Fedora17 RC3: Unable to boot due to Error 15 (File Not Found)

[taytong888]

Hello,

I have a multiboot system where legacy Grub is installed in MBR and the root partition of opensuse 12.1. This has been working well until now. I can boot into Windows, Ubuntu, Fedora 16 Gnome and Fedora 16 KDE:

Here's part of opensuse's /boot/grub/menu.lst:

title Fedora 16 KDE (/dev/sda10)
root (hd0,9)
kernel /boot/grub2/core.img

title Fedora 16 GNOME (/dev/sda12)
root (hd0,11)
kernel /boot/grub2/core.img

I just installed F17 RC3 into the root partition of the same existing /dev/sda10 of F16 KDE and during installation placed bootloader (Grub) in the boot/root partition of /dev/sda10.

When installation is completed, I rebooted into F17 but got Grub Error 15 (File Not Found). I don't understand why, because I did the same thing, i.e. placed bootloader (Grub) in the root partitions when I installed F16 KDE and F16 GNOME.

Any suggestions?

"/boot/grub2/core.img" in in new place "/boot/grub2/i386-pc/core.img".
This chage is not in "Release Notes for Fedora 17"

I use
#
title Fedora F17 brc3
root (hd0,13)
kernel /boot/grub2/i386-pc/core.img
boot

flokip,

Your method did not work for me. I re-installed F17Beta RC3 placing bootloader in MBR and only this method works. From Grub2 menu, I can boot into any OS.

Latest disappointment:

Later when I updated Ubuntu 12.04 beta, its Grub(2) was updated also but somehow this messed up Grub(2) of F17 and now I cannot see F17 any where!

Any suggestions?

Fedora F14 is on MBR in mine system.

This is placed in F14 /boot/grub/grub.conf
#
title Fedora F17 brc3
root (hd0,13)
kernel /boot/grub2/i386-pc/core.img
boot

F17 is innstalled on /dev/sda14 with costom layout selectin one partition and option /.
boot is changed on first secotr on /dev/sda14
