Whether you have mining mode enabled or not it doesn't matter. Enabling it only enables above 4g decoding and disable csm support.

If you disable csm support and didn't install windows using uefi mode then you will have issues. You don't have to enable mining mode. Just enable 4g decoding and enable csm support.

My settings are Disabled Intel virtualization, Pcie gen 1, enable 4g decoding, initial display igfx, mining mode disable, enable csm support. Unless you know you have flashed your windows 10 in uefi mode then you can go ahead and disable csm support. Make sure under csm video is uefi then save and reset and go in bios and then disable csm support.
