Booting from an Alternate Boot Source

There are times when you will need to boot from a device other than the

device that you normally boot from. For example, if your primary boot

disk fails, you will need to boot your system either from a different disk

or from a recovery tape.

Booting from an Alternate Boot Device You can boot from an

alternate device in following ways. If your system is set up to

automatically boot you will need to override the autoboot sequence by

hitting any key on the console keyboard during the autoboot delay

(time-out) period.

❏ If the alternate device that you want to boot from is listed in the boot

options menu (the main EFI Boot Manager menu), use the arrow

keys to highlight the entry for the alternate device and press Enter on

the keyboard to boot from that device

❏ If the alternate device that you want to boot from is not listed in the

boot options menu:

Step 1. Select “EFI Shell [Built-in]” from the boot options menu to run the

EFI shell.
