bootctl update question

jesc516 · 2016-09-02 17:01:00

Is there a way to prevent bootctl from searching other operating systems?

Arch is the only operating system on this disk. Im not sure if this correlates with one another but I would like to do a "bootctl update" in order to update the menu entry in my motherboard (I hope this makes sense). Basically when I first installed Arch, the menu entry in my motherboard said "Arch". Now it says "Other OS".

I unplugged the disks in my pc to prevent grub from picking up the other operating systems (on the other disks) when I did a graphical install for another linux distro. Last time I did a graphical install (not for Arch) grub added every operating system in my pc and some entries worked, and others didnt. I would rather use the boot options from the motherboard to select the operating system.

If anyone can point me in the right direction, it will be greatly appreciated.
Thanks

bootctl doesn't search for anything. It will simply add itself to the NVRAM entries, nothing more.

I don't this bootctl is to blame here, the probleme seems more to be from the uefi system itself, not sure though

Please post the output of:

# efibootmgr -v

No, that's the default UEFI loader. You don't have an entry for Arch

you might want to try:

efibootmgr -b 0002 -L "Arch"

I may be wrong but that looks like a firmware-generated NVRAM entry designed to accommodate removable devices that contain UEFI systems.

To generate a new NVRAM entry for systemd-boot you can use:

# bootctl install

However, it may be that your firmware ("BIOS") will "forget" this new entry -- my motherboard does this and I have given up and just use the autogenerated NVRAM entry now.

Just curious, do you know what the data in bold is or where it comes from?

I have to check the motherboard and see if I can add a boot entry manually. I will probably try that. I just know in the past, especially when using graphical installers, they use grub by default so I tend to unplug my other disks to prevent grub from adding them as boot entries. As a result, I end up with the generic UEFI OS entry when I plug back in my disks.

Or, I was thinking about booting to shellx64.efi from "Launch EFI shell from filesystem device" and see if I can remove the UEFI OS and re-add as Arch. Never played with an UEFI shell before.

can i generate one using bootctl install ?

should i try this using a live usb? using this command on the os installed on disk did not work. it just listed the nvram entries.

Arch Linux
