Hi Guys, Here's one thats making me scratch my head a bit. I have a 200gig SATA drive split into 3 partitions, 2 with O/S's on (both XP pro sp2) and the remainder is left for general storage. One of the partitions I use only for games, however, I am trying to install Doom 3 and it refuses to, heres what happens. I boot into the Games Partition (my H: Drive) I put the CD in and when it asks if I want to install into the default dir C:\ program files\bla\bla, I change the root drive letter to H:\ The Install kicks in but then the progess bar comes on and just sits there. Eventually it times out (sorry, I cant remember the exact error message) This happens with a few games. UT2004 goes on OK but I know that it doesnt install any system files (is that the problem here?) The Partition is a Primary one and not just a logical drive. Any Ideas?
