When I went to boot grub failed and went into grub rescue. I couldn't find a boot source from grub rescue and after running boot repair off a live cd when I power on I no longer get to the grub rescue command. I went back into to the live cd and ran the diagnostic in boot repair and got this http://paste.ubuntu.com/7137064/
I also used,
sudo fdisk -l
as mentioned on another thread and got an error:
fdisk: unable to read /dev/sda: Input/output error
This issue started randomly and I haven't made any changes to the partitions (intentionally) nor have updated recentlyso I'm starting to think it may be a hardware issue?
