I got a Lenovo G50 laptop which came with Windows 8 preinstalled on it. I have used this laptop from quite some time and now I am looking to install Windows 7 on it. But when ever I am trying to install it then it gives me an blue screen of death error message that states "The BIOS in this system is not fully ACPI compliant Stop 0x000000A5". Can anyone please tell me how do I solve this error so that I can use Windows 7 on this laptop? Thanks
