shrinking partition in windows vista (not letting me)

Post Reply New Topic

im trying to shrink my /:C partition in windows vista to 15360 mb (15 gb) (i have 80gb free out of 160) so i can make a separate partition for when i dual boot both vista and leopard but the most i can shrink is up to 48mb. and ive tried everything. turning off hibernate, system restore, page file, all the stuff i need to do so i can degfragment my laptop (using power defragmenter the only one i find that works (well) in safe mode) but that doesn’t help either. am i doing anything wrong?


i also didnt sleep at all last night trying to do this. and i want to get a little f*****g sleep (ITS PAST 3:30 PM!) so if anyone can help please message or comment on this

and also please don’t raid this saying that vista sucks (xp was better) but i still prefer it over the f****d up overly simplified s**t that is called windows 7 (plus vista has dx9 which xp dosnt )

but i need to do this cause i need to dual boot leopard (hackintosh) so i can run the iphone sdk as my mac mini just broke and im currently in the middle of developing my awesome app

Nothing from XP forward will allow you to tamper with the active partition of a hard drive. You have to find a way to boot into an OS loaded totally into RAM memory.

IIRC, for my netbook (which had one HDD but 3 partitions for recovery, Drive C and Drive D), I had to download Unbuntu which I think had a partition utility on it. I copied it to a CF card and had to boot to the flash card (you might be able to boot from CD on your PC).

Since the HDD wasn't using any active partitions, I was able to use the utility to delete the partition for Drive D and resize the Drive C partition to take up the remaining space. When I rebooted into XP, it had to run a HDD check because the data regarding volume size had changed, but everything else went fine.

Perhaps someone else can confirm that I detailed the steps properly.

Oh, if you're going to make a dual boot system, you MIGHT have to do a total wipe and install. XP and later OSes from MS do not play well with another OS installed AFTER the MS OS has been installed. I'm sure there is a way around this, but I found the easiest thing was to use an aftermarket boot manger (like BootIt Next Generation) and start from scratch. You'll need someone more savvy to walk you through. My current dual boot uses two separate physical HDDs, not a physical drive partitioned into multiple drives.

I was just looking over an old MCSE training CD, and it was talking about Disk Manager in MMC...maybe you could look into that. The trick is to make sure there's no data in the areas you're trying to format.


No matter what you do..BACK UP YOUR STUFF FIRST!...just a thought.
