ok....so....can I assume that you pressed the f11 key during boot up to restore to system factory settings. And then it went into a mostly text based installation routine?
If so, the answer is likely no. The f11 key was accessing a hidden partition with a specially created master boot record. When you reinstalled windows, you wiped out that master boot record (though the hidden partition may still be present).
To recreate that, you would need to re-image the drive. Dell may have a restoration cd that can do it, but re-creating that mbr without Dell's help---I just cannot see you being able to do that.
If you could find another dimension 4600, you could possible copy the MBR to your machine, but whether or not it will work is up in the air. If you wiped out the hidden paritition, it definitely will not. If you did not, it might work...
