|One item to consider too...|
If your b/f has files on the drive he would like save... then do NOT run any routines that in effect wipe the drive as is. That includes any programme/routines that restore to factory gate settings (restoring to how it was when new).
There are simple ways to allow you access the entire drive and save files etc. - even though cannot boot into it properly at present.
Need more info on this - post back...
