I have a Dell Inspiron 1300 that I bought used a few months ago, and after an unsuccessfull attempt to rid of the viruses and trojans, I decided to do a clean install of Windows XP or 2000. Problem is, the CD/DVD drive does not work, and I have not isolated that problem to being either the drive or the motherboard. As a workaround I bought a cheap external USB CD drive that I thought would work so I could install an OS from that. I changed the BIOS settings to have USB boot first, but the external CD drive is not recognized until Windows boots up. What can I do about this? I should also mention that when pressing the F12 post BIOS for the boot menu, I have 3 options to boot from, and neither is the USB option that I enabled in BIOS.
