Modifying the Boot Order
Secure Boot also requires all third-party UEFI drivers and operating system boot loaders to
be signed by Microsoft or with Key Exchange Key (KEK) by using BIOS Setup Utility.
Trusted Execution Technology and UEFI Secure Boot are disabled by default. For configuration
information, refer to your server service manual.
Modifying the Boot Order
The boot order list determines which device the server boots from. You can make persistent
changes to the boot order list in the BIOS Setup Utility, or you can specify a boot device that is
only valid for one subsequent server boot in Oracle ILOM.
If you enable the Persistent Boot Support feature, every physical slot, network port, and disk
drive bay in the server is shown in the boot order list. For more information about Persistent
Boot Support, see “Enable Persistent Boot Support (BIOS)” on page 50 .
To change the order of devices in the boot order list, see the following procedures:
■
“Modify the Boot Order (BIOS)” on page 48
■
“Set Temporary Next Boot Device (Oracle ILOM)” on page 49
Modify the Boot Order (BIOS)
1. Access the BIOS Setup Utility.
For instructions, see “Accessing the BIOS Setup Utility” on page 34 .
2. Navigate to the Boot menu.
The Boot Option Priority list shows the current boot order from top to bottom. For example, the
first device in the list indicates the first boot option.
3. In the Boot Option Priority list, select the device in the boot option slot you want
to modify.
For example, if you want to move a device to the second slot, select the second item in the list.
The Boot Option dialog box appears.
4. In the Boot Option dialog box, select the device that you want to move into the
selected slot.
