Windows XP with three drives were there. I've installed
Ubuntu 12.04 64 bit in of the three drives which I've mentioned above, installation went fine but after installation
Dual boot screen is not showing, windows is automatically loading.
I've tried answers which are found here and other
Ubuntu forums but non of them is worked for me. From forums what I came to know is,
Grub missing. To install or to repair it, I'm unable to login to Ubuntu, then how can
upgrade grub in
