This is a brief guide to configure the BIOS settings on Dell machines. If your machine is not a Dell, has different options, is missing options, or is a Dell 7400 or XPS model, please consult the Help Desk.
IMPORTANT NOTE: Altering BIOS settings is risky. Changing settings without guidance can cause the system to not boot properly.
Always consult the Help Desk first. We'll walk you through the steps over the phone (in-person if we are on site) if you are new or feel uncomfortable with the process.
How to access BIOS settings:
- Plug in both the power and the Ethernet/network cable to the computer that is getting imaged.
- Press the power button to turn on the computer and immediately start rapidly tapping the F12 key. The Dell splash screen will display and you should see text in the upper right corner: “Preparing one-time boot...”
- A boot menu will appear. Use the arrow keys and press enter once BIOS Setup is selected.
BIOS Settings to Adjust:
You'll see a grey window with a menu navigation pane on the left, and the options for each of those menu options will appear on the right as you navigate through the menu. Different models may look different and have slightly different options (or have options missing) - please check with the Help Desk if you have any questions.
