How i can see, your Win 7 is on extended partition an first one is primary.
1. Make order within Win 7. You have too much data on that partition. Big problem is
if it is on desktop or in "My Documents".
2. For this purpose you need another hard drive to make restore image from win 7
and transfer all your data to second drive. Make CD restore.
3. Bootup computer with installation disk and delete all partitions on first drive and make new partion how do you want. After that reboot but now with restore CD and
make restore operation.
