Formatting will get rid of the blue screen error and allow you to boot from your Recovery discs to restore the system. I booted from a PowerSuitPro disc and used Partition Magic to format the disk, but you can use any XP or Vista recovery disc. To download Vistas recovery disc go here–>

After I booted from the Restore Disc I discover a second problem. It hung while restoring the system. Got an error code after 24% into the recovery. I headed to HP’s website to order the discs for the PC model I was working with.
