[ad#square] InWindows Vista, you will not be needing any third party application such as Partition Magic to resize/ split you hard disk partitions without losing any data.
To achieve the best results I recommend backing-up important data (you never know), moving any large files to an extra partition or flash disk, and finally run a defragmentation.
Now that you are ready, right click “Computer” from the start menu and click “Manage”.
Now click “Disk management” .
As you can see in the picture, select the partition to resize right click it and click “Shrink”
Windows will now decide how much space you can possibly cut from the partition (this is why we moved big files and defragmented the disk). choose the size of the new partition.
You can do this for the system partition, it’s not completely risk free but it worked ok for me at least.
This is particularly useful if you want to install an alternative OS for your laptop (windows 7 maybe) .
how do you like to partition you disks? many small partitions or just one or two big one? I would go for option 2 what about you?
