Vista is too big for a CD; all disks are DVD-ROMs. The full versions are
bootable. I'm almost sure that the upgrade DVD is bootable, too, but I've
never had one so I can't be sure.
Booting from CD/DVD can be tricky in some computers. On many, a message
appears on the second boot-up screen that says to "press any key to boot
from CD", or similar language. If no key is pressed, the computer proceeds
to boot from the hard drive.
If you tell us which computer make and model you have, or which mobo/BIOS if
you built it yourself, someone here will probably recognize it and know the
proper steps to boot that machine from CD/DVD. If you don't, we'll have to
guess, like I just did, and we'll likely guess wrong.
