At the moment, NixOS/Clan does not support [Secure Boot](https://wiki.gentoo.org/wiki/Secure_Boot). Therefore, you need to disable it in the BIOS. You can watch this [video guide](https://www.youtube.com/watch?v=BKVShiMUePc) 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.
