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

From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

What version of Ubuntu are you using?
What is the output of the following command?:
dpkg -l | grep grubIf you urgently want your grub menu to default to the first entry that can be done first, but unless that's needed I'd prefer to get to the root of the problem(s) and get a proper fix.
I'm using 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/cmdlineAnd 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).
This command doesn't work for me
