Hi,
Not sure why the formatting in your first post was showing the codes ??
Do you have the original XP installation CD - not recovery disks ?
============
You could try putting the HDD back in the XP machine and do the following:
Switch on ..........tap F8 and get to the Advanced Startup Options.
Select Safe Mode - Command Prompt.
At the prompt type .......%systemroot%\system32\restore\rstrui.exe ............ENTER
This should start System Restore.
Select a date prior to the start of the problem.
Files / data will be OK
