HP Notebook PCs - "Non-System Disk Error or Disk Error" Error Message Appears On Black Screen
This document pertains to HP Notebook PCs with Windows Vista.
Understanding Non-System Disk Errors or Disk Errors
The Non-System Disk Error or Disk Error error message may appear when the computer BIOS cannot find a bootable operating system on any of the storage devices included in the notebook PC's boot path.
During startup, a notebook checks several devices for an operating system in a pre-determined order. You can change the order of the search by changing the Boot order in the system BIOS.
Use one or more of the methods to resolve what are called boot errors or black screen error messages that may occur before Windows Vista starts.
If you receive either of the error messages and are instructed to test the hard drive by pressing F2 , please see HP Notebook PCs - Boot Device not Found for additional instructions. However, if the F2 option is not presented, then continue with the instructions in this document.
Use one or more of the following methods to resolve a boot error or black screen non-system disc error. Different models and different BIOSs may present different methods for accessing the hard drive diagnostic tests.
Remove the non-system disk from the computer
Because the boot order can be changed, it is possible that the computer is accessing a non-operating system disc in the floppy disc or CD/DVD optical drive. Use the steps below to remove all non-system disks and reboot a notebook PC.
If the computer boots properly after the non-system disc was removed, you should reset the default boot order in the BIOS as shown in the next method.
Resetting the boot sequence
For most models, you can press the F10 key during startup to access System Configuration , and select Boot Options , then Boot Order , to view your boot sequence. To change the sequence to the default settings, press F9 and Yes to load Setup Defaults.
Test the hard drive
Many PC startup problems are caused by minor errors in the software that controls the storage of files on the hard drive. The HP Hard Drive Self Test will detect and repair these errors but will not produce a detailed report of all the actions taken. For the test to run, there must be good physical connection between the hard drive and the computer. If the computer is dropped or jarred, the hard drive may moved and disrupted the connection, and that will cause the test to fail or may even prevent the test from starting.
You may want to try running the HP Hard Drive Self Test, but if it fails, see the section on Removing and Reinstall the Hard Drive, and then repeat the Self Test.
Use the steps below to test the hard drive for errors by using the HP Hard Drive Self Test.
The self test process may include both a Quick test and a Comprehensive test. It also provides an Estimated test time .
After the Hard Drive Self Test is complete, restart the PC to verify that the problem is repaired.
Removing and Reinstalling the Hard Drive
If the computer was dropped or jarred, you may have to remove and reinstall the hard drive before running the HP Hard Drive Self Test.
CAUTION: To prevent damage to you computer, it is necessary to remove the battery prior to removing the hard drive.
Reinstalling the Windows operating system on the hard drive
If removing non-system disks and performing an HP Hard Drive Self Test does not resolve the boot errors or black screen error, it may be necessary to reinstall the Windows Vista operating system (OS). You can reinstall the operating system by either:
