I’m trying to update my grub boot order back to booting the first option instead of the second, so I run sudo nano /etc/default/grub
, but it brings up this, which is not the file I want to edit.
I’m on fedora 38

Ahh, sorry.
For Fedora it looks like the default /etc/default/grub looks like this:
GRUB_TIMEOUT=5 GRUB_DISTRIBUTOR="$(sed 's, release .*$,,g' /etc/system-release)" GRUB_DEFAULT=saved GRUB_DISABLE_SUBMENU=true GRUB_TERMINAL_OUTPUT="console" GRUB_CMDLINE_LINUX="rhgb quiet" GRUB_DISABLE_RECOVERY="true" GRUB_ENABLE_BLSCFG=true
( Taken from https://discussion.fedoraproject.org/t/how-to-regenerate-etc-default-grub/72677/9 )
If you’re using LVM / LUKS you may need additional kernel parameters, like resume=… for suspend to disk to work properly.
Please, before doing anything else, post the output of the following:
cat /proc/cmdline
And make a backup of your existing grub.cfg with:
sudo cp /boot/grub2/grub.cfg /boot/grub2/grub.cfg-backup-$(date --iso=s)
Also, be sure that you have a LiveUSB on hand. You don’t want to be SOL if we break something and can’t boot again without fixing it first.
