oh my bad guys it's windows 2000.
but the thing is, this computer can only be hooked up to ONE hdd at a time. the one i have on it now or the other one. when i put the 80gig in, the dell screen comes up, boots, then when for example when a OS bootscreen would pop up, it just goes black and stops
i should be able to format and install windows on the 80gig without using another hdd. this is what i'm trying to do.
