No bootable device, hit any key

I’m an idiot. I’m also pretty new with this whole linux thing. I was tinkering about with systemd, and decided to check out the bootloader options. For some unexplicable reason i turned off secure boot, so now i can’t boot into openSUSE at all and get this message. I was thinking of booting up a live distro, and just manually turn secure boot on again, but i’m not sure where to look for the option. Can someone please assist :’(

P.S. I was using UEFI, and it’s openSUSE 13.1 if i’m not mistaken

Can you boot from the install DVD okay? Perhaps that will allow you to gain access to the installed OS.

Otherwise consider disabling secure boot from UEFI if possible.

This could mean:

(1) You disabled secure-boot in the BIOS;

(2) You changed the grub2-efi boot configuration to disable secure boot.

Doing (1) should be harmless. Your system should still boot.

If you did (2), then also doing (1) should make the system bootable again.

There’s another possibility, but it does not fit your description. Maybe you switched your BIOS to legacy boot (instead of EFI boot). That isn’t what you described, but it might cause the problems that you are having. You would need to go to BIOS settings to switch back to UEFI.

At this stage, we could use some more clarification on what you think you did.

Oh, and don’t worry about looking like an idiot. We just need the information to try to help.

Im currently not near my laptop so i cant do anything (i will get back home later today), but i am certain of the following.

My bios is set to efi boot, and i cant turn off the secure boot option in the bios (it is greyed out)

The option i changed is in the bootloader options in opensuse.

I will try booting from live cd when i get home

That’s odd. Microsoft assured us that their requirements included the ability to turn off secure-boot (unless this is ARM hardware).

The option i changed is in the bootloader options in opensuse.

That would explain your problem.

Unless you can disable secure-boot, your only option is to boot from live media, and go into rescue mode. There you will need to reinstall the boot loader with secure boot support.

Apparently you have to set up a BIOS (or “Supervisor”) password on certain systems to be able to turn off secure boot.

Did this (set up a supervisor password) and managed to turn off the secure boot, but the system still didn’t boot up. I just decided to back up the data and format/reinstall it. Next time i will research options before setting them off or on :stuck_out_tongue:

Thank you all for your help tho. Seems like a good community. I will definitely stick around and learn the system.
