Ubuntu – How to see what happens during the boot process


On my machine booting takes more than a minute which is annoying when I see that Windows 7 boots in 20 seconds.

Here is what I get when the machine is booting.

How can I see what happens when booting up?

Best Answer

When you get to Grub (hold left shift on boot), edit the top option by pressing e and search the boot command until you see the two words "quiet splash". Delete these from that line and press Control+X to boot.

This will show you what's happening behind the scenes (and what it's getting stuck on).

This is temporary. It will revert to the old behaviour on the next boot so it's fairly safe.

If you want to make it permanent, edit /etc/default/grub as root, delete "quiet splash" from the GRUB_CMDLINE_LINUX_DEFAULT variable, save and then run sudo update-grub.
