Generally the boot sequence would be CD/DVD drive first and then the hard drive. But this infinite loop problem is most likely caused by a virus. Try this:
Insert the Windows XP CD into the CD drive, and then restart the computer. Click to select any options that are required to start the computer from the CD drive if you are prompted. When the "Welcome to Setup" screen appears, press R to start the Recovery Console. If you have a dual-boot or multiple-boot computer, select the installation that you must access from the Recovery Console. When you are prompted, type the Administrator password. If the administrator password is blank, just press ENTER.
Type: chkdsk /r
It's important to have a space before the "/".
To exit the Recovery Console and restart the computer, type exit at the command prompt, and then press ENTER.
The power of accurate observation is commonly called cynicism by those who haven't got it.
