Hi guys,

I installed lubuntu through a USB drive, switching from windows 8 on a Toshiba Tecra R940, but now it won't boot (had the same problem with ubuntu). After some research I stumbled into this old thread: http://ubuntuforums.org/showthread.php?t=1633758
So, I entered the "try only" mode and obtained the following results using the bootinfo script:

I saw I don't have grub installed so I tried following the commands given to install it but this is what I got:

Code:

Installing for i386-pc platform.
grub-install: warning: this GPT partition label contains no BIOS Boot Partition; embedding won't be possible.
grub-install: warning: Embedding is not possible.  GRUB can only be installed in this setup by using blocklists.  However, blocklists are UNRELIABLE and their use is discouraged..
grub-install: error: will not proceed with blocklists.

Can someone please help?

The bootinfoscript you posted showed no code in the MBR, an EFI partition (sda1) with the correct EFI files and grub files on sda2 all as they should have been.
You don't need a BIOS Boot partition if you are using EFI which your output shows you are so trying to install Grub to the MBR was a mistake.
What was the original problem? I've read a number of posts referring to Toshiba as especially problematic for a non-windows system but don't have a Toshiba myself. Someone else should come along.

The problem was that I was supposedly able to install lubuntu or ubuntu but when I rebooted it would never go past the loading screen. Either way, I installed it in legacy mode and it's all good now.
