SSD and set it as first boot device in bios so Clover can boot both OS X & Win8

 

For the other OS, I won't give more details but you got the idea :D.

 

So maybe that not renaming bootmanagers and replacing them with Clover's one could explain why I didn't have to reinstall it ?

So I'm booting with legacy clover with a legacy bios non UEFI and I'm trying to dual boot with yosemite and windows 10 but I had to make flash drive with Rufus then transfer the efi or what not under the troubleshooting guide but when I click on my partition I made for windows though disk utility as free space. So on windows I click the unallocated space partition and click next which then it says " windows cannot prepair the computer to boot into the next phase of installation. To install windows, restart the installation

Well why I'm at it is it possible to get clover to boot legacy windows because all I got was a white square that's why I started to try this

      Install macOS 10.15 Catalina on Gigabyte P55-USB3 with Radeon RX 580 graphics card using a USB device created with the createinstallmedia command and Clover as bootloader. Instructions to install macOS 10.14 Mojave on this computer are almost identical, replacing Catalina app with Mojave, so this article is suitable for both versions of macOS. The Gigabyte P55-USB3 motherboard (and some others from the same brand with the P55 / H55 chipset) have made it easy to build a hackintosh and install macOS since 10 years ago. Although it is an old motherboard, the behavior with Mojave or Catalina is very good after changing the classic hard drive (HDD) for a solid state drive (SSD).

      Components of the hackintosh
      Gigabyte GA-P55-USB3 motherboard: P55 chipset, 1156 socket, ALC892 audio, Gigabit RTL8111D network, DDR3 RAM Intel Core i5-750 processor for socket 1156: 4 cores, 8MB cache, clock rate 2.66 GHz Fenvi FV-T919 wireless + Bluetooth card: PCI-Express, wifi is ac type, detected by macOS as Airport and Apple Bluetooth Radeon RX 580 8 GB graphics card: works OOB but with a few details to be considered, it has its own article.  
      Previous requirements
      Install macOS Catalina app in /Applications folder USB flash drive with at least 16GB prepared from Disk Utility with MBR partition scheme and formatted as Mac Os Plus (on older Gigabyte boards like mine, USB sticks partitioned with GUID scheme instead of MBR usually hang the system when booting) Recent version of Clover (I have used r5117) Recent versions of Lilu (at least 1.4.4) and WhateverGreen (at least 1.3.9) to fine-tune the behavior of the graphics card Recent version of RealtekRTL8111 (I have used 2.2.2) FaceSMC version 6.26-322 (newer versions disable automatic mounting of USB devices on my system).  
      Create install USB
      Run this command from Terminal (assuming the target device is called USB):
      Bash: sudo /Applications/Install\ macOS\ Catalina.app/Contents/Resources/createinstallmedia --volume /Volumes/USB /Applications/Install\ macOS\ Catalina.app
      Clover must be installed on the USB memory, I choose the following options:
      Bootloader > Install boot0af on the MBR CloverEFi > CloverEFI 64-bit SATA BIOS Drivers, 64 bit > Recommended drivers > FSInject + SMCHelper + XhciDxe BIOS Drivers, 64 bit > File System drivers > ApfsDriverLoader Install RC scripts on selected volume Optional RC scripts > Disable sleep proxy client.  
      You have to copy 4 kexts to the EFI/CLOVER/kexts/Other folder of the USB device: FaceSMC 6.26-322, Lilu 1.4.4, WhateverGreen 1.3.9 and RealtekRTL8111 2.2.2. Regarding the config.plist file, the most significant is:

      Install macOS Catalina

      Boot from the USB device and choose Install macOS from Install macOS Catalina. The installation program runs until the PC restarts. Here choose Install macOS from HDD (the name of the volume you are installing macOS on). With RX 580 graphics card, the screen goes black in this second phase of the installation, it is a phase in which the user has nothing to do until the PC is restarted so you can let it work until the Clover menu again. You have to choose Boot macOS from HDDto boot the installed system from the hard disk, the screen is recovered and you can configure the account and the initial options. From this moment the screen works fine.

