I am trying to clean up a friends PC that was full of spyware and some viruses. The PC is a Dell dimension 2400 w/XP home. I am trying to reinstall xp home from scratch to begin new but I cannot get the pc to boot from CDROM or from floppy after making the appropriate changes in the BIOS. suspecting something might be wrong with the BIOS i have even pulled the battery out to reset back to factory defaults. that did not work. I even tried booting from USB but that won't work either. I can't update the BIOS because you need to boot from floppy to do that. I'm stuck. please help!!!
