Comment 106 for bug 570765

I have install lucid on my machine, which was having both redhat as well as xp. After installation xp was there in grub but
redhat is missing. How to solve it??
After running "sudo update-grub" i got the following msg

Generating grub.cfg ...
Found linux image: /boot/vmlinuz-2.6.32-21-generic
Found initrd image: /boot/initrd.img-2.6.32-21-generic
Found memtest86+ image: /memtest86+.bin
Found Microsoft Windows XP Professional on /dev/sda1
Found Windows NT/2000/XP on /dev/sda3
Found Red Hat Enterprise Linux Client release 5.3 (Tikanga) on /dev/sdb7

As you have seen that it is showing redhat in the msg, but i reboot the system redhat was missing in grub menu.

looking for solution
