Sorry for not replying sooner. The reason is because if I post a reply in a thread I'm helping in and the OP doesn't reply after 4 days, I unsubscribe from the thread. I carry too many threads to keep all subscriptions.
This tells me that during boot, Windows is trying to boot off the hard drive. Did you change the boot sequence in bios to have the computer boot from the CD/DVD drive?
Windows could not start because the following file is missing or corrupt: \WINDOWS\system32\config\SYSTEM
As the computer boots up, try tapping the ESC key to see if you can access the boot menu. If a menu comes up and the CD drive is listed, have the computer boot from it... be sure you have the Windows CD in the drive before attempting this. If the CD boots, try running Windows repair as described in the link I posted.
If you don't get the boot menu, then you may need to go into bios to change the boot order. According to the DV2000 manual, you need to depress the F10 key (continually tap the F10 as the computer boots). Once in bios, you will need to look through the menus to find/change the boot order to the CD/DVDROM.
