If you miss the window to press the key, you will need to shut down the laptop and try again.

Modifying Boot Order Settings

Once you are inside the BIOS/UEFI setup utility, your primary goal is to change the boot order so that the laptop attempts to boot from your USB drive before other storage devices like the internal hard drive. The exact location and naming of these settings can vary slightly between different Dell models and BIOS/UEFI versions.

Here are the general steps to locate and modify the boot order:

Navigate through the BIOS/UEFI menus using your keyboard’s arrow keys. The keys for navigation (e.g., Enter to select, Esc to go back) are usually displayed at the bottom or side of the screen.
Look for a section typically labeled “Boot,” “Boot Sequence,” “Boot Order,” or “System Configuration.”
Within this section, you will find a list of boot devices. Your goal is to move the USB drive (it might be listed as “USB Storage Device,” “Removable Devices,” or by the specific name of your USB drive) to the top of this list.
The method for reordering devices varies: some BIOS/UEFI interfaces use the ‘+’ and ‘-‘ keys, others use the F5 and F6 keys, and some allow you to drag and drop items if a mouse is supported. Consult the on-screen instructions for the specific key combinations.
Once the USB drive is set as the first boot device, navigate to the “Exit” or “Save & Exit” section.
Select the option to “Save Changes and Exit” or “Exit Saving Changes.” Confirm your choice when prompted.

After exiting the BIOS/UEFI, the laptop will restart, and if configured correctly, it should attempt to boot from your USB drive.
