I'll start by saying, I am asking this question after having read most of the similar threads out there and tried what they suggest but with no luck.
So, I have this laptop https://www.asus.com/Notebooks/X54H/.
I had Windows 7 installed but I erased them and I only have Ubuntu now.
When I restart my laptop and right after the Asus starting screen I get a black screen with a flashing underscore.
Editing grub file - Does not work.
Shift key pressed or spammed - Does not work.
Whole keyboard spammed - Works some times.
So what are your opinions? Any suggestions? Cause it's annoying to spam the whole keyboard every time, plus it's not a guaranteed solution.
Edit: Common fixes that worked for others like reinstall grub, run boot-repair, keys pressed during startup do not work in my case. I'm not an expert but I think it either is my graphics card (I don't know why but I've seen it being mentioned in other threads) or it's like the system is not booting from the right partition. Partitions are as follow:/boot(flaged for boot), / "root", swap and /home.
Edit: Here is the report from the last repair-boot just in case....http://paste.ubuntu.com/14279575/
