I didn't make any effort to install it except to boot the OS from a USB drive. None whatsoever. It simply loaded the Ubuntu loading screen for eternity and went no further. When I tapped enter, the screen went black and nothing came back. The second time I reset it (and all subsequent attempts) it provided the following error message:
Kernal Panic -- not syncing! Attempted to kill init! exitcode=0x00000600 drm_kms_helper: panic occurred, switching back to text console
I had been dual booting with Linux Mint and Vista (which I used strictly for gaming... until now that I have no choice!). After putting the bios back, despite not clicking a single button to install or override anything, Mint is now inoperable. I can't get past the login screen because of a "failed installation."
I see so many similar questions unanswered. I guess Ubuntu has no quick fix? That's a shame. I wasted all that time downloading 13.04 when I could have simply updated Mint. Now I have neither.
