|I am assuming you can't boot from CD because the BIOS option of boot from CD first is not set in your BIOS (you have not said anything about your BIOS settings).|
You can go into the BIOS and change boot priority so that your CDROM drive is before your Hard Drive in the Boot priority order.
The key to enter the BIOS varies with different Laptops.
Most normel keys for entering the BIOS are:
1. DEL Key
2. F2 Key
3. Esc (ecsape) key usually followed by F1 or F2 key
4. On newer Toshiba laptops (and I think your Laptop):-
a. Turn on computer by Holding down power button while pressing the ESC key.
The machine will beep, then display:
Check System, then press [F1] key.
b. Release ESC key
c. Press F1 key
There is more here:
Once you are into the BIOS ensure that the CD/DVD is before the Hard Disk in BOOT priority order.
If it is already then there is a problem elsewhere may be with your CD/DVD drive.
If it is not then change it so that it is.
If you are unable to make this change, then what is it that is preventing you from making this change?
☺ When everything else fails, read the instructions.
