I purchased a used Optiplex. It of course comes with a DVD player. The machine originally was made for the Japanese market and has some Japanese OS software installed it seems. When I turn it on it shows that it is going into windows xp and then asks for where SP1 is or something like that (it is in Japanese). It shows a (dialog) box which asks where something is and has something like grouproot as the place it is looking for it. But it does not find whatever it is looking for. I have an English Windos XP disk for dell computers and I wanted to reinstall with this English Windows. I pressed F2 and assigned the boot sequence to the CD (or DVD, I forget which was written there), instead of the harddisk or the floppy drive. However it said there that the CD drive was not attached. When I try to boot up under this condition with the XP installation disk in the DVD ROM bay it says "no boot drive available". Anyone have a solution to this?
