You should also have screen for UEFI somewhere or perhaps under the Harddrive setting. Most either have a sub menu under hard drive or have another UEFI/BIOS screen with more boot options. Your f12 Ubuntu entry says it is the UEFI entry but that probably is just a one time setting, you have to change it in UEFI/BIOS.
Every vendor is different so it is hard to say where the entries are.

I do not know LVM. But LVM is very particular and any damage to one area can corrupt the entire LVM. I do not think initially Boot-Repair can tell a mount of a /mapper is RAID or LVM so it thinks RAID then checks for RAID drivers. If no RAID drivers then it knows it is LVM.