      In summary:
      Boot from USB > Clover menu > Install macOS from Install macOS Catalina > screen works fine Boot from USB > Clover menu > Install macOS from HDD > black screen Boot from USB > Clover menu > Boot macOS from HDD > screen works fine.  
      Install Clover and kexts on the hard drive

      Clover needs to be installed on the disk where we just installed macOS. Options are the same as when installing it on the USB memory. You also have to copy the 4 kexts (FaceSMC 6.26-322, Lilu 1.4.4, WhateverGreen 1.3.9 and RealtekRTL8111 2.2.2) into the EFI/CLOVER/kexts/Other folder on the EFI partition of the disk. And review the config.plist file remembering the comments for the USB.

      If everything goes well, the computer starts from the hard disk with a running copy of macOS Catalina.

      Radeon RX 580 8 GB graphics card on macOS High Sierra (as of 10.13.6), Mojave and Catalina on the P55-USB3 board: excellent performance with acceleration (Metal) OOB, no need for drivers (kexts), with 3 drawbacks, one has to do with the boot of the operating system (a solution is proposed), another with the number of rear connectors enabled (a solution is proposed) and another that only affects to one phase of the Mojave or Catalina installation (without clear solution for now).

      I have placed the XFX AMD Radeon RX-580 P8DFD6 8GB Triple X Edition GDDR5, 256BIT, DVI + HDMI + 3DP graphics card on a 10 year old motherboard (Gigabyte P55-USB3) in order to update the hackintosh to 10.14 Mojave and 10.15 Catalina because the card that I have used in past years, Nvidia Geforce GTX 750 1GB, has stopped working after 10.13.6 High Sierra since this was the last version for which Nvidia published the alternate web drivers that were necessary for the card to work well with graphic acceleration.

      The new RX 580 card needs considerably more space than the old one although it fits perfectly in an ATX case, and requires an additional power connector. It has 2 big fans that most of the time are stopped, at least in my case. In macOS it works perfectly, even with Metal acceleration, without additional drivers and without extra settings in Clover. But it has drawbacks that I comment below.

      Alterations during startup

      During the boot of the operating system, when the screen goes from the basic driver to the AMD driver, 2 artifacts appear randomly, they are very short in duration (from one to a few seconds):
      Very short flashing white screen that may or may not be accompanied by purple lines The fans runs for a few seconds (the noise is clearly audible). This behavior is solved with the installation of 2 kexts, Lilu and WhateverGreen. Lilu is an extension created by acidantheraand vit9696 among others whose function is to help to patch kexts, processes and libraries during macOS boot. It is accompanied by specific plugins for the task required, for example WhateverGreen that injects necessary patches for certain AMD, Intel and Nvidia graphics cards. It is mandatory to have both extensions together, one of them separately does not correct the problem.
      I have installed Lilu 1.4.4 and WhateverGreen 1.3.9 in the EFI/CLOVER/kexts/Other folder of the EFI partition and artifacts have disappeared. Remember that these 2 extensions are not necessary for the card to work properly, if you tolerate those very brief distortions of the screen or the noise of the fans running for a few seconds, you can live without Lilu and WhateverGreen.

      Note: authors recommend that when using Lilu and WhateverGreen with Radeon cards, NO graphic settings have to be added to Clover (Inject ATI, etc.).

      Note: these alterations, especially the brief white screen and less frequently purple lines and fan noise, are also seen in Windows and some real Macs with the same card.

      Alteration during macOS installation

      Boot from USB > Clover menu > Install macOS from Install macOS Catalina > screen works fine
      Boot from USB > Clover menu > Install macOS from MacintoshHD > black screen
      Booting from USB > Clover menu > Boot macOS from MacintoshHD > screen works fine.

      In the first and third stages, screen works fine. In the second stage the screen goes black although the installation continues. The user has nothing to do at this moment so you can leave the PC working until the Clover menu is shown again, the screen is recovered, the initial account options can be configured and you can enter into the newly installed system with correct resolution and acceleration.
      This behavior is not corrected even by placing Lilu and WhateverGreen into the USB device. At least in my case I have not found a solution for it. Yo can install macOS perfectly with that drawback of not seeing how it progresses during the second phase of the installation.

