This is marked solved, though no comment indicates that it was solved.
The SATA compatibility is a nice tip, but I've been using 11.0.1.1533 and PC-DOS boot keys with SATA drives for a few years without this problem (Optiplex 280, 320, 520, 745; ThinkCentre 7359 )...
In our case, under the same Subject line, PC-DOS isn't booting at all. After "Starting PC-DOS", no further screen activity.
"WinPE can be..." leaves out a substantial part of the story. I'd be happy to accomplish that, and yet time wise the Ghost Boot Wizard is at hand.
