So far, so good. However, please show us the complete command and output by copy and paste. E.g.: root@peregrine:~# grep efi /etc/fstab # /boot/efi was on /dev/nvme0n1p1 during installation UUID=91AE-3A24 /boot/efi vfat umask=0077 0 1 root@peregrine:~# df -h /boot/efi/ Filesystem Size Used Avail Use% Mounted on /dev/nvme0n1p1 93M 5.9M 87M 7% /boot/efi root@peregrine:~# For example, the output I show confirms that the correct partition is mounted on /boot/efi. > But I also find the directory > > /efi > > which has the same content as /boot/efi.

I can tell you that I have several UEFI machines here and not one of them shows it. How did you install your system? Which distribution? I used a Debian netinst installer to install all of mine. You didn't tell us what distribution of Linux your are using; for all I know you are using some distribution that creates /efi for you. > > 2. If not, how can I get rid of it? That depends on what it is. If it is a regular directory, then "rm -r /efi" should do it. However, if your EFI partition is also mounted on /efi, or /efi is a symbolic or hard link to /boot/efi, that would be catastrophic. > > 3.

If you used a Debian 12 (bookworm) netinst installer, you should have everything you need. For most people, grub and efi are "fire and forget" systems: the system is set up once and runs automatically as needed. > > Thanks for enlightening me! > > Best > > Hans -- Does anybody read signatures any more? https://charlescurley.com https://charlescurley.com/blog/
