I've just rebuilt my Win 7 64 Bit Ultimate PC.
One thing I forgot to check beforehand was how to backup/restore my XP mode Virtual PC machine. Now I cannot find any clear answer to that question.
I've reinstalled Virtual PC and found the vmcx file. I tried to open the XP Mode file and reattach the vhd to it, but it did not work. I've got an error message that said approximately "unable to find host".
Then the vmcx file disappeared from the Virtual PC folder.
The only thing that has changed since the rebuild is the path to the HD where the vdi-files were stored.
Question: How do I get my XP mode working again?
