I have a machine with UEFI BIOS. I want to install Ubuntu 18.04, desktop version with RAID 1 (and LVM) so my system will continue to work even if one of the drives fail. I haven't found a HOWTO of how to do that.
The desktop installer does not support RAID. The answer to [this question](https://askubuntu.com/questions/355727/how-to-install-ubuntu-server-with-uefi-and-raid1-lvm) almost works but requires some GRUB shell/rescue USB disk and UEFI settings magic. Is anyone aware of a procedure that works without the magic parts?
