Basically when I boot it up, I see 3 partitions. One is very small, and I can adjust it normally, (too small) And the other two are large, but they are greyed out as all unallocated space, and I cannot edit them at all. Im trying to setup Vista for dual-boot, but without repartitioning, I can't figure out a way to guarentee XP or other files wont be discarded, moved or overwritten. So if anyone has any insigt on another method, or why I cant edit them, do tell. Thanks.
