Lots of difficulty getting a VM built in VirtualBox. The process that's got us some of the way there has been:

• Move the GHO files to a shared folder (shared in VirtualBox)
• Boot to a BartPE disk with Ghost
• Map the shared folder to a drive
• Restore from that shared folder to the drive in Ghost

However, although the drive seems to have been created correctly, the results are not bootable. I can log on to the Windows install on the drive (and I now have two other ones, due to trying to recover the original using an XP disk), but I still can't seem to boot it. I'm going to keep hacking at this, but we may have to go through the whole process again, with more thought going into it. It's possible I should have restored to a disk rather than a partition. I'll try that tomorrow.
