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-8601=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.

        Sorry again. I wrote this last comment (and this one, TBH) from my phone and “–iso=s” should have been “–iso-8601=s” . I’ve edited my comment and the command should now work (Making a backup of your grub.cfg containing the date, to the second, in the filename. I did that to hopefully avoid you running the same command again after trying some fixes and accidentally clobbering your backup).
