How can I fix my hard drive partition?

Sam repartitioned his hard drive and now he's having problems with it. Leo says that partitioning is no longer necessary with today's modern hard drives. Sam has an issue that his partition isn't large enough now, though.

Leo advises repartitioning the drive to a single partition, then restoring Windows from the hidden recovery partition. Sam can do both from the install option. The key is to not delete the hidden partition. A third party option for this is EaseUS.
