How to Boot a Toshiba From a CDby Greyson Ferguson
When using a Toshiba computer you may find the need to boot your computer from a CD. Booting your computer from a CD allows you to avoid using the installed Windows operating system. You may need to do this to correct an issue with the current operating system or to install software onto your computer. Whatever the reason, you can boot from a CD, as long as you have either a Windows startup CD or a boot disk.
Power on your Toshiba computer. Insert either the boot disk or the Windows startup disk into the CD drive.
Shut down the computer just as you normally would (click "Start" followed by "Shut Down").
Restart the computer and press "F8" over and over again. Eventually a boot screen appears on your monitor asking how you want to start up your computer.
Select the "Boot form CD" option and press enter. The computer now launches the contents of your disk. Follow the prompts of the CD to finish the boot. If you want to abort the CD boot press the "Esc" button until you return to the boot screen, then boot from the operating system.
