Welcome to Geeks To Go!
This error seems to be unique to Dell systems and usually means that the recovery image on the hidden partition is damaged/corrupted.
From what I've read, the only remedy is to fully install Windows from scratch from another source.
Since you don't have any recovery discs you will need to contact Dell who should be able to supply them for a small charge.
