Installing Ubuntu 15 on a Raid 0 - A little help

[Alexander_Paunovsk]

Hello, I've installed Ubuntu on a Raid 0 disk, but it won't boot.

I followed this guide here http://askubuntu.com/questions/334012/a-guide-to-install-ubuntu-13-04-using-a-raid-0 but it doesn't seem to work.

Here is my BootInfo paste.

I do not know RAID, LMV, not encryption.
But you need to install grub so UEFI knows to use the FAT32 ESP - efi system partition inside your RAID.
Most installs with LVM keep ESP & /boot outside of LVM. I guess it is a bit easier.

He does not have a separate /boot which you do.
So you need to follow his directions on mounting efi & system & also add one for your /boot. The run the grub install command. If booted in UEFI mode, it should add a entry to UEFI for booting.

What brand/model system. Some do not like ubuntu in UEFI and you have to do a work around which is an additional complication.

You do know RAID 0 is for speed with no backup and risk that if one drive fails you lose all data on both drives.
Don't bother with RAID 0 unless you have a specific need for speed without data redundancy, since if one drive goes out, you lose the whole array.
