Johannes Kirschbauer 8097d491cd docs: remove step numbers
Numerating steps is not informative and considered bad style
People tend to follow documentation non-linearly
leaving of at one point, starting over from the middle
Documentation should be written in a way that allow for that

At the moment, NixOS/Clan does not support Secure Boot. Therefore, you need to disable it in the BIOS. You can watch this video guide or follow the instructions below:

Insert the USB Stick

  • Begin by inserting the USB stick into a USB port on your computer.

Access the UEFI/BIOS Menu

  • Restart your computer.

  • As your computer restarts, press the appropriate key to enter the UEFI/BIOS settings. ??? tip "The key depends on your laptop or motherboard manufacturer. Click to see a reference list:"

    Manufacturer UEFI/BIOS Key(s)
    ASUS Del, F2
    MSI Del, F2
    Gigabyte Del, F2
    ASRock Del, F2
    Lenovo F1, F2, Enter (alternatively Fn + F2)
    HP Esc, F10
    Dell F2, Fn + F2, Esc
    Acer F2, Del
    Samsung F2, F10
    Toshiba F2, Esc
    Sony F2, Assist button
    Fujitsu F2
    Microsoft Surface Volume Up + Power
    IBM/Lenovo ThinkPad Enter, F1, F12
    Biostar Del
    Zotac Del, F2
    EVGA Del
    Origin PC F2, Delete

    !!! Note Pressing the key quickly and repeatedly is sometimes necessary to access the UEFI/BIOS menu, as the window to enter this mode is brief.

Access Advanced Mode (Optional)

  • If your UEFI/BIOS has a Simple or Easy mode interface, look for an option labeled Advanced Mode (often found in the lower right corner).
  • Click on Advanced Mode to access more settings. This step is optional, as your boot settings might be available in the basic view.

Disable Secure Boot

  • Locate the Secure Boot option in your UEFI/BIOS settings. This is typically found under a Security tab, Boot tab, or a similarly named section.
  • Set the Secure Boot option to Disabled.

Change Boot Order

  • Find the option to adjust the boot order—often labeled Boot Order, Boot Sequence, or Boot Priority.
  • Ensure that your USB device is set as the first boot option. This allows your computer to boot from the USB stick.

Save and Exit

  • Save your changes before exiting the UEFI/BIOS menu. Look for a Save & Exit option or press the corresponding function key (often F10).
  • Your computer should now restart and boot from the USB stick.
