Any computer can boot from CD, you must get into BIOS[read your manual on how, I hope]. Once your there you set the boot order so that CD is on top or first instead of floppy or hard-drive. Its safe to leave it that way too, there are many freeware downloadable CDs on the net from helping you repair a system to running Linux directly from the CD drive, no-install.
If referring to the BIOS password, you will need to contact a computer shop and/or Toshiba to find out how to drain the BIOS/CMOS chip to reset it.
You need to put the proper RAM in place. Otherwise it will not be detected no matter what. It is a SODIMM, maximum 128MB.
With the recovery disks, just insert disk 1 into your drive, boot laptop to CD and your on the way to recovery.

Only way to know for sure is to download and burn a LiveCD from the Ubuntu site. Put the disc in and restart your toshiba. The live CD will boot up in ubuntu and run the OS from the CD player without changing the hard drive. That way, you will get to see how the system runs using the hardware.
The Toshiba Satellite Pro I'm using to write this answer - has a built-in DVD multi-drive (CD/DVD rewriter)
Because, you didn't choose the CD drive like a bootable, or the CD disk is not bootable.
Toshiba has USB port but no cd or DV
use to boot up the unit from the cd/dvd drive rather than the HD.
The Ultimate Boot CD website consists of a download to the Ultimate Boot CD software, a forum, and a wiki. The download's purpose and features are listed on the page.
First thing is, the CD has to be a 'Bootable CD'.Change the 'First/Primary boot device' in the bios setting to 'CD ROM'. Ususally it will be floppy disk, by default. Insert the bootable CD into the CD drive. That's it!!
