[Solved] How to remove old grub2 entries

fonsopr · 2012-10-30 03:44:27

Hello,

My machine dual boots Statler and Archlinux. I installed #! first, so it is the distro that controls grub2. Ever since I installed Archlinux, I have duplicates of both of my #! grub2 entries (the regular one, and the recovery one). I've done some research on the matter, but still I have no idea how to solve the problem.

The tutorials I read directed me to /etc/grub.d. The files therein do not correspond to the entries in my grub 2 menu.

alfonso@crunchbang:/etc/grub.d$ ls -al

When I look into the 10_linux entry in grub.cfg file, it makes a little bit more sense, but I don't know how to alter grub.d to achieve the desired results in grub.cfg.

Here is the part of my grub.cfg relating to 10_linux:

### BEGIN /etc/grub.d/10_linux ###

Thanks in advance for any help,

Alfonso

It looks like you have two kernels from your #! install, probably from a dist-upgrade

vmlinuz-3.2.0-0.bpo.3-amd64

and

vmlinuz-3.2.0-0.bpo.1-amd64

they are not duplicates...

I use kernel-remover from the aptosid repos to remove them all that I am not using. smxi is also a good tool fro removing dead kernels.

Thank you for your quick response VastOne.

Is smxi available in the regular #! or debian repos? Or do I need third party repos for it as well (I'm usually hessitant to use them).

Can't I just remove the old kernel manually through apt-get and then do a grub-update?

See my sig line for the smxi site, it has very detailed instructions...

It may be easier to just add aptosid repos and get kernel-remover, I like it as a better choice.

All you have to do is add it just for that file and then remove it...

Add this to /etc/apt/sources.list

deb http://oscar.aptosid.com/debian/ sid main fix.main

sudo apt-get update

sudo apt-get install kernel-remover

Then edit /etc/apt/sources.list again and take out that repo

and another

sudo apt-get update

And you are done...

Yes, you can do that too!
