got a laptop and i'm wanting to resize the OS partition that Vista is installed on but in disk management i'm only being allowed to shrink it by 3GB when there is 30GB free of 64.5GB total space. why is this, and is there anyway around it? i don't want to use any software that is going to ruin the Vista installation, and i know that resizing using Partition Wizard will do exactly that. so does anyone know a way for me to do this and still be able to boot into Vista properly as is???
