|Your link in response 1 works when I tried it just now - did you correct it yourself or did a forum moderator - e.g. OtheHill - do that for you?|
What other operating system(s) do you intend to multi boot this computer with ? If that's XP or 2000, there are things you need to be made aware of.
You are allowed to create or have up to 4 Primary partitions, or up to 3 Primary partitions and one Extended partition.
Within that Extended partition you can make one or more Logical partitions - e.g. on a hard drive I have , there are 3 Primary partitions, an Extended partition, and 4 Logical partitions within that Extended partition, for a total of 7 partitions.
Your picture shows dark green lines - a border - thicker on the ends, thinner top and bottom, around the portion of the drive's space labelled Free space.That indicates you have already made that space an Extended partition - you need to make one or more Logical partitions within that Extended partition.

(You can't make more Primary or Extended partitions because the entire drive space is occupied by the 3 Primary partitions and the Extended partition. )
If you want to be able to restore the original data contents of C, don't mess with your Recovery partition at all - leave it as is
Your System partition for whatever reason has no drive letter - it won't show up in Computer (in Vista or Windows 7) or My Computer (in XP and below) or Windows Explorer when it has no drive letter - one can be assigned to it in Disk Management if you wish.
You have lots of free space on some of your partitions.
You can make some of those smaller to free up un-allocated space if you like.
The unallocated space can be added to adjacent un-allocated space or to adjacent allocated space You can't re-size a partition in XP and below itself without losing all the data on the partition, but you CAN re-size partitions without losing the data on them if you use a third party program to do that. However, it's recommended that you back up the data on the partition one way or another BEFORE you re-size it.
I recommend using newer programs such as the freeware Easeus Partition Master Home Edition, rather than older programs such as GParted. It's 100% Vista / Windows 7 compatible - older "partition manipulation" programs are NOT.
You CAN re-size partitions in Vista and Windows 7 without losing the data on them in Windows itself, however the Help info in Windows itself about that is sparse. There are tutorials about that on the web.
