I get to the boot options and am not sure what to select. I am trying to multiboot already installed arch and debian .I use refind on my efi. Option systemd-boot I think will blowout My refind so not good. Option refind I think will blowout My refind ,not so good. The last option (no boot loader) will not provide the efi/kaos/?.efi for booting with My refind. How do I manage it? I also select /boot/efi ( I add the /efi) instead of /boot in the install to say where the the boot loader is to be placed. What do I change to get kaos install to boot?
You can use rEfind as an option during the install, it adds all other systems, regardless of location, or use no bootloader and update your existing rEfind to have it add KaOS.
