I have multiple Linux distros installed on my system (Gigabyte GA-H97M-D3H mobo, SSD as sda and HDD as sdb) any of which I can boot via rEFInd. Recently I decided to add Xubuntu 18.04 LTS. The problem is that after installing, rEFInd does not find it and offer it as a boot option. All the other distros (i.e., Linux Mint, Kubuntu, and Ubuntu) are still there and boot OK so I am thinking there is something unique about how the Xubuntu installer sets things up. I've reinstalled it from scratch several times, switched the partitions around, etc. Nothing seems to make a difference.
Is there something I am missing or is there a basic incompatibility between rEFInd and Kubuntu? All distros are, as far as I can tell, being set up the same way (i.e., installed on a partition on the sda drive).
UPDATE: It has been suggested (by kc1di) that the order of installation matters and that the xubuntu install is being presented by rEFInd as an ubuntu entry. That does not seem to be the problem as I tried installing in different orders but nothing changed. I also removed the ubuntu distro entirely. At the moment my set-up is (in order of installation):
- Linux Mint 17 with KDE
- Linux Mint 19.1 with Xfce
- Xubuntu 18.04
The Xubuntu entry is still missing from the rEFInd menu.
