Red screen error on iLO console due to bad OS boot entry

Symptom

A red screen error appears on the iLO console of the server because of a bad entry in the OS boot.

Cause

The probable cause is that the OS was deleted but the UEFI boot entry still exists. Even after deleting the bad OS boot entry from the UEFI boot options, this error may still persist.

Action

To clear the BIOS array, perform the following steps:

  1. Log in to iLO of the respective server.
    NOTE:

    The iLO Administrator user credentials are available in your input JSON file.

  2. In the iLO Overview window, select the Integrated remote console and click .Net.
  3. In the Application Run window, click Run.

    The iLO Integrated remote console window appears.

  4. To reboot the server, select Reset from the Power Switch drop-down menu.

    After the successful reboot of the compute node, the Power-On-Self-Test (POST) screen appears.

  5. To view the System Utilities window, press F9.
  6. Navigate to System Configuration > BIOS/Platform Configuration (RBSU) > Boot Options > UEFI Boot Settings > UEFI Boot Order Control.
  7. Clear the check box corresponding to the bad OS boot entry.
  8. Save the changes and restart the server.
