Modifying the Boot Order

The boot order list determines which device from which the server boots. To change the order of devices in the boot order list, see the following procedures:

Modify the Boot Order (BIOS)

Access the BIOS Setup Utility.

For instructions, see Using UEFI and the BIOS Setup Utility.
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.
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.
In the Boot Option dialog box, select the device that you want to move into the selected slot.

The device you selected is moved into the indicated slot, and BIOS reorders the remaining devices to accommodate the change.
To save your changes and exit the BIOS Setup Utility, press the F10 function key.

Set Temporary Next Boot Device (Oracle ILOM)

You can use Oracle ILOM to set the next boot device on your server. Setting the next boot device in Oracle ILOM causes your server to boot from the selected device on the next power reset. For subsequent power resets, the server automatically reverts to booting from the boot order list.

Ensure that you have Reset and Host Control (r) role privileges in Oracle ILOM.
To set a once-only boot device for the next power reset in the Oracle ILOM web interface:
1. Log in to the Oracle ILOM web interface.
2. In the navigation pane, click Host Management → Host Control.
3. In the Next Boot Device list, select a boot device.
4. Click Save.
  
  Your selection is only valid the next time the server is powered on. To permanently modify the boot order, see Modify the Boot Order (BIOS).
  
  Note:
  If you select BIOS from the list, next time you boot you do not have to press F2 to access the BIOS Setup Utility.
To set a once-only boot device for the next power reset in the Oracle ILOM command-line interface (CLI):
1. Log in to the Oracle ILOM CLI.
2. Type the set /HOST boot_device command:
  
  -> set /HOST boot_device=bootDevice
  
  Where bootDevice is one of the following: default, pxe, disk, diagnostic, cdrom, bios, or floppy
