Description Leslie Satenstein 2012-11-27 01:16:46 EST
Description of problem:

Version-Release number of selected component (if applicable):

How reproducible:
Install Fedora 18 RC 1 from DVD.  On reboot, the grub menu does not show all other distributions.

Steps to Reproduce:
Actual results:
Fedora 17 missing from the grub.cfg.

Expected results:
Expected F17 to be includedé

Additional info:
Logged into root and reran the grub2-mkconfig > /tmp/grub.cfg.
Verified that the /tmp/grub.cfg included the missing distributions. 
Replaced /boot/grub.cfg  and rebooted.

Note. For full inclusion with multi=boot, all alternate partitions should be mounted.

Please show the output from os-prober.

If possible then please also try it from the install dvd.

The problem is most likely caused by lvm/dm not being initialized correctly when running from the install dvd.

Please specify where the undetected distributions are located (partition type/file system type). I can think of two reasons for not detecting other OSes during installation:
1. OSes on file systems not supported in Anaconda
2. OSes on LVM partitions due to bug #825236 (in this case your bug will be duplicate of that bug).

The grub.cfg after Fedora 18 RC1 was installed.

This grub.cfg was created after I mounted the unmounted partitions. 
I used grub2-mkconfig

The file system is btfrs, the system is dual core 32bit (I can redo to 64bit if you need a 64bit version. 

The Intel dual core system has 3.5gig of ddr2. 

Anything else such as 

> *os-prober
> /dev/sdb6:Ubuntu 12.04.1 LTS (12.04):Ubuntu:linux
> /dev/mapper/vg_lesliedesktop-lv_root:Fedora release 17 (Beefy
> Miracle):Fedora:linux
> *

Can be provided.
Comment 5 Mads Kiilerich 2012-11-29 06:14:13 EST
Yeah, I'm quite sure that is bug #825236.

To confirm that please boot up on the install media and run 'os-prober' manually, perhaps on a ctrl+alt+Fsomething terminal.
