9020, no post, no BIOS, black screen

So I just reinstalled Windows 10 and was attempting to get into a linux build via USB stick and must have got turned around in my BIOS settings because as the title states, those things are happening. In the BIOS I turned on legacy boot and I think I moved windows boot manager down in a list for some reason. I have tried clearing the CMOS by pulling battery(tried overnight too) and moving jumpers, but my BIOS will not return to default and I still cannot access it. The pc does go to windows but how i do not know. The screen is black but I can see the hard drive light going then windows appears.Can anyone help me figure this out?
