Windows 7 VM - Dreaded 7B BSOD

[BasilRathbone]

I backed my old Windows 7 system up with clonezilla and verified it was a good copy before upgrading to Windows 10. I then tried to resurrect my old Windows 7 system as a VM in VirtualBox (5.0.8-103449-Win) but always ended up with a 7B BSOD in the VM when I try booting the restored system.

I finally decided to clonezilla my Windows 10 system and restore 7 in order to follow a Microsoft's post and reset the "start" values to 0 in a couple of AHCI entries in the registry. I still have no joy after resetting my machine back to Windows 10 and restoring the "fixed" Windows 7 VM.

So I'm at a loss. Anyone have any idea what could be going on?

Stop 0x7B means it can't find the drive, probably because the controller chipset changed. IME it works better if you put the Win7 drive on an IDE controller instead of SATA.

Thanks, mpack, but I've tried *ALL* the different controller types including the three different flavors of IDE, PIIX3, PIIX4 and ICH6. Nothing seems to work.

I'm pretty sure I've determined what the problem is and I'm guessing there is no fix.

The original machine that Windows 7 came from was a HP Pavilion Media Center m7790y. The SATA mode (BIOS) has three settings: IDE, RAID and AHCI. The original host machine was set to SATA RAID ... and I don't suppose VirtualBox supports that setting.

I'd sure be interested in hearing if anyone else knows how to fix the problem. Maybe some backup alternative to clonezilla would work?

Did you try what I said?

No, moving the image with CloneZilla - or any other imager - will do nothing. That will not change the configuration of the Win7 boot manager.

Overclock.net to the rescue. I followed their instructions on changing SATA modes and have success!

All the following Keys in Windows 7 had to have their start values changed to 0 in order to switch from SATA RAID to plain 'ol SATA

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\pciide
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\msahci
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\iaStorV
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\iaStor
HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\atapi