      Only 2 connectors of the 5 available work

      This card has 3 Display Port (DP) ports, 1 HDMI port and 1 DVI port. In my case, only 2 DP work, those that are further from the HDMI connector. It is enough if you use a single monitor or 2 monitors that can be connected by DP. But if you want to have 3 or more connected devices or some of them only have HDMI, it is necessary to enable the 5 connectors or at least 4 of them since the DVI is obsolete and does not allow resolutions as high as DP and HDMI.
      User foxbox has proposed a solution in a thread titled [Solved] Sapphire RX 580 Nitro + SE | black screen on HDMI and DVI. Must inject from Clover a modification to the Orinoco framebuffer (which is used in the RX 580 card) so that the 5 connectors lack a fixedly assigned address and, instead, receive it dynamically. This change is made from the KextsToPatch section of Clover. Read the post from foxbox.
      This has to be accompanied by 3 changes in the Graphics section of Clover: Orinoco in FB Name / Inject ATI / 5 in Video Ports. I have tested this solution in macOS Catalina and it effectively enables the 5 ports of the card but, since I only use 1 monitor, I have removed it and I am with Lilu and WhateverGreen.

      Bonjour,
       
      Je rencontre un souci depuis la dernière maj supplémentaire catalina 10.15.4, même chose pour la 10.15.5 aujourd'hui : après le début de l'update, lorsque le pc redémarre, je ne vois pas le volume d'installation dans les volumes de l'écran de boot clover (v5118). j'ai juste Preboot dans les volumes cachés au démarrage, et j'ai essayé de les afficher, le préboot de l'install apparait bien mais le boot n'aboutit jamais par ce biais. du coup, je suis bloqué en 10.15.4. Auriez-vous une idée du problème ?

      Perhaps it was the first NEC (Lenovo) Lavie Z HZ550 to install hackintosh. I hope more people who like Lavie Z series can experience Hackintosh at HZ550. She is really great.
       
      I found HZ550 & HZ750 on the Chinese website, which is amazing. It weighs only 790g, 13.3 inches, and the standard 2k screen, which is too attractive to me. I am a Hackintosh enthusiast. I think HZ550 or HZ750 with MacOS is the best Unfortunately, the Lavie Z series is not listed in China, only exists in the Japanese and American markets, and in the Japanese market is the NEC brand, while the American market uses the Lenovo logo.
       
      Fortunately, I got an HZ550 from Taobao. Yes, not HZ750. In comparison, HZ750 has more touch screens and 360 ° flip. These are hard to attract me. More importantly, HZ750 is about 200g heavier than HZ550 That's why I chose HZ550. Well, because he is only 2,000 RMB.
       
      The specific introduction can refer to NEC Japan official website:http://nec-lavie.jp/products/hz13b/
       
      The HZ550 hardware list I obtained:

      Advantages: small size, light weight, 2K screen, 8G memory, 512g SSD, keyboard feels good, and wireless network card can be replaced, which is unimaginable in today's thin and light books.
      Disadvantages: The sound is small, almost the same as the mosquitoes.
       
      Ok, bragging is over!
      In order to use the wireless network, I changed the wireless network card from inter 7265 to BCM94352ZAE. Some people called it DW1560. It is uncomfortable that in China, this card and his elder brother DW1830 were hyped to a high price of 480RMB. of. Fortunately, I bought it early, and this card is also very stable under win10, and there is no high delay and outage. The hard disk should be PM951 of Samsung, not PM981, which is lucky.   Before installing Hackintosh: You need to prepare a 16G U disk, SanDisk is not a rough choice for making MacOS installation disk, I used the latest MacOS Catalina 10.15.5, got config.plist from Rehabman, and put together an EFI, the latest version of clover and kext drivers. Thanks to Rehabman and the developers of the Black Apple community. I do n’t like that OC team very much.
      Make an installation disk: If you have a computer running MacOS, you can use the command line to make it, if you do n’t have a computer running MacOS, you can try VMware, I know that the insanelymac forum allows discussion, or use ether to write the image to U disk, use the EFI I provided to boot into the installation process.   BIOS setting: Press F12 at boot to enter the BIOS settings, Tab switches to "Security-Secure boot", set to "DISable", this is what we need, and switch to "Boot -Boot devices", set the U disk as the first boot item You can directly enter the clover guide interface, please follow it for google it.
      It is worth noting that the remaining space of your EFI partition needs to be greater than 200M, otherwise, the disk format will be wrong. In addition, the format partition format is APFS, do not choose to encrypt, your data is not valuable, at least you must have this awareness of Hackintosh, the file safe is also the same, do not enable, do not use to find your mac, otherwise, change the machine, OK .   Fortunately, no additional ssdt patch is required. All the patch functions are implemented through clover. The flat Apple is turned on. This is to solve the problem of the flower screen. You can find a solution yourself.
      Experience your black apple, this will bring a better experience than MacBook Pro. EFI_HZ550.zip
