Re: A computer question to those who know...
I just cleaned the drive on a laptop, so it's kind of fresh in my mind. There is really no better way to install a new system for minimum bugs.
Any operating system package (Windows in particular) should come complete with a startup floppy with all the necessary drivers automatically built in to allow your computer to read the CD-ROM. Don't start until you have it in hand.
A newer Mac can boot from a CD. I've never managed it with a PC, although maybe some have a bios that allows it.
