Title: Do not create a new partition table if the drive is already partitioned

Basically I manually specified a partition, hoping that the installer won't touch the other partitions which had valuable data, just to discover later that the MBR was wiped :v:

This PR modifies the installation script so that if the partition is manually specified the drive isn't repartitioned, because we already have a partition ready to be used.
