Install on to RAID MBR partition

5 posts in this topic

Recommended Posts

Hello,

First off, I have been around the hackintosh scene casually for a while so I'm not completely new.

 

I own an MSI GT683r-242us, which has an intel i7 2630qm processor and two 500gb hdd. Now, currently my two hard drives are striped in RAID 0 configuration with two partitions, one containing my Windows 7 install, and the other is blank storage. This stripe is set up as an MBR partition table. For me, I am forced to run mac on an external hard drive.

 

Here is what i'd like to know:

 

Is it possible for me to access the storage partition of this set up so I can install OSX natively onto my internal hard drives? Is there a way to get disc utility to see the two partitions the my windows machine sees, instead of 3 different drives that are of inconsistent size when compared to the real partitions.

 

Furthermore, if anyone knows a way to backup my windows OS by mirror imagining it so i can disable RAID and use the two hdds independently, (basically, i dont want to have to reinstall everything[possibly norton ghost? i dont know how it works tho]))

 

 

Thanks a bundle in advance.

Short answer is no, you can run OSX from a software raid as seen here, which works quite well but would not be recognized by Windows. Hardware RAID would require a card that works native in OSX and Windows which aren't cheap. You might be able to split each drive into 2 partitions and make software raid using one partition from each drive, leaving the other 2 for windows OS and data, giving you 2 250gb partitions and one 500gb OSX only software RAID. Not sure off hand if this will work with MBR vs GUID partition scheme or as a hybrid and care would need to be taken that Windows does not rewrite the bootloader

I did some raid testing last year with a old AsRock Motherboard and I was able to boot into a raided HDD setup but only with a third HDD or USB drive that had just the boot loader installed on it. What I did was the following:

 

1. Created the Raided HDD in the Raid BIOS

 

2. Booted into the Mac OS X install and went to Disk utilities

 

3. Mac OS X saw my drives as two different drives so I reformatted and created a software raid between the two drives.

 

Note you will lose all data present on these HDD when doing this step

 

4. Then I installed Mac OS X to the drives

 

5. Booted off of a USB drive that I mounted internal in the case

 

6. The boot loader see the two HDD as separate so I selected the one and the Boot failed and then selected the other and it booted in

 

7. I was getting the same raid performance as I saw under Windows

 

I ran this setup for about a week and then tore down the setup and I have not tried this again yet but perhaps I can in the future...

Well, yes it's possible but with some caveats as mentioned. No you wouldn't have to kill Windows if you have NTFS cloning software, CopyCatX is only OSX app I know off hand that will clone NTFS volumes. No 3rd boot drive needed unless preferred as Apple software RAID creates a un-raided helper partition on each drive that can be read by bios and Chameleon can be installed there, it is where kernel cache loads from until the RAID drivers are loaded and OSX can then finish booting off the array. My boot times after Chameleon starts are literally a few seconds. I've been doing it this way for a couple years now with no problems. I linked a How-To in my first post if you ever wanted to know more than you probably really want to :)

      - NVIDIA GeForce GTX 950M: Optimus not supported.
      - Card Reader: Unsupported -> Can't really fix because I don't have any SD Card at the moment, maybe can be fixed by adding Prod & Ven IDs to AppleStorageDevices.kext, I never used it anyway. name: "USB2.0-CRW" Prod ID: "0x0129" Ven ID: "0x0bda  (Realtek Semiconductor Corp.)"
      For Wi-Fi:
      - 1st method: You can choose an external USB wifi dongle (I used TP-Link Archer T1U (5GHz support), TP-Link has official macOS drivers, you just need to install it
      - 2nd and I think the best method: Replace your M.2 Qualcomm Card with a compatible BCM94352Z card (you will have hand-off Bluetooth too), just install the kexts (enabled with BrcmFirmwareRepo.kext, BrcmPatchRAM2.kext, FakePCIID.kext, FakePCIID_Broadcom_WiFi.kext, they're all in my attached zip). You could buy this card from ebay, aliexpress, or amazon
       
      Issues:
      - None
      BIOS Settings:
      - BIOS version 1.15 (irrelevant)
      - Secure Boot: Disabled
      - Touchpad: Advanced
      - Boot mode: UEFI
      Getting ready for Installation:
      - Download the Catalina install zip (bootpack & postinstall): acer_aspire_V591G-55TU_cata.zip
      Installation:
      - Create an installer with any method you know (- Mac: createinstallmedia - Windows: Transmac, Vmware, Win32diskimager)
      - Copy my Clover folder to the USB's EFI folder
      - Boot with the Installer USB
      - If you stuck in boot, reboot and in the Clover bootloader select "config_debug.cfg" -> you'll have more informations about the freeze
       
