I used to know how to edit \/boot\/grub\/menu.lst to change the order of Operating Systems (e.g. Windows XP, Ubuntu Jaunty, Ubuntu Karmic, and Kubuntu Jaunty), set the default, and set the delay. But with alpha 5 of Ubuntu Karmic that has all changed with the introduction of GRUB2. Here’s what I did instead.<\/p>\n
Your goal is to change \/boot\/grub\/grub.cfg but you shouldn’t do that directly. You should change some config files and then run a special grub update command.<\/p>\n
Open one of the config files for other OSs (as root): I commented out redundant entries e.g. different kernel versions, and then saved it.<\/p>\n Then edit the main grub config file: I changed the relevant line to: Finally, run the grub update command to regenerate \/boot\/grub\/grub.cfg: You can check the result in \/boot\/grub\/grub.cfg to see everything went well.<\/p>\n Not a lot trickier than under plain GRUB and apparently GRUB2 has a lot of possible benefits depending on your circumstances (http:\/\/www.gnu.org\/software\/grub\/grub-2.en.html<\/a>).<\/p>\n BTW GRUB2 has attracted some controversy and there are some interesting points in the following article and its comments (http:\/\/aronzak.wordpress.com\/2008\/09\/30\/stay-away-from-grub2\/<\/a>).<\/p>\n","protected":false},"excerpt":{"rendered":" I used to know how to edit \/boot\/grub\/menu.lst to change the order of Operating Systems (e.g. Windows XP, Ubuntu Jaunty, Ubuntu Karmic, and Kubuntu Jaunty), set the default, and set the delay.
