Unable to install EndeavourOS (dual-boot with W11)

[Gumaa]

So I have a problem with installing EndeavourOS:
https://termbin.com/dh1l

I have two SSDs:

1. 500GiB with Windows
2. 1000GiB with data and spare 150GiB reserved for EOS

I tried couple of partitioning approaches, but nothing seem to work. Latest attempt was using manual partitioning approach, because as described in this thread: Does Endeavour installer is trying to create EFI partition on my USB stick? - #6 by Gumaa , I encountered a bug in the installer, where automatic options like replacing a partition do not work and do not create EFI partition.

So I manually created two partitions:

1. EFI partition fat32 with 1GiB, mounted to /efi and flagged as boot
2. Root partition with ex4 with rest of the space, mounted to / and flagged as root

But it didn’t work. I’m unable to pin point what is wrong looking at the logs.
There is this error:

ERROR: Error while running: FileNotFoundError: [Errno 2] No such file or directory: ‘/tmp/calamares-root-1qb4ipel/efi/loader/loader.conf’

but also beforehand there is a warning:

WARNING: [PYTHON JOB]: “Failed to mount foreign EFI dir”

So maybe I did something wrong while partitioning?

Also installer as a whole seems really buggy. Often when I’m choosing partitioning type (eg. replace, alongside, manual) or when clicking on a partition to replace the whole installer just closes and I have to start from the scratch.

Btw, why EFI should be mounted to /efi? Arch wiki is saying it should be /boot. Is there some specific configuration needed for EOS? Also I saw in couple of places that people were saying it should be /boot/efi? But maybe this information is outdated.

Ok, I was able to install EOS.
I tried the same approach (meaning manual partitioning) but this time with Grub instead of systemd. And it worked!

Not sure why, but after choosing Grub I was able to mount EFI partition to /boot/efi, while previously it was /efi ¯\(ツ)/¯ Probably it is supposed to work like this and it is a difference between Grub and systemd, but I’m a noob so I don’t know.

Also I had to reboot the machine, because after my previous attempts the partitions were kinda stuck, and I couldn’t do anything with them, format, shrink, delete. After I rebooted the PC I was able to free the space one more time, then I went with the steps described in the question.
