i dont know if i should post this is the boot camp section, because it involves it, but it also involves my hard drive. so i was an idiot and made my first partition not the way i wanted it. I have a windows vista, mac os x partition set on a macbook with 150 gigs. So i read a guide that said its possible to repartition your hard drive using disk utility. this also helps me because i have lost my vista and mac os x disks, but was told that i could create an image of my vista hard drive that i partitioned, and after resizing my hard drive, i could restore it. so i went into terminal and set the commands so i was resizing my disk0s2 (mac hd) to 50G and my other drive that i want ( assuming it will be my vista os) to be 90G. so it takes about 5 mins to verify, no progress at all, and then the first time i did it, it said "chosen size is invalid...". According to other forums, there is a work around for this. considering 50G + 90G= 140G, there should be enough space. so instead of trying to repartition into seperate parts, you only resize disk0s2, then restart, and then create the other 90G. so i try that, and another error says "Resizing encountered error on disk disk0s2 Macintosh HD: Filesystem verify or repair failed (-9957)". so i go and see if i can repair my Mac HD and see if that was the problem. says its fine. supposedly, i need my mac os x disc in order to repartition disk0s2.

can anyone give any insight about this to me please? it would greatly be appreciated
 
I don't think you can resize your OS X partition while you're booted from it. So you'll need a boot CD. If you don't have your OS X CD, you could use some Linux tools instead. I think the Debian installer can resize partitions (though I can't recall ever trying it with Mac partitions).

You should definitely back up your data -- all of it -- before attempting this. When resizing partitions goes wrong, it's not fun.
 
Download and install Winclone http://www.macupdate.com/info.php/id/25932. This will allow you to make a disk image of your Windows partition. After that use the boot camp set up utility to delete the Windows partition. Restart and then recreate the Boot camp partition. Then use Winclone to restore your Windows image back to the boot camp partition.
