Once that's done, it wouldn't hurt to download your motherboard and video cards drivers onto a flash drive or something for Win 7 x64.
From there, pop in the CD, boot from it, click Install. If you only have one drive (it doesn't hurt to unplug your external if you have one, just to be safe), delete the partitions on your main OS drive, and just click 'install' and it will handle the formatting, partitioning, and the reserve partition.
