Changing boot order
About this task
You may have to change the boot order if you want to boot from a USB key or an optical drive. The following instructions may
vary if you have selected BIOS for Boot Mode.
Steps
1. On the System Setup Main Menu screen, click System BIOS > Boot Settings > UEFI/BIOS Boot Settings > UEFI/
BIOS Boot Sequence.
2. Click Boot Option Settings > BIOS/UEFI Boot Settings > Boot Sequence.
3. Use the arrow keys to select a boot device, and use the plus (+) and minus (-) sign keys to move the device down or up in
the order.
4. Click Exit, and then click Yes to save the settings on exit.
Network Settings
You can use the Network Settings screen to modify UEFI PXE, iSCSI, and HTTP boot settings. The network settings option is
available only in the UEFI mode.
NOTE: BIOS does not control network settings in the BIOS mode. For the BIOS boot mode, the optional Boot ROM of the
network controllers handles the network settings.
Viewing Network Settings

Steps
1. Power on, or restart your system.

NOTE:
If your operating system begins to load before you press F2, wait for the system to finish booting, and then
restart your system and try again.
