GRUB Menu

[kona0197]

I've searched and I can't figure out how to remove entrys from the GRUB list. After I update the system and start using a new kernel the old ones appear on the GRUB menu on boot. I want to remove those. Any ideas?

It's best to keep the old kernel in case the updated kernel fails.

Yeah but I have more than two kernels listed, I have four. I want to cut the list down.

Assuming you mean Grub2, edit /boot/grub2/grub.cfg and comment out all lines of the entries you don't want. They'll come back when grub.cfg is next generated (e.g. next time there's a kernel upgrade), but it takes barely 30s to do anyway, so it's hardly back-breaking labour

If these are kernels installed as packages by yum, you can control how many are kept by editing /etc/yum.conf and changing the value for "installonly_limit".

Is there a program I can install that handles setting up GRUB? I don't like editing these files. It's tricky.
