Choosing the system boot mode

System Setup enables you to specify one of the following boot modes for installing your operating system:

• BIOS boot mode (the default) is the standard BIOS-level boot interface.

• Unified Extensible Firmware Interface (UEFI) (the default) boot mode is an enhanced 64-bit boot interface. If you have configured

your system to boot to UEFI mode, it replaces the system BIOS.

1. From the System Setup Main Menu, click Boot Settings, and select Boot Mode.

2. Select the boot mode you want the system to boot into.

CAUTION: Switching the boot mode may prevent the system from booting if the operating system is not installed in

the same boot mode.

3. After the system boots in the specified boot mode, proceed to install your operating system from that mode.

NOTE: Operating systems must be UEFI-compatible to be installed from the UEFI boot mode. DOS and 32-bit operating

systems do not support UEFI and can only be installed from the BIOS boot mode.

NOTE: For the latest information about supported operating systems, go to Dell.com/ossupport.

Changing the boot order

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.

2. Click Boot Option 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 PXE device settings. The network settings option is available only in the UEFI mode.

NOTE:

The 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.
