When I turn my pc on, I see a black screen that tells methat windows cannot start because the file <windowsroot>\system32\hal.dll. is missing or corrupt. I went into Bios and changedthe boot order so the CD is first on the list. However, when I insert myrecovery disc, I get the option of pressing R for recovery. But when I do that,the Compaq logo comes on for a few seconds, but then I get a blue screen that aproblem with windows has been detected. It Says PAGE_FAULT_IN_NONPAGED_AREA. Itnever gets to recovery.
