UNMOUNTABLE_BOOT_VOLUME error on migrated Win XP vdi

[jsbach1812]

I have a WinXP image that is running fine under one machine running 1.5.0 OSE. I migrated that vdi file to another machine and created a new VM under a new install of 1.5.2. I get the Windows splash screen and then the BSOD UNMOUNTABLE_BOOT_VOLUME and then it reboots and back to the splash screen and then another BSOD and reboot.

Has anyone had any experience with something like this?

Thanks

******Update*************
Permissions on the copied vdi file were set to "nobody". Once that was changed everything ran fine.

I migrated that vdi file to another machine and created a new VM under a new install of 1.5.2.

What does "migrated" mean?
Do you use VBoxManage clonevdi or just copied the vdi?
Was there a saved machine state or were there some snapshots before cloning?

I copied the vdi from one machine to another.

Better you use VBoxManage clonevdi for this.
