[12:25] Trying to install Ubuntu Server 18.04 LTS on my computer. Seems like the computer mainboard is UEFI. [12:28] Downloaded ubuntu-18.04-server-amd64 made a Bootable UEFI USBkey. Booting up. run the wizard as normal. adding raid devices, made some lvm . Waited, Made /boot/efi/ fat32 partition The installer says everything is fine. booting up after installation. [12:28] The lines of text that shows up when trying to boot is: [12:28] GNU GRUB Version 2.02 [12:28] Minimal BASH-like line editing is supported. [12:28] For the first word, TAB lists possible command completions. [12:28] Anywhere else TAB lists possible device or File completions [12:30] Guessing i have tried 30 times, And still the same UnNice message shows up. But if i run the ubuntu-18.04-live-server-amd64 the raid selection, and lvm selection is not an option. but the system boots up if i put everything on / . But thats not a wanted option. Since i like to specify my installation the way i thought it should be.
