Hi
It is not clear if you mean the same PC or several PC's which seem to be the same model
for instance old Dell Optilplex Desktops have Intel graphics and either 1MB or 8MB of video ram (selected in BIOS)
The Generic video driver used by BartPE does not like these chipsets. So the Start/Go button may be off the bottom or left of visible screen
ALT + M ALT + M may bring up the menu

I was working with several old Optiplex desktops and after hitting ALT + M frantically, it finally showed up.
Thanks for your help.
