Type the following commands (one at a time):
diskpart
select disk 0
clean
convert mbr
But usually you can just delete the OS partition, (usually with System Reserved (usually the first one)), leave the recovery partition intact, and select the now-deleted partition as new space for W7 install. See here for images:
