Hi, thanks everybody if you respond; it will be a big help. My Toshiba M100 Satellite laptop has massive amounts of very evil viruses that the people at the computer store did not manage to fix, so I am just going to totally reinstall Windows. However, one symptom of the viruses seems to be that my CD/DVD player no longer works (or it may simply be broken, hard to say). Therefore, I need a way to reinstall XP without the use of a CD drive. I already checked and found that Toshiba does not include a recovery file on the hard disc. I do have my CD and a valid registration key. I am open to any solution, including those involving pirating a copy of XP since I have a license for it anyway. Thank you so much.
