I just deleted an XP from my dual-boot system. What I did was delete the BCD entry from vista bootloader pro and then deleted the XP volume from the vista system management tool, and uninstalled the bootloader. I want to extend my C:. As it can be seen below, my free space is right next to the C: volume and there should not be any problems in extending C:. I read somewhere that the space needs to be "unallocated" in order for me to extend the volume. How do I do this? My "extend volume" option is still grayed out. Please help I'm running out of space on C: !!
