Troubleshooting
Problem
After you upgrade or reinstall QRadar, an error can display when the system attempts to boot with the UEFI boot loader. The host completes a POST successfully, but the boot halts at a blank screen and does not load GRUB as expected. When this issue occurs, the administrator must manually set the boot loader to /EFI/red/grubx64.efi or /EFI/redhat/shimx64.efi. This technical note advises users how to resolve this issue.
Symptom
After an upgrade, one of the following error conditions can occur to indicate you are experiencing a boot loader issue:
- Error message:
The following error occurred while installing the boot loader. The system will not be bootable. Would you like to ignore this and continue with installation?
failed to set a new efi boot target. This is most likely a kernel bug.
Please respond 'yes' or 'no': - The appliance boots and halts at the grub> prompt.
- After POST, the host boots to a blank screen and does not boot Linux GRUB.
