simple steps to recover grub.

boot into the live cd and open a terminal windows. now type:

"sudo grub"

it'll then give you a grub prompt, "grub>"

now type: "find /boot/grub/stage1" at the grub prompt.

it'll give a output like this (hd0,7) 7 is here the example boot partition. note this down.

now type:"root (hd0,7)" (replace hd0,7 wid whatever output u'd got in the prev. step.

then type: "setup (hd0)"
it'll setup grub again.

now type:"quit"

its over! you get the grub menu now if at all the windows entry is not there. boot into linux after performing the above mentioned steps and add this line in /boot/grub/menu.lst:

title Microsoft Windows
root (hd0,0)
savedefault
makeactive
chainloader +1

hd0,0 above assumes that you've installed windows in the first partition of the first hard disk. if this is not the case then replace 0,0 wid relevant data to ur system.

This 1 did not help Well I did everything right but damn it

i dunno whats wrong.. its NOT possible that all the methods fail!!! i'd say get hold of a knoppix cd or similar which has a s rescue mode and then install grub the way mentioned before in this thread. it'll hafta work.

and from the fdisk -l output linux root sure is hd0,2. it shudn't give you any probs!!!! i fail to understand what is being done wrong and where!

ok wait.. ur partition structure looks a bit quirky to me!! sda2 is an extended partition. how come you haf one more extended partition on which linux is installed? (sda3)??? i think there has been some mess up while installing!!! and thats why all the above methods are failing...
