Recovering Boot Options in System Setup

When the BIOS is recovered or updated, the system setup options are reset to the default

options. Before performing a BIOS recovery, write down the current configuration settings

so that you can restore the settings. The following sections give information on how to use

the EFI Boot Manager and how to reinstall boot options with the Windows and Red Hat

Linux operating systems.

The EFI Boot Manager menu allows you to access the operating systems installed on your

system, a Boot option maintenance menu, and the EFI shell.

Turn on your system by pressing the power button on the system's front panel.

If your system is already on, reboot it.

Wait until the system tests are completed.

The EFI Boot Manager screen appears.
