Hello, Currently I am trying to run Mac OSX Mavericks on a Windows 8.1 machine via Hyper-V. There are no guides online, there is no information to be found and I suspect it's due to the fact that it either doesn't work at all or it is just very hard to make OSX start up in Hyper-V.


The new Windows 8.1 hyper-v supports BIOS boot as well as UEFI boot. I thus created two virtual machines, one with BIOS and one with UEFI.




  • The BIOS version stops all DVDs and even prepared installations from a regular hard disk (I tried out MBR as well as GPT) at the prompt boot1:error or boot1:done or "bios disk read error at sector ..." I have not found any way to get past this and I tried quite a few things (DVDs like rBoot and iBoot as well as harddisk based installation media created with myHack)




  • The UEFI version simply says that it cannot find anything bootable on the drive, the exact message is: "Boot Failed. EFI SCSI Device." There are no UEFI settings or anything I can select there. This messages occurs with the DVDs and with the harddisk based installation media.




There are three things I'd like help with:




  • General ideas and tips - I know that according to all sources it can't be done, I'm just asking for a community brainstorming here. Perhaps you have an idea that I did not think about.




  • Creating a Clover installation medium on a regular harddisk. Hyper-V does not allow for adding USB devices to a VM, so instead of creating the Clover installation on a USB drive I select a regular harddisk where I put the Mavericks install files onto (with the USB installer that comes with the Install Mac OS X Mavericks.app). Clover completes without errors but it fails to create the partition 'EFI' and thus the disk is not bootable. With a USB drive Clover creates the partition just fine, sadly I cannot use USB devices in Hyper-V.




  • Are there other ways of installing OSX besides Clover, myHack and DVDs that I could try out?




Thank you! One more thing: When I say 'regular harddisk' I say this to make it easier to understand; I am actually using vhdx files that I attach in the Disk management of Windows. I prepare the vhdx file with VMware Workstation (raw disk) and then switch the file over to Hyper-V. This works fairly well, I have used it before for other operating systems. But it doesn't actually make any difference whether I use a real harddisk or a vhdx file, and thus I just used the term 'regular harddisk.'


My next steps:




  • Wait for your help and:




  • Create a Clover USB boot device and then with dd copy it over to the regular harddisk and see if it boots.
