I just freshly installed Ubuntu 15.04 from an USB pendrive to my Toshiba Satellite U940.
Normally this works great, but this time it was a real struggle.
I had several issues regarding grub2, installation failed due to grub and so on. Now I finally managed to get it working but my EFI doesn't boot from the SDD. I also tried
boot-repair of course. Still no bootable device according to the EFI. I managed to get a few lines of output by my PC via a slowmotion video. It says:
Failed to open \EFI\BOOT\grubx64.efi - Not Found
Failed to load image \EFI\BOOT\grubx64.efi - Not Found
and a few lines I can't properly read.
Boot-repair pastebin url is: http://paste.ubuntu.com/12623394/
I'm booting in UEFI mode, all secure boot measures disabled. No dual-boot, all harddrives fully deleted before install.
However I'm installing Ubuntu and grub on
sdb is my SDD and
sda my HDD. Can this cause problems? Boot order is set to boot first from SDD.
