In Topic: [Guide] Mavericks 10.10.X - Dell Optiplex 780 (760)

30 April 2015 - 03:05 PM

(I have the Optiplex 760 SFF)


Okay I managed to destroy the installation of both haha. I could make Windows 8 (or server 2012 R2 in my case, but it is essentially the same) boot while Yosemite installed. Then it boots from the partition where Windows is installed to (and not the EFI partition) But of course Yosemite will only boot when I use an USB-drive.

I can make Yosemite boot with clover, then it boots boots with clover from the EFI partition. Yosemite works fine then but Windows won't boot. I can get the Windows partition in the clover list (when I put scan with Clover Configurator to legacy) but it won't boot Windows cause it will say the MBR is broken or faulty or something like that. I have tried hours to make it both bootable.


But now I did something and I can't get Windows to boot again haha.. And I've put so much effort in it to make Server 2012 R2 usable for desktop use, lol. Tried all the fixboot/fixmbr/scanos/rebuildbcd and even the bootsect.exe /NT60 stuff but nothing. Linux boot repair also didn't fix the problem.


So my question is, is here anyone who got this Optiplex 760 working with dual boot? I only have place for one harddisk (SFF). I also don't have the \EFI\Microsoft\Boot\bootmgfw.efi, I guess this is because of the lack of UEFI support? What happens if I manually add this file?

I used GUID like mentioned in the guide, why do we need to use this and not MBR?

Would chameleon or something make it possible to use dualboot?

Try "Install boot0ss in MBR" instead of "Install boot0af in MBR". This is the specific boot file when you have both OS X & Windows on the same drive.

thanks, this worked to boot osx without the usb-drive. But now clover won't show the option to boot Windows haha. How can I add the Windows to clover?

I now have some time to try things out. I have an Optiplex 760 running Yosemite 10.10.3 so I can make a bootable stick. I have a few questions:

1. Can I just use the same method as I used with my Optiplex 760?http://www.insanelym...tiplex-780-760/
But instead of his Clover files, I'll use your Clover files from your guide. That way I don't need to have two USB-drives
2. What custom clover options should I use for the L502x to install to the USB-installer?

And a third question what's more a general question. I first made an USB-disk with a Mac Mini following the Optiplex guide. Partitioning the USB-disk with GUID and one partition and in the end install Clover to the disk. When I did there was a EFI partition in the end to copy the Clover files to. I tried to repeat these steps on my Optiplex running Yosemite 10.10.3 and an other USB-disk, but every time I tried this, no EFI partition was made. Is this the fault of my hackintosh? My usb-drive? Or something else?
edit: Okay the EFI partition is made, but Yosemite won't show it. I can see the EFI partition when I plug it into a Windows computer. How can I make this EFI partition visable in OS X?

I found how I can mount the EFI partition. I made a stick to try it out but have the lack of time to test it now. I'll report back later when I have tried it.

How can you make a dual boot? I followed the guide here but except of 1 partition, I made 2. And I installed OS X to the first one. After that I followed all the steps and all worked fine and Yosemite booted as I wanted it to boot after the post install clover installation (8. Installing Clover on you Hackintosh)

6. Install OS X Yosemite.
This part is the most time consuming. Using a USB 4G flash drive will help things out quite a bit.
  • Shut Down.
  • Enter Bios via tapping F2 during boot.
  • Change SATA Operation to AHCI (Leave the Booting mode on Legacy! UEFI is not support/does not work.)
  • Click Save and reboot
  • Press the F12 key to choose boot device, select USB Drive
  • When Clover boot screen is visible, choose Boot "Mac OS X from Yosemite".
  • The system will then boot into OS X Installer.
  • For a new installation of OS X, you MUST erase and format the destination drive according to the following steps before continuing. If you are upgrading from Lion, Mountain Lion or Mavericks and you want to keep your files and apps, skip steps a-j.
    a. Choose Disk Utility.
    b. Highlight your target hard drive for the Yosemite installation in left column.
    c. Click Partition tab.

    d. Click Current and choose 1 Partition.
    e. Click Options...
    f. Choose GUID Partition Table.
    g. Under Name: type YosemiteHD (You can rename it later).
    h. Under Format: choose Mac OS Extended (Journaled).
    i. Click Apply then Partition.
    j. Close Disk Utility.


But now I've installed Windows Server 2012 R2 to the second partition and of course it will only boot Windows at first. I can still boot Yosemite with an usb-drive. But After fully installing Windows I wanted to install clover again and I followed these steps again:


8. Installing Clover on you Hackintosh
These settings will install the bootloader to the system drive's EFI partition automatically as part of the scripting. After completion, the system drive's EFI partition will automatically mount.
A few more changes need to be made to the default Clover installation:
  • Run the Clover installer once again, select the following things show in the image below.
  • Open Clover package installer.
  • Hit Continue, Continue, Change Install Location....
  • Choose the USB, now called YosemiteHD.
  • Hit Customize and install Clover with the following Custom Install settings: ( see image)


But it is still booting Windows Server 2012 R2, I don't get a clover bootscreen. How can I install this clover dual boot again?

Cool, then I won't rush with the script revision. 

You can set it to Legacy only and install Windows, then switch it back to UEFI and it would still boot in Legacy.

Okay nice, I thought Windows would be unbootable when you switch from bios type.

But you have this written in your guide:


Also I should mention that booting Legacy Windows from UEFI Clover is a big no go with Tiano firmware, so don't expect that. The only way to access Legacy Windows is to either use F12 and choosing Hard Disk or exiting Clover.


How would it look like when I install Windows in legacy on my main SSD and EFI OSX on my caddy HDD? (bios switched back to UEFI mode)

Then I won't get a menu where I can choose between Windows and OSX? But instead I need to close the Clover bootloader in order to start Windows?




Well, Mark, I don't really have enough time to explain detailedly but I do have OS X and Windows working toghether without UEFI (legacy mode) on my XPS 15.

As long as the bootloader sits on the internal drive, it will be able to boot the system installed on the caddy just fine.


On my particular setup I do have OS X Yosemite installed on the SSD placed inside the caddy (couldn't bring myself to open the whole thing yet - I quite hate dealing with hardware) and Windows 8.1 installed on the HDD placed inside the laptop. My bootloader (Chameleon, btw) loads from the HDD and then points either to OS X on the SSD or to Windows within the HDD itself.


The system is running just fine and the only thing that broke compared to Mavericks are the brightness keys (you can still use a small C program called screenbrightness - Google it - or OS X's ordinary control panel to control it, though).


The necessary kexts and other files used to disable nVidia's GPU and get other parts of the system working can be found whithin this topic. The only kext that I needed to modify in order to get it working was the one responsible for the ALC665 audio controller (you can find how to do it here, on Insanely Mac. There's a topic somewhere).

Oke good to hear. Do you have the modded bios and UEFI enable? (So installed Windows with UEFI disabled and after installation enabled UEFI again) Or does Chameleon not require UEFI?



Sorry for all the questions, I really appreciate your help
