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.

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. Are you booting the operating system from a network location?

   If	Then
   Yes:	Continue with the next step.
   No:	Continue with step 4.

3. Complete the following actions, one at a time until the problem is resolved:
   1. Ensure that a problem does not exist with the connection to the network location.
   2. Ensure that the adapter has a valid IP address for the network.
   3. Replace the network adapter.
      • If your system is an 8335-GTC, 8335-GTG, 8335-GTH, 8335-GTW, or 8335-GTX, go to 8335-GTC, 8335-GTG, 8335-GTH, 8335-GTW, or 8335-GTX locations to identify the physical location and the removal and replacement procedure.
4. 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.

5. 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.
