I will try to make this short. I was running a Win2K system that stays on most of the time. I shut down just to “refresh” the system and it would not re-boot. Got stop error, blue scren, inaccessible boot device. Never recovered. Put in another HD with win2k and booted fine, but didn’t have the PW to completely get in the system. Took a fresh HD and re-installed WIN2k and system booted fine. Got the old HD back from data recovery and decided to install a new motherboard and processor to upgrade before putting all the data back. Took the new HD I had just installed Win2k on and tried to put in the “new system” after installing the motherboard and processor and got a stop error, blue screen, inacessible boot device. I was told that the reason was you cannot “swap” HD’s like that. The new system boots with a WIN98 drive, but not with Win2k now. Is this correct and will re-installing the o/s again get the drive working?
