Hi,

I come up with an issue after I converted a Windows 7 64 bits Machine. When I try to boot the VM I got a Blue Screen 0x0000007b

To fix this up :

Boot on the Windows 7 DVD

At the Language Selection, Shift-F10 this will open a command Prompt
Run Regedit.

Load the system hive from the Virtual Machine drive:
Highlight HKEY_LOCAL_MACHINE
File > Load Hive
Choose : c:\Windows\System32\config\system
For the Name type : bugIDE

Expand HKEY_LOCAL_MACHINE/bugIDE/ControlSet1/Services/
Change the “Start” parameter value for this :

KEY = start Value
Aliide = 3
Amdide =3
Atapi = 0
Cmdide = 3
iaStorV = 3
intelide = 0
msahci = 3
pciide = 3
viaide = 3

File > Unload Hive.
Exit regedit.
Reboot the VM.

I took this procedure from several forum I try to recap, but at the end it works!
