It's the "primary boot record 2" message from the factory.
The machine has three partitions from the factory:
1) Dell utility partition
2) OS partition (the one you're seeing here)
3) The hidden DSR / Dell system restore partition.
Looks like you are having a problem loading the O/S. Might need to try a recovery using the disks that came with the system (this will set it to how it was when u bought it), or better still, try to repair it. Maybe running 'fixMBR' (fixMasterBootRecord) from a boot disk or similar will do the repair.
