Hello everyone, I recently bought a Lenovo G50 but whenever I try to install Windows 7 I get the "the bios in this system is not fully acpi compliant" blue screen error.

Things I have tried:
-Setting the ACPI to 4.0
-Trying different Windows (32bit, 64bit, Home Premium, Ultimate)
-Trying to install via pendrive, DVD

I have no idea, the BIOS is InsydeH20 rev. 5.0

Your GOAL is to review the bluescreen solvers and then try it, or update BIOS, Make sure that ACPI is 100%, If not, The BIOS are outdated, See if that helps.

This means that the PC on which you are installing Windows 7 is set up to be a Windows 8.1 machine in the BIOS. There will be a setting somewhere that allows you to change it to Windows 7 compatibility.
