Hello, I have a physical disk with a Windows 10 installed, which I'm trying to convert to a virtual disk and boot it in a VM in Unraid.

I do have access to it, it's mounted on the same machine as Unraid, and I could even boot to it if necessary.

 

First I tried using VHD2Disk to obtain a .VHD file which I converted to a .img file using qemu, and I called it "RICARD-PC.img". My first attempt was with this config:

 

 

When I tried to boot it, I got this error page (in Spanish, sorry):

 

 

 

I then tried to follow this guide 

 

And also this other (oficial?) guide

https://docs.unraid.net/unraid-os/guides/convert-windows-to-vm/

 

I tried the "qemu-img convert" command to generate a new .img directly in unraid, from the not-booted/mounted original drive, which I called "RICARD-PC_qemu.img".

 

I tried with some options from those guides: setting the Primary vDisk Bus to SATA, change the BIOS to OVMF (since otherwise it was stuck at "Booting from Hard Disk") etc, but I can't get anything to work. Here's an example of a config I tried:

 

 

But no matter what, I always get this page:

 

I read about writing "exit" and then "continue", I even tried looking at the Boot manager of the BIOS:

 

But after "continue", I get back to the black "UEFI" screen, and the loop starts again...

 

I read several guides/tutorials, and tested some changes but I don't know what else to do.

 

I'll appreciate some help, thank you.

One thing to note that I remembered, is that that Windows was installed using Legacy BIOS (MBR)

I've had better luck doing a disk image backup from the running bare metal machine, then doing a restore to the VM. Acronis has some advanced migration options that help with moving a windows install to what is basically new hardware.

I ended up booting the windows, and using mbr2gpt.exe to convert the disk to MBR, and THEN use qemu to create a .img, and using OVMF BIOS and SATA for the disk.

I saw no (at least obvious) way to make it work with it being MBR.
