So I installed the latest BIOS version earlier today. I could no longer access the BIOS with  F2 or F12 so I went to the BIOS through Windows. I then changed UEFI to Legacy mode as I have Linux running on my second drive and needed to access at least F12.

Now it will only boot to my 2nd drive. I can not enter BIOS and it is essential for me to be able to access the BIOS. Any solutions?

Thanks.
