You did say in your original post that to downgrade to Win 7 you need to update the BIOS so maybe it is required and will solve the other problems you're having. I have updated many BIOS and so far bricked none so it's not as if it's a total certainty it will happen and as long as you follow the instructions to the letter it should be fine. The cursor problem you're having does it do in in any program or only one or in Windows in general
