+If the machine complains about not being able to find a bootable medium, you might need to specify the EFI entry in your BIOS.
+This can be accomplished either by using a live operating system (e.g. Ubuntu) and running the following command (replace `<drivename>` with the appropriate drive name assigned by Linux, typically this will be `sda` or `nvme0n1` on NVMe SSDs):
+
+  ```text
+  efibootmgr --create --disk /dev/<drivename> --part 1 --label "HAOS" \
+     --loader \EFI\BOOT\bootx64.efi
+  ```
+
+Or else, the BIOS might provide you with a tool to add boot options, there you can specify the path to the EFI file:
+
+  ```text
+  \EFI\BOOT\bootx64.efi
+  ```
