Hello,

I had my grub2 timeout set at 10 the other day (it was working), then I did a clean install and now when I'm trying to set it again and its not working.

I go into root, edit the /etc/default/grub

GRUB_TIMEOUT=10

save and run: grub2-mkconfig -o /boot/grub2/grub.conf

The grub.conf file shows the timeout set at 10, but when I reboot its still counts down from 5. Why did this work before, and not now?

Thanks!

There is a typo in that command. It should end in cfg, not conf, like this:

sudo grub2-mkconfig -o /boot/grub2/grub.cfg


If this answers your question, please mark this as answered by clicking the gray check icon to the left - it will change to a green icon.

just login as root or use "su" command to have superuser access

then open this file by an editor like "vim" :

vim /boot/grub2/grub.cfg

then find this line :

set timeout=5

change 5 to your whatever you want, then save and exit.

Manually editing grub.cfg is a bad idea - a warning at the top of the file even tells you that. Changes will get lost the next time grub2-mkconfig is run, and/or the next time the kernel is updated.

it works butyou need to be careful while working with this file, because an incorrect change will cause the system not start at startup.
