How to enable Network Boot or PXE Boot in BIOS

Updated on Dec 29, 2023 | by Qiling

When to enable Network Boot or PXE Boot

When using Qiling PXE or Qiling Image Deploy, you may need to enter the BIOS settings on client computers and configure them to boot from the network. After Network Boot or PXE Boot is enabled, the client computers can start from the PXE server in your LAN.

To set up client computers in a LAN for network boot, follow the steps below. The example uses GIGABYTE BIOS, but the option names may vary by motherboard or computer model.

Configure PXE boot in BIOS

Enter BIOS:

Start the client computers, and then press the BIOS hotkey. The hotkey is usually F8 or DEL, but it depends on the computer model.

Set boot mode for UEFI BIOS: Click Bios Features -> CSM Support -> Boot Mode Selection. Press Enter on "Boot Mode Selection", and then choose "UEFI and Legacy" or "Legacy Only" in the pop-up window. If your BIOS does not support UEFI, you can skip this step.

Enable the PXE boot (Network boot) option

Use the down arrow key to select "LAN PXE Boot Option ROM", and change its status from "Disabled" to "Enabled". (Note: Network boot is also called PXE boot).

When the computer boots from the PXE network, the network boot screen will appear. The process may take a few minutes, depending on your network speed and the size of the bootable image file.
