Looking for a way to start the firmware via UEFI boot menu?

nursoda · 2022-01-31 00:38:21

The UEFI firmware of a notebook I just installed does not provide a "Start BIOS/firmware" entry. Lenovo Laptops do provide that (and one even cannot disable it, it's added by the firmware itself). Now, since the other notebook does not provide such entry – is there a way to manually add it using efibootmgr? How would the parameters would look like? Is there a "default path" like magic word to start a system's firmware? Any idea appreciated.

And, yes, I can access the firmware using `systemctl reboot --firmware-setup`. That's not what I'm asking for.

What is this "Start BIOS/firmware" option supposed to do ?

Depending on the notebook model, isn't there a key sequence you can press at startup to achieve that?

I think he wants to enter into the bios/uefi. That is, be able to read, and change, the settings of the system. Though I would have expected him to answer your question.

@regid, that's not what he meant, well partially.
The use of one of the function keys 'F1 - F12' is valid, one of those will most likely enter the firmware - before the distro boot menu is started.

What he wants is an entry in the 'boot menu' to start the 'UEFI firmware' or BIOS if you like:-)
You can't because the 'distro boot menu' is released by the firmware.
So if there would be such entry, you'd need to first reboot than start the firmware entry.
To add that with 'efibootmgr' is not possible, far as I know.
You would need to have a machine/chip! where that's already backed into, correct me if I'm wrong!

grub does that by default:

or on most laptops you can press either f1, f2 to enter bios/uefi or f11, f12 for boot selection menu which has an option for bios/uefi.

pretty standard stuff

Thanks for adding that info, I really didn't know you could add that to the 'boot menu'
Not a grub user either, I simply use the function keys...

That's not what nursoda was asking.....
OP was after a NVRAM entry with the same functionality as I'm presuming they don't use a bootloader.

That's why I asked for clarification .
