Sorry was I bit fast there. Done a bit of reading, so I guess you just can't move a hard drive like that. ;-( well lesson learned.
Thank you very most for your answer.
Was that drive the master drive on the same IDE interface(primary/secondary)?
It was primary. Had a burner as slave.
Should I try and repair Win XP bootloader first?
Then see if SuSE have a repair option? If not then try to reinstall to get it to fix the SuSE bootloader?
Then install Grub?
Just asked about the Windows part in another forum. So it seems that the OS can't adapt to the new cpu/mobo. I dunno about this stuff.
They suggest that I run a repair and then fix the bootloader.
Should I do this and then proceed as above with SuSE?
SuSE has a rescue option but it will not accept my login and password?
