I bought a new hard drive for my old pc, it was a 120 gig western digital, i used to use windows 98 on it, because it didnt need windows xp, so my dad wanted to mess around while i was gone and try to put a bootleg copy of win xp on it, now whenever i try to start up my pc i get an error, when i try to reformat using windows 98 it doesn't recognize that there is a c:, it says that there isnt one "invalid drive" or somthing. Is there any way to clear the hard drive so that I can retry to install win 98 or what should i do? please help!!!
