Partitioning a Hard Drive in Vista

To create a new partition (Vista calls it a "volume"), click the Start button, type diskmgmt.msc, and press <Enter> to open the Disk Management utility. To create space for a new volume, right-click an existing volume and choose Shrink Volume. Vista will calculate the amount of space you can regain and will open a dialog box where you can enter the size of your new volume. (You'll also see the total size before the shrink, the maximum shrink available, and the size of the old volume after the shrink.) After shrinking, right-click the new "Unallocated" space represented in the program and choose New Simple Volume. Then follow the wizard's steps to create and format your new volume. When you're done, you'll see your new volume represented in Disk Management's graphs. Note that you can shrink only volumes that use the NTFS drive format. Your new PC's drive is almost certainly NTFS.

I tried to partition my 120GB Vista hard drive using the following:

In Windows Vista it is now possible to resize partitions without any data
loss in the new Disk Management console.

Resizing Partitions with Windows Vista:

Click on the Start Button and right click on Computer and select Manage.
Expand the Storage section and select Disk Management.
Then just right click on any partition and select either Expand or Shrink to
change the size of the partition.
This will allow you to safely resize your partitions without any data loss."

I had a 99GB C partition and a 10GB D Recovery partition as well as a 2GB
Blank partition. I tried to partition the 99GB C partition. Using the above
instructions I was left with a 63.1GB C partition, 10Gb D Recovery
partition, a 2 Gb blank partition and a 37GB unallocated partition.

When I tried to allocate the 37GB using the New Simple Volume Wizard an
error window popped up saying
"There is not enough space on the disk to complete this operation" so now I
have 37GB of space unallocated.

I can boot the PC and use the programs with no problems. Would like to
allocate the 37GB as another partition.

Any help appreciated. Thanks.
