Hi friends, I had WinXP and Ubuntu 10.04 installed on my system. I replaced WinXP with Win7 and lost GRUB (Legacy). Now my system started booting directly into Win7. So I tried installing GRUB (Legacy) again with Ubuntu live cd. But this time I end up removing NT loader as well and now I just get grub> prompt when I boot my system. I am able to boot Ubuntu manually from grub> prompt. So I did and created new menu.lst with all the commands and options I used to do manual boot
But still no luck, everytime I boot my system I get GRUB prompt.

It is presumed that your /boot is /dev/sda8 and has all the kernels, initrds your distro is installed in /dev/sda10 your /boot/grub has all grub files including menu.lst

Thanks a lot, now i get the grub menu after booting, but it doesn't show any entry for windows 7 ... how can i get that in list??
All you need to do is to add win entry in that same grub file at the end or wherever you like .(Assuming your win is installed in hd0,0)

<rant> Bloody hell! its that Ubuntu "upgrade-threadmill-like-proprietary" crap again... My system after an upgrade to 9.10 (or something like that boots at a speed which would make a tortoise/snail proud winner of the Olympics sprint and make me hate using the sullied "Ubuntu")... Sigh !!!
awaiting CentOS 6 in 4Q. Should be the best for the desktops atleast... don't have to worry for next 7 years!!! [i.e. 2017AD] :) . Now that's sustainable stability and innovation. looks they have chosen 2.6.34 kernel -- most advanced to date... any confirmations please...
YAY !!! </rant>

Cent OS is way behind. Use Debian Lenny instead. Get the latest version 5.04.

Forgot to add. CentOS 5 had kernel 2.6.18.

Ubuntu 10.04 has Grub 2 by default. So, instead of menu.lst, there's grub.cfg. You don't need to manually modify this file. Once you boot into Ubuntu, run 'sudo update-grub'. It should automatically detect your Windows 7 installation and add the corresponding entry in grub.cfg.
