I have lost my grub I dont know how:confused:..so i popped up my ubuntu live cd and entered commands:
sudo grub
root (hd0,7)

i followed the same method when i lost my grub earlier...but somehow i dont know but its not working now
waht should i do?????

also I am able to mount my linux partition on temp folder....so the partition exists 4 sure
