|
This is efibootmgr, a Linux user-space application to modify the Intel
|
|
Extensible Firmware Interface (EFI) Boot Manager. This application can create
|
|
and destroy boot entries, change the boot order, change the next running boot
|
|
option, and more.

--[003] Mounting The efivar Filesystem -----------------------------------------
|
|
|
|
To use efibootmgr and other software to manipulate the UEFI boot entries, the
|
|
efivars filesystem must be mounted. This isn't handled automatically by KISS
|
|
due to the security implications in doing so. [1]
|
|
|
|
+----------------------------------------------------------------------------+
|
|
| |
|
|
| $ mount -t efivarfs none /sys/firmware/efi/efivars/ |
|
|
| |
|
|
+----------------------------------------------------------------------------+
|
|
|
|
|
|
--[004] Booting The System With An EFISTUB -------------------------------------
|
|
|
|
Using an EFISTUB to boot the system removes the need for a bootloader and
|
|
shortens boot times. Ensure that the following options are enabled in your
|
|
kernel: CONFIG_EFI, CONFIG_EFI_STUB
|
|
|
|
Run the following command to create a boot entry (replacing example arguments
|
|
with their respective values). X and Y should point to where the ESP is
|
|
located.
|
|
|
|
+----------------------------------------------------------------------------+
|
|
| |
|
|
| $ efibootmgr \ |
|
|
| --disk /dev/sdX \ |
|
|
| --part Y \ |
|
|
| --create \ |
|
|
| --label "KISS" \ |
|
|
| --loader /vmlinuz \ |
|
|
| --unicode 'root=PARTUUID=XXXXXXXX-XXXX-XXXX-XXXX-XXXXXXXXXXXX rw' \ |
|
|
| --verbose |
