My grub boot partition belongs to another Linux install and I want to get it back.

It appears you have done a re-install. You now have two efi partitions, only need /dev/nvme0n1p1.
During the re-install is there a reason you kept the /dev/nvme0n1p3 partition?
Hi,
I have done a few reinstalls of the second Mint copy, which is now on p3, as it detects the original (main) version of Mint and adds it to grub. This is the only way I have been able to create a boot partition that allows me to choose to boot into my main install.
I've edit the theme cfg file as suggested in that post. And when I run
Code:
sudo dpkg --configure -a
, I get no message, just a new prompt.
When I run
Code:
sudo grub-install
I get :
Code:
Installing for x86_64-efi platform.
grub-install: error: cannot find EFI directory.
And when I run
Code:
sudo update-grub
I get:
Code:
Sourcing file `/etc/default/grub'
Sourcing file `/etc/default/grub.d/50_linuxmint.cfg'
Sourcing file `/etc/default/grub.d/63_mint-theme-2k.cfg'

Not necessary, but will prevent failure if there is grub package upgrade, create a mount point for the efi partition in /etc/fstab similar to the previous fstab.

I'm not sure what you are doing but originally, you indicated your 'new' install of Mint was on partition three and your 'old' install was on partition 5. Your most recent boot repair doesn't even show a partition 5. What happened there? You show a Linux partition on partition 2 now?
The UUID for partition 2, according to boot repair, is 0ca5353e-55f2-4bde-85a3-4183a5361c2d which is what partition 5 originally showed so if that is the partition you want booting, you need to go into the grub.cfg file on the EFI partition and change your UUID there to the one for partition 2. Do as root, save and reboot. The current UUID in that file is 'b5b94bdb-d97d-48d0-8f30-bcedf470b919' which is partition 3 that you indicate is the new install. Have you already made this change? Did you run the update-grub command from partition 2, the original install?
Might this have something to do with LVM? Did you do both installs LVM? I don't use it but many others here so.

Many thanks colorpurple21859!! That seems to have done the trick!

Hi Yacek,
Yeah, 0ca5353e-55f2-4bde-85a3-4183a5361c2d is the main Linux install and it now has control of grub. I don't think this was an LVM issue, I think it was connected to removing fonts or something like that.
Anyway, seems to be ok now. Thanks very much for your help and advice!
