Factory Image Restore for Inspiron 5737

Hello all,

I need to reset my 1 week old Inspiron 17R (5737) back to initial factory state (i.e., restore to factory image),  I have to install a certain application under Win 8.0 and I already upgraded to Win 8.1.  The usual procedure, according to Dell documents, is to shutdown and repeatedly press upon restart (before Windows boots up) in order to get the advanced Boot screens.  From there it is just a matter of using the correct menus to force a reset to factory image.

 I have tried this repeatedly, and my system does not respond to repeated pressing of .

Anyone have a clue how to proceed?:emotion-9:

Thanks in advance.
