I have a HP Compaq nx6310 notebook wth 4gb memory & a new 250gb hdd. After installing Ubuntu 12.04, i got an "out of disk" error & was unable to boot. I rebooted in live, instaled & ran Boot Repair then rebooted. Grub menu loaded fine, followed by "out of disk.....press any key to continue". I pressed a key & Ubuntu booted, a bit slow but still booted. So here are my questions: 1- Since Ubuntu DOES boot, should I just leave it alone? 2- If I need to fix this, HOW do I do it? 3- What causes this error?
