Just a weird little item to consider if you’ve exhausted your other possibilities, but MS Natural Ergonomic Keyboards often do not send the F12 command to a vm you are trying to PXE. In the case of a vm that has not been imaged yet, you may get this same error message because it ends up skipping network boot and looking for an operating system which is not there yet. If you have an ergo keyboard, instead, connect a traditional rectangular usb keyboard and F12 should work fine.
