I made the evident mistake of moving my User folder from C to D drive to free space; the next day most desktop and taskbar icons were blank, and at this point the machine will boot only to the Powerspec logo screen. It cycles in and out, and I can only shut it off and on with the physical buttons as it doesn't get to Windows. Holding down an F_ key or Delete, etc., while it starts has made no difference. Does anyone know how to get it to where I can change the boot sequence? It seems possible it could boot from D now instead of C, which must be the default.
