Since you dont have the option to boot in dos when xp starts how would you use the format c:\ command b/c of a virus infecting my computer. The restore disc wont work b/c i upgraded my computer with new processor/motherboard, etc. I want to format the computer than use the win xp cd. I have a burnt copy of it and it says it doesnt have a lot of dlls... when its installing. gives option to retry or skip is that normal or is my disc messed up? What should i do thanks. Its the xp professional
