Laptop wont boot from cd/dvd drive, hard drive is cleasn, no viru

1. Change the BIOS boot order so the CD or DVD drive is listed first. Some computers are already configured this way but many are not.
   If the CD or DVD drive is not first in the boot order, your PC will start "normally" (i.e. boot from your hard drive) without even looking at what might be in your disc drive.
   Note: After setting your optical drive as the first boot device in BIOS , your computer will check that drive for a bootable CD or DVD each time your computer starts. Leaving your PC configured this way shouldn't cause problems unless you plan on leaving a disc in the drive all the time.
   
2. Insert your bootable CD or bootable DVD in your disc drive.
   How do you know if a CD or DVD is bootable? The easiest way to find out if a disc is bootable is to insert it in your drive and follow the remainder of these instructions. Most operating system setup CDs and DVDs are bootable, as are many advanced diagnostic tools like the ones I discussed above.
   Note: Programs downloadable from the Internet that are intended to be bootable discs are usually made available in ISO format.See How to Burn ISO file in CD for more information.
   
3. Restart your computer.
   
4. Watch for a Press any key to boot from CD or DVD... message.
   When booting to a Windows setup CD/DVD and many other bootable discs, you may be prompted with a message to press a key to boot to the disc. To boot to the CD or DVD, you'll need to press any key on your keyboard (like the space bar) within the few seconds that the message is on the screen.
   If you do nothing, your computer will check for boot information on the next boot device in the list in BIOS (see Step 1) which will probably be your hard drive.
   Some bootable CDs and DVDs do not prompt for a key press and will start immediately.
   
5. Your computer should now boot from the CD or DVD disc.
   Note: What happens now depends on what the bootable disc was for. If you're booting to a Windows 7 DVD, the Windows 7 setup program will begin. If you're booting to a Slackware Live CD, the version of the Slackware Linux operating system you've included on the CD will run. You get the idea.
   If you tried the above steps but your computer did not boot from the CD or DVD properly, check out some of the tips below.
   

1. Recheck the boot order in BIOS (Step 1). I've found that the number one reason a bootable disc won't boot is because BIOS is not configured to check the CD/DVD drive first.
2. Do you have more than one CD or DVD drive? Your computer probably only allows for one of your disc drives to be booted from. Insert the bootable CD or DVD in the other drive and restart your computer.
3. Clean the CD or DVD. If the disc is old, as are many Windows Setup CDs and DVDs by the time they're needed, clean it. A clean disc could make all the difference.
4. Burn a new CD/DVD. If the DVD or CD is one you created yourself, like from an ISO file, then burn it again. The disc may have errors on it that reburning could correct. I've had this happen to me more than once.
   

Hi usavahe.
Booting from CD should be possible.
1) When the laptop first starts to power up, repeatedly press the F12 key. This should bring you to a screen that lets you select the boot device.
2) For the Satellite, it may show icons across the bottom of the screen. You want the one that looks like a CD.
3) It should the start to boot from the Windows CD (if it is indeed a bootable disc) and you will see the message "press any key to boot from cd".
4) Press any key you want on the keyboard and the Windows CD installation process should begin

Hope that helps
