Ok where can I find instructions to do that?
BTW I see that I have 5.10 installed, but Manjaro doesn’t say it’s the recommended kernel. I just go with what Manjaro decides is current/recommended.

Oh do you mean backup and reinstall Manjaro or just Grub?
FTFY. You might not get a lot of sympathy for using that. Have a gander on the archived forums to get a feel about what a lot of folks here feel about it.
Well I won’t anymore, I’m just trying to undo the damage. Is there a safe way to uninstall and reinstall grub while Manjaro is running? Like I said, I can get in so I don’t need a boot CD.
grub can be installed via
sudo -Syu grub
You also should use “grub-install”, but you need to find out the right syntax for your specific system:
https://wiki.manjaro.org/index.php?title=GRUB/Restore_the_GRUB_Bootloader
Nevertheless, no guranatees that this will fix all issues GC could have caused.
If you want to get rid of any trace of grub customizer:
# Remove all grub configurations
sudo rm /etc/default/grub
sudo rm /etc/grub.d/*
# Reinstall grub
sudo pacman -S grub
# Recreate grub config:
sudo update-grub
You can do it in your live system. There is no problem at all.
Note: This is going to remove also any custom modification you may have. So be advised…
The only custom modifications I did are wallpaper and colors which I can either redo or do without. I assume this will also find my Windows 10 partition?
Yes, If there is nothing odd in your installation, update-grub should find your Windows also
If you want to take benefit from latest security mitigations don’t forget to consider “grub-install”.
Ok I ran those commands and it said it installed correctly. How do I use grub-install? did removing those files also remove the bootloader? Do I have to reinstall it with grub-install? How can I tell where it’s currently installed (or if it is)?
Please post
inxi -Fxxxza --no-host
sudo parted -l
sudo efibootmgr -v
test -d /sys/firmware/efi && echo efi || echo bios
Then we might suggest a syntax for grub-install.
These can be done in themes such as seen in /usr/share/grub/themes
Or the basics can be done right in the config file /etc/default/grub
:
# Uncomment and set to the desired menu colors. Used by normal and wallpaper
# modes only. Entries specified as foreground/background.
GRUB_COLOR_NORMAL="light-gray/black"
GRUB_COLOR_HIGHLIGHT="green/black"
# Uncomment one of them for the gfx desired, a image background or a gfxtheme
#GRUB_BACKGROUND="/usr/share/grub/background.png"
GRUB_THEME="/usr/share/grub/themes/manjaro/theme.txt"
(always remember to run sudo update-grub
after making changes to config)

I just formatted your post a bit to make it more legible, hope it’s OK for you.
You have several disks, so it’s more safe if you could also provide output of
cat /etc/fstab
mount
Oh that’s fine. BTW I found a script that said it could find where GRUB was installed. Unfortunately it found it on three of four drives. Which one’s the real one?
cat /etc/fstab
# /etc/fstab: static file system information.

# Use 'blkid' to print the universally unique identifier for a device; this may
# be used with UUID= as a more robust way to name devices that works even if

OK, you need to execute
sudo grub-install /dev/sdb --recheck
Afterwards run
sudo update-grub
Make sure to boot into your BIOS and select the disk sdb (could have a different name there) as your new boot disk.
P.S.: Next time, please format the code as I changed it.
Ok, wish me luck. If I don’t reply in a few minutes I guess something went wrong (thankfully I have a laptop too I can use to get help if that happens).
BTW I think this makes sense as sdb is my main Linux drive and sdc is my main Windows drive. sda and sdd are storage drives for Windows and Linux respectively.
Looks like all is good!
Thanks for the help everyone I really appreciate it!
