i was wondering if there a way to force it to boot the cd without the cd being bootable.
I suggest getting a diagnostic disk for the harddrive and low level formating it, cause it sounds like you have a virus on the HDD anyway!
If you have a virus and its gotten in your boot record a WinXP format won't remove that, a low level format, or disk wipe, or zero fill, wipes the entire HDD including any old boot record.
Then clear and reset the CMOS and try to reinstall from that point.
If all that fails and you have a floppy drive, you can download a set of WinXP floppy bootdisks from
www.bootdisk.com thats slow but pretty much bullet proof, unless you're experiencing optical drive hardware failure and when the time comes for the boot process to switch to the optical drive it won't.
When you say CDROM drive I hope you're refering to either a DVDROM, CDRW, DVDRW, and not an actual CDROM drive, cause WinXP doesn't like old CDROM drives, the first error it receives it defaults to PIO transfer mode!
So if you are still using a CDROM drive Lose it, I haven't used an actual CDROM drive in 2 1/2 years!
