I would like to share my experience with the current EOS update. The default boot loader (Systemd) can’t work with this method.
I was trying to dual boot EOS and ReviOS 10. The solution I found for Systemd was:
- Extend the EFI partrition (to 1-2 GB).
- Select that as /efi (Flag boot)
- The rest should be the same as this post.
I’m new to all of this, so I guess this still works with Grub boot loader? Although there are newer posts that say this /boot/efi way is… outdated.
