I couldn't find a problem like mine on the forum, so thought I'd post this. I have computer#1 that kept rebooting itself, so I took the drive out & put it as a secondary drive in computer#2 & works fine. But when I change the jumpers & try to make it Primary (and the only drive), it won't boot into windows. I just get the option screen & no safe modes work. The jumpers are the same as when it worded in C#1 as primary. I changed the CMOS battery & reset. Unplugged everything except drive at end of primary ribbon. Drive search all AUTO. AMD K7S5A Athlon XP 1800+ & IBM Deskstar 41.4GB 7200RPM MOD IC35L040AVVA07-0.
What am I missing?
