Hello all,

I installed Windows XP SP2 on my VirtualBox and everything worked great. I installed everything I needed. Suddenly one day it wouldn't boot into Windows and gave me a BSOD.

Took me a while to screenshot the blue screen:

Unmountable Boot Volume
Stop 0x000000ED

Mac OSX VirtualBox - updated.

This topic was the closest I could find but I tried the suggested ideas and they didn't work:

Any ideas what is going on?
Thanks!

Did you update VB after you created the VM a few times? If so, check if the settings are still the same, especially the PIIX setting. You might want to try to change that setting and see how that goes.

Yep I tried that. Adjusted every setting I could. No I hadn't updated prior to the crash..I tried the update after but it didn't change anything.

Not sure if this will help you, but I had a similar problem: I made a backup copy of my XP drive image to a DVD drive, and copied the file back to my computer to test it (to make sure the copy on the DVD was OK). When I tried to run the copy, I would get a BSOD with a similar message.

The problem is that both the file I wrote to the DVD (which was still on my HD), and the one I copied from the DVD were identical according to "diff". After poking around for a little while, I noticed that the permission for the file I copied from the DVD was different than the original file: The copied file had a read-only permission for me (the owner), while the original one had read-write. Once I changed the permission to read-write, the disk image worked fine...

I moved my portable harddrive from XP to a Vista machine and had to give full privledges to myself and the "CREATOR OWNER" Account!

I got the same error message after trying to recover a VM from my backup.
After setting write permissions to the correct user everything work fine.

First of all I tried a "chmod 777 image.xvi" and after that I changed the permissions exclusively to the right user.

Hope it helps.

Regards,
