With it only booting to recovery, you won't be able to make an installer out of that DMG. Just boot from recovery and start Disk Utility then select the drive name at the very top (like Seagate 1TB or whatever) and then erase the entire drive in Mac OS Extended format. By selecting the drive name rather than just the Macintosh HD partition you should get ride of all the partitions and be left with just the one.

Once that is done just click install OS and Lion will DL from the Internet and install. You will be asked for your AppleID you used to purchase Lion.

The issue with all this is while it will work fine, if the new owner ever needs to reinstall the OS they won't be able to since they won't have your AppleID.

If you still have the original OS DVD that came with the machine you would be better off reinstalling the original OS from there to avoid these licensing issues.
