Cannot boot Windows CD-ROM - Therefore Cannot Fix Windows

Question

When I switch on my laptop I'm instantly presented with the screen asking me to select Start Windows Normally, Safe Mode and Last Know Good Configuration. Whichever option I select, it then says "The file Windows\System\Config32\System is either corrupted or missing. Insert the Windows CD-ROM to attempt to repair this file."
OK, so I insert my Windows XP Pro CD-ROM and my laptop simply doesn't load it. I decide to go into BIOS settings (by pressing 'Esc' when the "Toshiba" screen displays) and change boot priority to CD-ROM > HDD > FDD > Lan. This also did not work. How am I supposed to fix my XP installation if I can't even boot the CD-ROM?
Please help! Thanks

Thanks for your reply but your solutions, sadly, did not work for me. I have a Tecra 9100.
Press and keep down C button after switching notebook ON (Made constant beeping sound - Did not work)
Choosing boot device after pressing F12 button (I tried every option - Did not work)
Changing booting order in BIOS (I put CD-ROM first - Did not work)
Hmm... Maybe I should have mentioned that it says "Media test failure, check cable" when I select CD-ROM first. Does this mean my CD-ROM drive is broken? I hope not. This laptop is second hand with no warranty. But it shouldn't be broken, it worked perfectly fine before the problem. It played CD's and DVD's just fine before. Besides when I insert the Windows XP CD-ROM, the disk tray lights up as usual and I can hear the disk spinning smoothly as usual, that is though for a few seconds in this case.
As for the 'different bootable medias' I only have Windows XP. I'm afraid I don't have Linux. I do however have a floppy drive. Does this mean I can use a floppy disk as a bootable media? And if it helps, the laptop I'm using to write this has a CD burner (maybe I could burn Linux on a CD?).
