BIOS and Boot Menu load but screen is black with GPU installed

As the title suggests, I can boot normally under all circumstances, through the GPU, through the APU, no problems except that when I try to access the BIOS or Boot Menu with the GPU installed, which I need to be able to do, however the screen remains blank.
I know that it has loaded because I can still "navigate" it and exit the BIOS or the Boot Menu from memory.

I have attempted this process with several different displays of varying resolution and quality with the same result.

This is becoming quite frustrating as I need to be able to access the BIOS to do what it is I am wanting to do. Specifically set up dual monitors.

in the bios you have to set the pci/peg as first or primany output if you want the bios to show up on the gpu if not the bios screen on the ipgpu at boot.

I should also add that the BIOS on this machine is painfully lacking in its actual options.
The options pertaining to PCI only seem to apply to the Ram and Something else but not to the display, the display options that I can see without the GPU installed are minimal and performance related.

I will however attempt to do as you have advised, it is always possible that I have overlooked something. Taking notes now.

Alright, I think I know what you were trying to say, however without the GPU installed those options do not exist and cannot be changed. It blanks out the options pertaining to enabling/disabling/setting/et'cetera of the APU, I'm assuming because it requires some form of display capacity and without an alternative, the GPU, those options become unchangeable.

Also, note that this is not an IGP situation, it is an AMD APU, which seems to have complicated things more than actually helped them along and while it is stated explicitly that my GPU is crossfire compatible with the APU, I still cannot see the BIOS with the GPU installed.

could be two issues. one is a weak power supply and the gpu not turning on. the other is what device is the main primary device for video. on most mb you can set it in the bios if the bios code is working right.

The power supply one seems plausible but at the same time the GPU will turn on once I'm actually at the login screen. I will gave to test this... However I gave my superior power supply to a friend so that complicates things.

The BIOS options to set this GPU as the main display or otherwise I would have to first be able to see the BIOS while the GPU is connected, which I cannot do.

Thank you for your help, I will scrounge for a slightly more powerful harddrive or address borrowing my other for the express purpose of achieving this end.

The MB cap without the GPU installed is 512.
