rohitpatil, it appears where Leopard is located is brining you back into the bootloader. This happened to me once. The best way to fix this is to do the following:

fdisk -e /dev/rdisk0
flag 1
write
yes
quit
reboot

Instead of using the Windows Bootloader, you will use the Darwin bootloader instead. When you press enter in those 10 seconds you will have options to choose between MacintoshHD and Windows NTFS (Foreign, Windows Vista). =)