      Please open the README.rtf in my install zip for more informations about the USB Installer & Post installation!
      On Catalina the System folder is read-only, so you need to remount in rw to modify System/Library. 
      If you have a single RAM and getting panic at boot, then you need to edit the "config.plist" with these (SMBIOS->after "Version 1.0"):
      ->Edit "Frequency" and "Size" to match your RAM values
      <key>Version</key> <string>1.0</string> <key>Memory</key> <dict> <key>Channels</key> <integer>1</integer> <key>SlotCount</key> <integer>1</integer> <key>Modules</key> <array> <dict> <key>Slot</key> <integer>0</integer> <key>Size</key> <integer>8192</integer> <key>Frequency</key> <integer>2133</integer> <key>Type</key> <string>DDR4</string> </dict> </array> </dict> </dict>  
      PowerManagement  fix:
      Set HWPEnable=YES in Clover (already set), CPUFloor to "700", Frequency to "2300" and "3200"(Normal and Turbo, if you have i7-6700HQ version then it should be "2600", "3500") and "FrequencyVectors" from "0x0d000000" to "0x07000000" in "S/L/E/IOPlatformPluginFamily.kext/Contents/PlugIns/X86PlatformPlugin.kext/Contents/Resources/Mac-A5C67F76ED83108C.plist", MSR _xcpm_idle Patch to KernelToPatch in Clover (If you have High Sierra, change "MatchOS" to 10.13):

      <key>KernelToPatch</key> <array> <dict> <key>Comment</key> <string>MSR 0xE2 _xcpm_idle instant reboot(c) Pike R. Alpha</string> <key>Disabled</key> <false/> <key>Find</key> <data> ILniAAAADzA= </data> <key>MatchOS</key> <string>10.14</string> <key>Replace</key> <data> ILniAAAAkJA= </data> </dict> </array> Reboot, and it's 800MHz in idle state, same on Windows.
       

      Elan SmartTouchpad
      I only use scrolling, one-, double- & tripletap
      If you want to try other gestures go to this link for more informations, options (v4.6.5) ->  DETAILS ABOUT THE SMART TOUCHPAD DRIVER FEATURES
      Fn Brightness keys not working with this, tried several things without success. With VoodoPS2Controller it's working, but you'll have no gestures (neither scrolling).
       
       
      Before updating to a new version of Catalina please update kexts (and clover if necessary) to newer versions to avoid kernel panics.
      Generate a serial number with Clover Configurator.app (open up your config.plist with CC then -> SMBIOS -> Serial Number -> Generate New)
       
      Catalina & Windows 10 Dual-Boot:
      Dual-boot clean install (on one drive), UEFI Only:
       
       Boot into your Mac installer, Create 2 partitions in GUID table (1 for Win (I used FAT32 but I think it doesn't matter what you choose), 1 for Mac),   Install Mac, boot with your USB, mount your EFI partition (use terminal or an EFI mounter app), create an EFI folder (if there is no folder), copy the CLOVER folder I attached to the EFI folder, restart,  Boot into your Win installer, Format the partition you created for Win, install.   Now, it's automatically booting into Windows. To use Clover open cmd in administrator, type:  bcdedit /set {bootmgr} path \EFI\CLOVER\CLOVERX64.efi       5.  You're done! It will booting into Clover when you start the system, and you can select Win or Mac (or another OS if installed on a 3rd partition).
       
      Dual-boot with Windows installed first (on one drive), UEFI Only:
      If you already have Windows and you don't want to lose all your data there is a hope:
      I created a video from this restore method: [Hackintosh] Dual-Boot High Sierra & Windows - when Windows already installed - no data waste - UEFI
      You need bootable Mac Installer and a full system restore image (link is in my video's description).
      (You may see errors if your EFI partition is not 200 MB)
       Boot into your Windows, resize your partition or create one for Mac.  Boot into your Mac installer and in Disk Utility format the partition you created.  Restore from image: select your full system restore image.  When it's finished restoring you just need to restart, then boot to the system with your usb.  When you successfully booted to Mac desktop, mount your EFI partition (use terminal or an EFI mounter app), open EFI, you will see there is a Microsoft folder already (don't touch that!). Copy my CLOVER folder to the EFI folder then Restart.  Now, it's automatically booting into Windows. To use Clover open cmd in administrator, type:  bcdedit /set {bootmgr} path \EFI\CLOVER\CLOVERX64.efi       7.  You're done! You can select your old Windows and your new macOS!
      (Only tried with Windows 8/8.1/10. I don't know Windows 7,etc.)
       
      IF YOU GETTING ERRORS DURING MAC RESTORE:
      - Make sure you have partitions in GPT
      - Windows using 100 MB EFI and will annoy the Mac restore. Don't worry, just ignore the errors.
       
      IF YOU GETTING ERRORS DURING WINDOWS INSTALLATION (could not be formatted, etc):
      - Make sure you have GPT partitions, and GPT (UEFI) installer, also disconnect all external storage drives (except the installer USB)
       
      IF YOU USED RESTORE METHOD THEN CAN'T MOUNT YOUR EFI PARTITION (No EFI partition found):
      - It's because your EFI is not 200 MB or not an "Apple" original EFI,  but do not worry, try another EFI mounter, or mount from terminal (I used EFI mounter v3: Getting errors, but you can mount and use without problem)
      - You also could "mount" the EFI from Windows:
      1st method: open cmd in administrator mode and type:
      diskpart list vol (Now select the "System" volume,(FAT 32) For example I select 4) sel vol 4 list part (Select System type partition, for example 2) sel part 2 assign letter=b (This will "mount" your EFI partition) Open Explorer++ or TotalCommander in administrator mode to manage EFI remove letter=b (This will "unmount" your EFI) 2nd method: open cmd in administrator mode and type:
      mountvol b: /s (This will mount your EFI) Open Explorer++ or TotalCommander in administrator mode to manage EFI mountvol b: /d (This will unmount your EFI) Thanks to all OSXLatitude members for helping me out! (Jake Lo, Hervé, Bronxteck, black.dragon74)!

