I have tried using e4rat numerous times on two different computers following a couple of different guides, including the one on howtogeek. I have gotten up to the point every time where you add "single" to the end of the line starting with "linux" after pressing "e" in grub while Ubuntu is selected. I do this, and every time I get a black screen with a little cursor blinking in the upper left corner of the screen, and no matter how long I leave the computer alone (I once left it just sitting there for three hours straight) that is all that shows up. I do not get a login prompt. I am able to type things if I press alt+F1 and what I have typed is hidden when pressing alt+F2, and then shown again when I press alt+F1. I am following the guides exactly and I always get the same results. So if anyone can recommend an alternative to e4rat or a solution to this problem, that would be great!
I am running Ubuntu 12.10, if that helps.
Thanks for your help in advance!
