Hi all, I've installed Linux Mint 17.3 on one of my PCs. I have also used it for a couple times without any problems. However this time when I tried to start it up it stayed on a black screen with a blinking underscore cursor thing at the top left of the screen, and nothing happens for a long time. Tried restarting couple of times but still the same result. Anyone knows what I can do to solve this? Thanks
