E4rat Seriously Cuts Down on Linux Boot Time With a Few Simple Commands

This cut my boot time by at least half in Pinguy (Ubuntu 10.10). If you're feeling bold, give it a try. If your GRUB menu does not display on bootup by default (usually the case if you're not dual booting), you'll need to hold down shift to access it. It might take you a few tries to get the timing down. For a less frustrating method of accessing your GRUB menu at bootup, read on after the jump...

If you want to eliminate the headache of trying to get the timing just right on the shift key at bootup, you can also install a GRUB customizer that provides a GUI for changing bootup preferences, including whether or not to show the GRUB menu at startup. To download and install, open up a terminal and type:

sudo add-apt-repository ppa:danielrichter2007/grub-customizer
sudo apt-get update
sudo apt-get install grub-customizer

Now follow the steps in this short tutorial video to enable your GRUB menu.



Now when you reboot, you'll have a list of your current and previous Linux kernel versions. Highlight the most recent kernel version (you can tell by the numbers) and then follow the instructions in the Lifehacker article link above. Once you've configured E4rat and you want your GRUB menu to disappear again, you can simply open up Grub Customizer and un-check the same box I checked in the video. Now everything will be back to the way it was - except for, of course, your infuriatingly slow bootup times.

Good luck!
