So you can't even get into BIOS? I believe you may need to press the Fn+F2 key (i.e. hold Fn and spam F2) on boot up. Then that should get you in the BIOS. Usually when Windows gets stuck at "entering setup" the SATA controller is set at IDE when it should be AHCI. Maybe your CMOS got reset somehow, and you will need to go into BIOS and change that.
