I've tried that with Vista DVD but can't get anywhere and as I'm only able to get to XP already tried this method (
How To Recover Vista After XP Installation | PC Tips) but with no sucess.
after the first promp i get the following message:
C: (\\?\Volume{62688536-5760-11de-9faa-806d6172696f})
Updated NTFS filesystem bootcode. The upadte may be unreliable since the volume could not be locked during the update:
Access denied
G: (\\?\Volume{62688530-5760-11de-9faa-806d6172696f})
Could not open the root directory:
Incorrect parameter
Bootcode was successfully updated on at least one volume.
