I can confirm, that I'm running similar setups with beowulf and pure EFI
boot here. So basically this should be working.

What does "failed attempts" mean here? Did Windows fail to install or
boot? I believe that if Win 10 does not install, then there is probably a
problem in your EFI Bios. Maybe older OS versions don't use some new EFI
feature which is broken on your hardware?

That typically happens when grub does not find its config file. You could
check if the bootloader has been installed successfully:

root@zeus:/home/andi# efibootmgr -v
BootCurrent: 0001
Timeout: 1 seconds
BootOrder: 0001,000B,0002,0008,0003,0004,0005

...


root@zeus:/home/andi# lsblk -o name,partuuid,mountpoint

Did you check that you're using GPT partition table? EFI boot wont work
reliably without that.

My EFI partition is 100M ( 6M used )

Depending on if you use a separate /boot partition, some paths/uuid might
be different.

How did you chroot into your installation? Did you bind mound
/dev, /sys, /proc and related filesystems? Also /boot (if needed) and efi
need to be mounted to get grub properly installed.
