without grub How can I install both os?
Do I have to change my UEFI settings every time I boot?
You need to add a systemd-boot config entry.
- mount your boot partition on CL with
sudo systemctl start boot.mount
- create a file called
ubuntu.conf
with the following content
title Ubuntu
efi /EFI/ubuntu/shimx64.efi
- copy that file to
/boot/loader/entries
withsudo cp /path/to/ubuntu.conf /boot/loader/entries
- add timeout to boot menu, let’s say 10 seconds with
sudo clr-boot-manager set-timeout 10
- update the boot entries with
sudo clr-boot-manager update
- reboot.
The same is possible for fedora:
$ cat fedora.conf
title Fedora
efi /EFI/fedora/shimx64.efi
I have a platform with Clear Linux, Fedora, and Ubuntu
