Description Michael Adeyeye 2010-10-07 05:59:11 EDT
Description of problem:
I wanted to dual-boot; so, i tried to install Fedora 13 on my PC. I chose the shrink option during the installation, having had Ubuntu 10.10 use the entire disk. Anaconda shrank the drive but could not detect the existing Ubuntu OS. 

Version-Release number of selected component (if applicable):
Fedora 13

How reproducible:
Try an install Fedora 13 on a PC already running Ubuntu and has no free partition. Choose the shrink option during the installation

Steps to Reproduce:
1. Get a PC running Ubuntu and has no free partition/space
2. Choose the shrink option when installing Fedora
3. Restart the machine after installation
Actual results:
You would not be able to load Ubuntu again. The bootloader do not give option to choose either Fedora or Ubuntu. The PC would only load Fedora 13.

Expected results:
The bootloader (grub/2) should list the two OSs to choose one from.

Some more details:


/dev/sda1 - Ubuntu install (partition set to bootable)
/dev/sda2 - Fedora /boot (500MB)
/dev/sda3 - Fedora PV containing LVs for /home and /

grub was somehow created without a grub.conf file, which I recreated with grub and some magic.

It correctly discovered the fedora install but did not inform of the bpoot flag on sda1 and seemingly completely ignored it.

Could you attach:
  * install logs from /var/log/anaconda*
  * /etc/grub.conf

What version of Ubuntu?
