HP Notebook PCs - "Windows Unsafe or Sudden Shutdown" Blue Screen Error Occurs During Startup or Boot

Description
Windows XP may not start and the following error message may appear on a blue screen:
Windows Unsafe or Sudden Shutdown
This error occurs after Windows was not shutdown using a safe method. The notebook may have been turned off without clicking Shut Down or briefly pressing the computers Power button. The power may have been suddenly disconnected from the computer or the Power button may have been held for more than 5 seconds.
An unsafe shutdown can damage some of the Windows system files, preventing the computer from starting properly.
Solution
If the error occurs allow the operating system to complete a check of the hard disk. Windows will prompt your to run CHKDSK. CHKDSK scans the hard drive for damaged files and repairs the files if necessary. The scan may take up to an hour depending on the size of the hard drive and the number of damaged files. The computer will restart when the scan is complete and Windows should start normally.
If Windows will not start or the computer will not boot after the scan is complete see: HP Notebook PCs - Troubleshooting a Startup or No Boot Problem (In English)
