Uh oh... I think you need to either use a Windows CD (Anyways, are you using Vista or 7?) (What edition?) (What service pack?), buy a new pair of disks (the disk 2 will not come corrupted, also disk 1 and disk 3 will not come corrupted.), or buy a new Windows Vista/7 laptop with either Windows Vista SP2 of your version, or Windows 7 SP1 or higher of your version (SP1 is based on how much security you need, SP2 has medium security and SP3 has high security. Vista list: SP1 has no updates, SP2 has low-medium security, and SP3 has high security.) XP/2000/ME/98/98SE/95/NT/3.11/3.1 are in other forums. 3.1, 3.11, NT, 95, 98, 98SE, ME, and 2000 have bad security against viruses. (3.1 and 3.11 have no viruses written for them).
