In the simplest form, running `sbctl reset` returns the following:
could not reset PK: couldn't write efi variable: write /sys/firmware/efi/efivars/PK-8be4df61-93ca-11d2-aa0d-00e098032b8c: input/output error
I checked the folder and this file doesn't exist, however a similar file does exist called `PKDefault-8be4df61-93ca-11d2-aa0d-00e098032b8c`, but I'm not sure if it's related.
sbctl status
confirms I'm in setup mode.
The reason why I'm resetting is due to a BIOS update that no longer recognized grub, which after fixing broke my secure boot setup.
Is there any way to resolve this? Any help appreciated.

not using secureboot - as in: what does secureboot protect against anyway?
in its most basic form all it ensures is that the bootcode has to result in a hash that's known to the firmware - that's it ... and it ain't much
sure, this COULD be extented - but as far as I'm aware only to the kernel and initrd the bootcode loads and start ...
... and from there? neither windows nor linux enforce this chain any further into userland: you can still download any stuff from the internet or even write your own - and there's nothin stopping you
and even if: it's your system, you're the admin and if required you can grant execution permission to everything
so - against what exactly does secureboot protect you?
unless you can give any answer to this I wouldn't bother with this crap - just wipe the keys and use your computer as you like

I'm dual booting with Windows 11 and play games with kernel level anticheats and ones that require secure boot. I don't want to have to switch between them each time I switch OSes.
