I've tried to install Ubuntu on a laptop, and despite the fact that the OS works perfectly fine on a computer that I used the same USB with Ubuntu 14.04 LTS that works perfectly, however the laptop has the error message in the title. Checking all of the similar questions, I believe my situation to be unique because the output of blkid produces
/dev/loop0: UUID="10d2b97a-01fb-449e-b1d9-f20307d5856f" TYPE="ext2"
/dev/sda1: UUID="9a1b340b-05d9-49bc-9aff-4221cc24dd5d" TYPE="ext4"
/dev/sda2: UUID="c685c3c2-c148-454a-b105-2826ae125607" TYPE="ext4"
/dev/sda3: UUID="ce995684-4dab-40cb-81fb-7edb5ba3b194" TYPE="swap"
and /etc/fstab shows
overlay / overlay rw 0 0
tmpfs /tmp tmpfs nosuid,nodev 0 0
/dev/sda3 swap swap defaults 0 0
I have tried updating grub (which I believe I should mention advanced mode doesn't work), boot repair (including replacing and updating the grub options), and even tried uninstalling a number of times (want to put the ephasis on how the OS works on my desktop perfectly fine, so thought it might have installed incorrectly) and none of those fixes worked.
Wanted to also note that my research indicated that the loop0 was supposedly a dual boot thing, which doesn't sound right, because it's just Ubuntu on the laptop.