      So I've searched all the internet but haven't found a reliable answer: I have 
      1) My SSD with Windows from which I'm now writing this post
      2) My EFI SSD where: a)EFI partition b)APFS container (partition with apple volumes inside such as preboot,recovery,system) c) NTFS volume
      (b) is physically 150GB but only 110GB is occupied inside APFS 
      3) MY GPT HDD where I have d) primary NTFS partition 150 GB free space
      I want:
      1) backup (b) to (d) as file.backup
      2) remove (b) from (2) / extend NTFS partition etc use SSD for windows only
      3)some time later be able to create "150GB" (or better 120GB) "unallocated space" on  (2) alongside EFI and NTFS partitions and recover my APFS partition from file.backup to "unallocated space" so that I could normally (as I do now) boot EFI->CLOVER->THAT_APFS_MACOS
      How do I do that under windows os (or at least other OSes) ?

      Patched OSInstaller.framework to allow macOS 10.15 installation on MBR HFS+ partition.
       
      Please read Readme-10.15.pdf first.
       
      How to finish the Catalina installation.
      1. Use EasyMBR-Installer1015 to make USB Catalina Installer.
      2. Boot to USB Catalina Installer, open Utilities -> Disk Utility, format as MBR HFS+. 
          Install Catalina to blank MBR HFS+ "Target" partition.
      3. Boot to USB Catalina Installer, open Utilities -> Terminal, run the script command:
          copytempdata
      4. Boot to "Target" MBR HFS+ partition on single user mode (-s), run the script command:
          hfsupdatecache
      5. Reboot to "Target" MBR HFS+ partition, setup user name and login, finish the installation.
       
      Also, you need to setup Clover as BooterConfig=0x28, CsrActiveConfig=0x67
       
      ----------------------------------------------------------------------------------------------
      List of known issues:
      1. Some app-pkg-installers can't install to HFS+, but install to APFS fine.
      ----------------------------------------------------------------------------------------------
       
      What is this patched OSInstaller doing?
      1. Pass the MBR check, allow macOS 10.15 installation on MBR partition.
      2. Pass the Firmware check, bypass the error of "An error occurred while verifying firmware".
      3. Pass auto-convert to APFS , "ConvertToAPFS=false" is no longer worked with 10.15.
      4. This MBR-Manual-Method will never convert to APFS, and will always install as HFS+ partition.
      5. This MBR-Manual-Method works with both MBR HFS+ and GPT HFS+ partition (GPT+recovery).
      No longer need to set new SMbiosversion, FirmwareFeatures, and FirmwareFeaturesMask with this MBR-patch.
       
      What's the difference between createinstallmedia method, MBR-Manual-Method, and MBR-Automatic-Method?
      As the following....
      1. createinstallmedia method,
          needs stage 1, stage 2 installation process, which is worked with GUID partition only, always convert to APFS format.
      2. MBR-Manual-Method (same as 10.12),
          install via stage 2 manually, which is worked with both MBR HFS+ and GUID HFS+, will never convert the partition format.
          We can manually format as MBR HFS+ or GPT HFS+ on installation screen like as 10.12.
          We can manually select MBR HFS+ partition to install 10.13, 10.14, 10.15 on installation screen now.
          Needn't to update the MBR-Manual-Method files, it will still work on 10.13, 10.14, 10.15 future versions, I think so.
          It can be installed as Fresh installation on formated blank partition only, but can't be installed as update from previous version.
      3. MBR-Automatic-Method (new for 10.13+),
          End of MBR and HFS+, there is no more MBR HFS+ patch available for 10.15 native OSInstaller.

      How to make 10.15 installer for MBR (MBR-Manual-Method)?
      Just use EasyMBR-Installer1015 to make installer, it works with both MBR and GPT.
      Read HowTo inside the dmg first, same as 10.12.
      Read HowTo Q/A Q4. How to patch to work with CPU SSE4.1 only for Mojave, Catalina?
      Read HowTo Q/A Q6. How to download the full installer app via swscan.apple.com, instead of App Store?
      Read HowTo Q/A Q7. How to update 10.15.x combo-update to MBR and GPT with installScript directly?
       
      And, need a SMBIOS supported with /System/Library/CoreServices/PlatformSupport.plist.
       

       
      Q6. How to download the full installer app via swscan.apple.com, instead of App Store?
      A6. Some people download installer app from App Store, and get only 18 MB size, not the complete installer app (5.68 GB). You should boot to 10.12, or 10.13 to download it again from App Store, or use script Q6-DownloadFullApp/installScript_fullapp to download the full installer app via swscan.apple.com.
