Keyboard problem when installing W7

[Ajrocket]

Hello, I have a minor problem that my keyboard and mouse does not work when installing Windows 7 on a computer that needs UEFI boot. I have a custom installation and it works via UEFI and I have a keyboard and mouse in USB 2.0. Unfortunately, the motherboard does not have PS2 input. I tried to disable legacy mode USB in Bios / UEFI and still nothing. I am switching back to 7, because 10 of them have annoy me, when a lot of DLL files are missing and even after multiple reinstallations, it throws me 0xc000007b for every 3D application. I tried (NET FW, DX, dll files, ..) but without any positive result, but that's a minor problem. Thanks much for the help. Ajrocket 

 

Specs if needed:  Asus Crosshair VI, RTX 2070, R7 2700X, HyperX Predator 2x8 3200MHz @3600MHz

IIRC Windows 7 doesn't work properly with Ryzen. I had that issue myself, switched to Windows 10.
