Adding unallocated space to primary partition during Windows 7 install

I'm doing a fresh clean install of Windows 7. In the select partition screen, I saw there were two:

-100 MB of type "System information", or something like that.
-700 GB of type "Primary", my current partition and the one I want to install Windows 7 in.

Anyway, since I didn't know what the first partition (100 MB) was, I decided to delete it (which probably was a mistake), expecting it to automatically merge all that space with the primary partition. However, this didn't happen, and now I have a 100 MB partition called "Unallocated Space". I don't want to have 100 MB unusable and I know there must be a way of merging this space with my primary partition using DISK PART (which I can access from the Windows 7 installation wizard by pressing shift + F10), but I have no idea of which commands to use to accomplish what I'm trying to do. Any help? Thanks!

How do I do this, Novuake? Also, I need to leave at least one partition available right? You need to select one to install, otherwise it won't do it, I think.
 


Just delete every partition on the main drive(note this will get rid of your data) and then select the HDD and install, as simple as that.

How do I do this from diskpart? I don't really know which commands to use, and I'm pretty scared of messing something even more because I don't really understand very well concepts such as drives/partitions, etc.
