Featured title Mandriva boot loader on Fedora
On this problem is considered first installed Mandriva on that later followed install Fedora. Filr Edit grub.conf under the etc directory
] # Vim / etc / grub.conf
title Fedora Core (2.6.18-1.2798.fc6xen)
root (hd0, 2)
kernel / xen.gz-2.6.18-1.2798.fc6
module / vmlinuz-2.6.18-1.2798.fc6xen ro root = / dev/VolGroup00/LogVol00 rhgb quiet
module / initrd-2.6.18-1.2798.fc6xen.img
title Windows XP
rootnoverify (hd0, 0)
chainloader +1
# Add the following 3 lines
title Mandriva
kernel (hd0, 5) / boot / vmlinuz BOOT_IMAGE = linux root = / dev/hda6 resume = / dev/hda7
splash = silent vga = 788
initrd (hd0, 5) / boot / initrd.img

How to find the three lines above are:

• Finding where Mandriva system, by using fdisk-l, in this example Mandriva system on / dev/hda6.
• Mount / dev/hda6, for example: mount / dev/hda6 / mnt / win.
• Open the menu.lst file under the directory / boot / grub on Mandriva system, here for example:     vim / mnt / win / boot / grub / menu.lst. In this file there are three lines previously mentioned above.
