Re: [opensuse] Grub2 and installing multiple distros on same computer

A while back I had a bit of a gripe about grub2 (vs grub) because it wasn't clear how I would be able to install other distros on my computer apart from my main openSUSE. At that time I wished that I had used grub when I installed 12.2.

Well, earlier today I took the plunge and decided to create the situation whereby I could install Tumbleweed and openSUSE RC2 later today - or, if I failed, to re-install 12.2 from scratch using grub.

With my heart in my mouth I started the procedure - only to find that I still had a working 12.2 but now with the ability to install more distros.

In fact the whole process was "a piece of cake" so to speak.

If others are contemplating doing same I recommend reading which is where I got my "inspiration" from:

use Okular to view it, and save it.

The article is titled, "Installing Multiple Distributions on the same computer".

Read this article SEVERAL+ times before doing anything.

I read the article before I installed 12.2 and chose to go the Case #3 way when installing 12.2. 12.2 was installed, but then I got stuck with working out what to do next - and only found the stomach to "take the plunge" today.

However, just before the end of the process I broke out in a profuse sweat because on page #16 of the article it states, "Then run the command sudo grub-mkconfig -o ..........". When doing so I got the error message that I was way up there with the fairies as the command "grub-mkconfig" is something I dreamt up after being sprinkled with Tinker Bell's pixie dust.

Well, the answer was that the command should read "grub2-mkconfig". Once I found this out everything worked to its finality as expected.

One more thing:

go into YaST2>Bootloader and make sure that it is sited as described in the article. If not, adjust and save the changes.


I use legacy grub to boot multiple distros.
grub2 is too confusing to use.

No, no it isn't it. It is quite easy.

To add a new distro in legacy grub, all you have to do
is add a new stanza in /boot/grub/menu.lst as below:

With grub2 you don't need to do this (unless you really want to) because all you do is to execute 'grub2-mkconfig -o <path-to-grub.cfg>'

title SuSe 12.2 at sda6
root (hd0,5)
kernel /boot/grub2/i386-pc/core.img

The important thing is to locate where core.img is.
Some distros have core.img as : /boot/grub/core.img

Most distros install grub2 in the MBR, you have no choice.

Could you please name them?

I use mepis 11 which uses grub legacy and booted suse 12.2 as above.

But of course. When you have 2 OSs then there is no problem with anything - its just like dual-booting with Windows and, say, openSUSE with whichever bootloader it uses- lilo, grub, or grub2.
