Inaccessible Boot Device error

Post by devinr »

I've got a VHD file that I created using disk2vdh that contains an image of my old system hard drive. When I try to boot to that VHD I'm getting a 0x0000007B INACCESSIBLE BOOT DEVICE blue screen from the guest Windows OS.

Does anyone have any suggestions on where I might start in figuring out if I can fix this?

Thanks

Try IO APIC or search for the merge ide tool.

Assuming the guest is W2K or XP this thread has some good info:

Sorry..I should have been more specific.

Guest is Win7, host is Win7.

The issue is likely the same, the device driver the image booted from is not the one emulated in the virtual machine. IMHO this is very malicious of Microsoft and makes it really hard to recover from a failed motherboard.

Windows7, I think, adds the disk UUID into the mix but I'd thought that'd give a different error message, I'm not very experienced with Win7 only a light user of it on real machines and my one VM experience with it is so far positive after I stumbled on the ICH9 emulated chipset issue and switched it to PIIX3 instead.

Take a look at the thread on booting Win7 using the same disk on the real hardware and in a virtual machine, it should expose the issue. But as far as I know the only solution is to:

1) re-install as an upgrade to get the right device drivers (not easy if a lot of updates have been applied since your CDROM was made).

2) set the VM to emulate the hardware the original motherboard booted from (not usually possible as few options exist)

3) install device drivers for the emulation and hack the registry to make the system use them on boot -- you'll need to find analogous instructions for Win7 that do what the W2K/XP instructions I linked do.
