So i installed Ubuntu after windows was wiped out by destiny and everything was fine until I wasn't able to start Ubuntu: it would stuck in a black screen with a blinking cursor forever. I made a bootable usb and the trick is, I can boot from USB, then restart my laptop and then and only then, it is able to boot from hard disk and I can access my archives and everything, until I turn it off and then I have to boot again from USB... etc. I am using 11.10 in a Dell Inspiron 1501 with an ATI RS482 [Radeon Xpress 200M] video card

Note 2. I used boot repair to no progress but I have this now:
