I installed a SUSE 12.1 and Fedora OS but GRUB does not indicate Fedora OS at opening.
Any ideas? 
You can use updategrub to add Fedora’s kernel. Unfortunately - most of the time - Fedora’s root partition has to be mounted in order for os-prober to detect the kernel.
The howto is about 11.4 but updategrub is also available and works on 12.1 Just install it from the 12.1 repo instead of 11.4.
I tried out Fedora 16 64 bit the other day and found a few interesting things of note:
- Fedora 16 uses LVM by default which would make its partitions hard to identify from openSUSE.
- Fedora 16 uses Grub 2, not comparable with openSUSE 12.1, which uses Gub Legacy, without further work.
- Fedora 16 does use systemd by default, just as does openSUSE 12.1
Its no doubt you would not just install one after the other without understanding the differences between the two and making changes to one to be compatible with the other.
Thank You,

I don’t understand why? openSUSE runs LVM just fine, so why would
volumes created by Fedora cause a particular problem?

I don’t know about Fedora in particular but Ubuntu also uses grub2. If
you install it to the MBR, Ubuntu will automatically build a grub.cfg
that includes an entry for the openSUSE system. Even better is to
chainload the openSUSE grub from the grub2.

That’s true of installing any two operating systems together, of course,
but I don’t understand why this combination would be especially tricky.
LVM is kind of like an Extended Partition which contains other logical ones, but as far as I know, LVM is not loaded by default, so you are not going to see the Fedora partitions to be added contained within and it is not just a Extended Partition but with many other capabilities. I think you expect too much of the openSUSE installer to determine this info (of pre-existing Fedora Partitions) by default.

I think you are confused because it takes special action in order to
boot from a logical volume, but that’s not the case here and there’s
nothing special needed to recognize and use logical volumes once the
kernel is loaded. I use LVM all the time on all my machines.
I suggest you actually try it.
OpenSUSE’s installer wouldn’t find Fedora 16 kernel anyway, whether Fedora is installed in LVM or not. It would have been easier to install the two OSes the other way around, IMO.
So, I did attempt to install openSUSE 12.1 onto a full disk with a Fedora 16 default install. openSUSE did see and identify the partition types and names. But its default installation was to delete it all. I don’t think my intent was to suggest LVM was not seen by openSUSE, only that the combination of default choices made by Fedora combined with the default choices of openSUSE would not cooperate with each other in anyway. And, I can see why anyone not prepaid for the incompatibilities between the two would fail when they tried to pair these two OS’ together.
Thank You,
The default is correct. But you should not run a default installation when you want to install several OSes on the same machine. Furthermore, since openSUSE tends to behave like Windows towards the other Linux distros, it should be treated like Windows, meaning installed first. The easiest order to install OSes is Windows, openSUSE, any Linux distro (but never with default installation). Of course experts might install OSes in any order.
Of course, after you have installed your Linux Distro of choice, the easiest way to try out the rest is in a VM. If some how it wins you over, you can always come back in later and load it in as the primary as long as you know just what it was doing with partitions in the VM. If you don’t know what they do by default and if you don’t know what to do to convince them to work together, you just got to stop yourself from loading in the second Linux OS until you know a whole lot more about getting the two to work together.
Thank You,
