grub-install: error: /boot/efi doesn't look like an EFI partition.

so obviously i had errors with my dual boot system and spent soe time reconfiguring that.  I had to reinstall windows so i moved some partitions around.  In that i had deleted the fat32 partition for artix uefi.  so i saved the other partitions and installed a new artix that now has uefi installed correctly.  And you guessed it, it picks up my configured artix well and windows also.  So booting into the configured artix i now want to install grub and get rid of the new artix as that was my tool for rescuing configured artix that was missing fat 32 uefi.  and so when i try to install grub i get the above error.  what can i do now to install grub into fat32 uefi?  aka /boot/efi??

ok so /dev/sda1 is my linux fat32 uefi partition.
so do i just mount that as /boot/efi
and then install grub?  should i also list it in fstab?

Confused.
If you have an EFI partition that can boot 'new Artix' and 'Old artix" why do you need another EFI partition?

Maybe the two EFI partitions are on different drives ? Hope so because you can't have two on the same the same drive. At least I don't think so? Sounds like trouble.

Are you sure you formatted the newer EFI partition.
What's the output of
Code: [Select]
mount
on the install where you are trying to reinstall grub ?

i can plainly see that my old artix that i am trying to salvage doesn't have an efi at all presently because the file manager shows that i have 18gb free on /boot/efi
i really don't want to keep new artix.  i just did that to avoid chrooting into old artix as it is usually easier.

so clearly fat32 /boot/efi isn't mounted on old artix at all.  i'll copy fstab from new artix for starters i think..

Code: [Select]
UUID=9B8B-E261                            /boot/efi      vfat    umask=0077 0 2
  this is from old artix and that partition doesn't exist. so i'll change the uuid to match new artix and see how that rolls.

ok so using the fstab entry from new artix and placing it in the fstab from old artix and deleting the entry that was listed in old artix seemed to do the trick.
