Guide I was using: OpenCore Install Guide (dortania.github.io)

Hi there, I was following this guide the best I could when I got to this part and I encountered a problem. I went into the BIOS to change the settings listed. Fast boot and secure boot were already disabled, so I could ignore those. I disabled serial port and I disabled CSM, however I could not find parallel port so I just ignored it. I could not find any of the things t enable except SATA mode, which I set to AHCI as it said. The guide says that if you cannot find above 4G decoding to add npci=0x2000 to boot-args, so I saved changes and left the BIOS to do that. I though, alright we are almost there! now I just need open BIOS to boot to the OpenCore USB. However, I was unable to open BIOS. When I pressed the BIOS key both my monitors would just say no signal. If I did not press the BIOS key I would boot to windows 10 just fine. I tried switching the display port cable to the motherboard but that did not work either. I tried going to settings>Update & Security>Recovery>Restart now>Troubleshoot>Advance options>UEFI Firmware settings, but that yielded the same results.

Thanks in advance
