HAL.DLL is Missing or Corrupt (Windows Embedded Standard 2009)
Learn what to do when you receive this error message.
Be sure that you copied Boot.ini, Ntdetect.com, and Ntldr from your run-time image to the root directory of your target system's boot drive. Be sure as well that you overwrote prior versions of these files.
Be sure that you added a HAL in your configuration.
If a HAL was added, remove it from your configuration, and then add the HAL again.
