i was trying to install a fresh copy of windows 7 into my windows xp laptop. while installing i deleted two drives C and D. then created the C: but cannot create the D: and it shows an error report saying "Failed to create a new partition on the selected unused space. [ERROR: 0x8004240f]"... after that i just had to install the windows into my C:.. how can i get the extended free space into a logical drive. please suggest..
