I took the hard drive out of the computer ( used as a interface for a press ) and hooked it up as a usb drive to clone it so I would have a back up if the drive ever crashed, after cloning I took the hdd and put it back in the system and get the inaccessible boot device...after looking I think the problem is the fact that the drive letter was changed to g drive...looked at microsoft and found 1 repair but when I do the reg edit to delete the primary disk group it tells me i need to look in system and then dmio ( the repair is for windows 2000 ) and there is no dmio in windows nt work station...I really really need to get this fixed and know nothing about this operating system...any Ideas on how to fix this would be a HUGE help...thanks
