Resolving an operating system boot failure

Learn how to identify the service action that is needed to resolve a failure while booting your operating system.

Procedure

  1. Was the system recently installed, serviced, moved, or upgraded?
    If Then
    Yes: Ensure that all cables are properly seated in the connection path to the designated boot device. This ends the procedure.
    No: Continue with the next step.
  2. Petitboot displays all recognized bootable images to use by default. Is the boot image recognized by Petitboot?
    If Then
    Yes: Continue with the next step.
    No: Select the Petitboot menu option to refresh the boot images. If the problem persists, go to Resolving a storage device problem. This ends the procedure.
  3. Does an operating system error occur during the boot?
    If Then
    Yes: Recover the operating system with the tools provided for the operating system. If that does not resolve the problem, reinstall the operating system. This ends the procedure.
    No: Reinstall the operating system. This ends the procedure.
