Good reply! Now we are gettings somewhere...
To start a system recovery, the best first step is to visit the manufacturer's website (if possible) and download the newest drivers and any firmware upgrades, etc. for your computer. Burn these to a CD, and also include a copy of the latest anti-virus definitions for your anti-virus software of choice. Another really good tool to have are the windows updates. There is a program out there, I forget the name, that will do all the windows updates up to the time you download the program. This makes things easy when you get started up after the recovery.
2. Back up your files. Everything you want to keep, I usually make two backups and test them both on a different computer to make sure that the data is there, or I will back up to an external hard drive.
3. Usually, a recovery Cd-ROM is a bootable media. I have seen a couple of different methods. The most common is that you insert the media into the CD-ROM drive and reboot the system. Just after BOIS posts, you should get a message to press a key to boot from CD-ROM. If this is not the case, you may need to enable booting from CD in the BOIS setup.
the other is that you insert the CD and the program runs in windows and walks you through the recovery.
If you haven't set up Windows before, or if you aren't up to learning by trial and error, I would suggest finding someone experienced to either perform the restore for you or to act as an adviser as you do it. That way, you can have immediate addistance. Also, make sure that you have a computer with internet accessible during the recovery so that if something comes up you can research it and find the answers to your questions.
I hope this helps, good luck!
