I'll see if a different subject, devoid of anything but the question, brings a response. When I installed FC18 on a drive with FC17 and XP the installer didn't offer an option to boot those OS as alternatives.
Is this a bug or by design.

I installed F18 in a Macbook Pro with Mac OS X in another partition and Mac OS X shows up in Grub.
I am not sure if it is the task of the installer to set up booting other operating systems. It is Grub that enables that. Grub2 looks for other operating systems when updating its config and it should add them to the menu "automagically".
To update Grub's config I run:
# grub2-mkconfig /boot/grub2/grub.cfg
(Note: I use Grub2 and BIOS, configuration for EFI is different)
Greetings,

Have done that, thanks for the reminder! However, that didn't result in XP or fc17 being detected. Is there some magic I can do to tell grub2 to actually use the fc17 boot and root, or am I screwed? The XP is less of an issue, I only use it to check that websites are viewable with IE, and I can just boot it under KVM and run it in a VM.
I avoid editing the grub.cfg file for three reasons: 1 - I don't know what I'm doing, if magic is needed the install/upgrade should be the magician. The average users knows way less than I do about system setup. 2 - The last time I did the system wound up being a totally unbootable recovery adventure. See #1 3 - every kernel upgrade seems to rebuild the config file, making change a brief success.
All suggestions appreciated.

3 is completly untrue
until now after kernel updates grubby is adding the new one to grub config and taking any chnage you made in the previous one to the new entry
only "grub2-mkconfig" is creating a complete new config with all this submenu crap and so on for kernel params "/etc/default/grub" is your friend here

Try it this way: grub2-mkconfig -o /boot/grub2/grub.cfg

The modification date on the file and it's contents change. Since I have never been able to get it to add either fc17 (separate boot and root) or XP in a partition, I couldn't investigate what it was changing, but it does get rebuilt, which is what I based my statement on, I actually looked. If having it change doesn't meet you criteria from being rebuilt I think that's splitting hairs.
If someone could tell me how to get it to boot any of the preinstalled OS on the drive, I could do better testing. Better yet I could upgrade and move on.

I am not a guru on grub2, when I did this with fc16 along with fc14, both appeared, I was asked (my notes don't say if it was a question or menu) if I wanted to boot fc14. That was good, the current "ignore the other stuff" doesn't seem like an optimal install interface, Fedora users tend to be technical, but having to hack grub2 is a hard learning curve. BTW: copying stanzas from the old grub2 didn't seem to work, system just didn't boot.
Thanks for the input.

Thanks I'll try that and see if it finds the other OS on the drive.

Thanks! I indeed missed the "-o".

It didn't find either other OS, and copying stanzas from the fc17 grub2 didn't work, either.
