Upon installing Ubuntu 14.04 alongside 12.04 and XP, no boot menu entries appeared until 12.04 upgraded to 3.2.0-65. Then the following 3 lines appeared. Ubuntu' --class ubuntu --class gnu-linux --class gnu --class os 'gnulinux-simple-UUID -> Ubuntu, with Linux 3.14.0-24-generic' --class gnu-linux --class gnu ----class os 'gnulinux-3.13.0-24-ge-> Ubuntu, with Linux 3.13.0-24-generic (recovery mode)' --class ubuntu --class gnu --class os 'gnuli->
Question 1 are these normal GRUB menu items? "UUID" replaces the real string. All lines were wider than my screen. They did all boot the same OS until I messed up the video.
Question 2 Can I wipe the partition and re-install 14.04 without confusing GRUB?
Question 3 Does grub-update need to be run in the 12.04 partition to add the menu items for 14.04?
Question 4 Irrelevant to the above but I wish to adjust my thinking to the proper view. http://en.wikipedia.org/wiki/GNU_GRUB refers to stages 1, 1.5, and 2 for GRUB 2. Is this terminology correct?
