But a system restore isn't the same as a reinstall which would be done with recovery disks or from a recovery partition on your original hard drive. If that's what you want to do and have the recovery disks then set the cdrom as the first boot device in cmos/bios setup and boot from the cd. If you don't have the disks then hopefully you'll have a recovery partition. Check your manual to find out how to boot from it.
