I pre installed win 2000 on a hard drive for a friend (works fine in my
system). When I put it in his machine it gets past the dell boot screen and
on to the "starting windows 2000" screen. When the progress bar is full it
jumps back to the boot screen and goes through the same process untill I
switch it off. Please help.
