ive searched everywhere for something on how to do this, and the best ive come up with is this. i want to dual boot my vista. its for my brother and sister. they play lots of 3d games and such, and half of them crash my vista. so i found a work around to this, but it requires a mackintosh or anything of the like. i thought that a dual boot would be best since i use the vista for a few things, and i dont want my siblings to ruin my things any further. so im downloading the thing from the above link (not included) and im at the part where i need to shrink my vista partition. it only gives my 32MB to shrink. and ive tried everything to get it to empty out. and it says i have 50 out of 80GB empty! so what do i do to shrink this drive. and i would like to have the mac partition to be as big as possible.
