That's a problem with Windows, dhanu. Install Ubuntu in a free partition or a hard drive for... Ubuntu installation will automatically detect Windows installation in the other hard drive...Then will be offered to chose either Ubuntu or Windows at startup. Make sure you partition table is msdos/MBR not GTP. –  Naveen May 9 '13 at 10:25
