Today I installed Fedora 14 in a different partition in the same hard drive as Ubuntu. At the Fedora 14 installation, I chose not to install Boot-loader in the MBR, and instead chose to install it in the Fedora partition itself, which is according to my HD layout /sda3.

After the Fedora 14 installation I booted in to Ubuntu and ran

sudo update-grub

but 'grub.cfg' fails to add Fedora 14 in to the OS list. Here is the output of boot-info script.

                  Boot Info Script 0.60    from 17 May 2011





============================= Boot Info Summary: ===============================



 => Grub2 (v1.99) is installed in the MBR of /dev/sda and looks at sector 1 of 

    the same hard drive for core.img. core.img is at this location and looks 

    for (,msdos1)/boot/grub on this drive.

unlzma: Decoder error

According to this Fedora 14 is visible in sda3. Does anybody know a way to add Fedora 14 to grub.cfg of Ubuntu so I can choose which OS to boot? Thanks in advance.
