Red Hat Bugzilla – Bug 880491
Grub2 fails to add all alternative distributions
Last modified: 2012-12-03 03:05:47 EST
Description of problem:
Version-Release number of selected component (if applicable):
Install Fedora 18 RC 1 from DVD. On reboot, the grub menu does not show all other distributions.
Steps to Reproduce:
Fedora 17 missing from the grub.cfg.
Expected F17 to be includedé
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).
Created attachment 653982 [details]
The original grub.cfg created by Fedora 18 Rc1 with btfrs as default file system
Created attachment 653983 [details]
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
> /dev/sdb6:Ubuntu 12.04.1 LTS (12.04):Ubuntu:linux
> /dev/mapper/vg_lesliedesktop-lv_root:Fedora release 17 (Beefy
Can be provided.
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.
