Notes for my system:
- I couldn't get legacy boot to work. Only UEFI (using an EFI System Partition aka EPS).
- The EPS can't be on the RAID0. You must allocate ~200 megabytes to the EPS.
- KUbuntu installer was so buggy that I couldn't use it. Use Ubuntu to set up the system and then install
kubuntu-desktoppackage. - When chrooting the EPS must be mounted on
/boot/efi. - I recommend using Ubuntu 16.04 inside of virtualbox to create a startup boot disk on USB of Ubuntu 16.04 ISO. At first a tried using an earlier version of KUbuntu and it took a lot of trial/error to discover I shouldn't have done that.
