Help Win7 host WinVista guest

[sacchetta]

I have a HD image of WinVista Home that a made using the disk2vhd utility.
I installed Virtualbox 3.2.10 on my desktop with Win7.
I try to start the Vista image and it runs properly but it stops accidentally with a blue screen (to fast to read) and the virtual system just restart.
This happens every time I try to start it.
I have a log.
Can someone help me pls?
Sorry for my English I'm not a native English.

Will the virtual machine start in safe mode?
Was it 32 or 64 bit?

Thank you for your attention.
What does mean "in safe mode"?
Windows Vista was 32-bit.
Windows Seven is 64-bit and Virtualbox is installed on it.

Turn off IO APIC in the guest settings.
to start Windows in safe mode you press F8 at boot time then select safe mode.

Ok I did it.
The loading process stops on the file crcdisk.sys

Sounds like you have a corrupt vhd. If you still have the disk from the Vista install I would run disk2vhd again.

I have converted a Vista installation to vhd using disk2vhd a couple of times and it worked with no problems.

I have the following problem:
when I run Disk2vhd it looks fine until the last phase but it will not present the close-button. It stops with full-progress-bar (means it should have done the system disk convertion) and the cancel-button is still active.
When I press the cancel-button (after waiting a long, long time), it takes no notice about that. So I have to press the (x) to end it.............
Any suggestions to make a good .vhd image on Vista?
(maybe disabling the antivirus?)
