When installing Windows 7, the laptop reboots and displays a blue screen for a very short time. When booting into Safe Mode, it freezes on disk.sys. Error 0x0000005a. The BIOS in this system is not fully ACPI compliant.
In this video, I'll show you how I solved the problem installing Windows 7 on a new SSD by changing BIOS settings. My laptop is a Lenovo g50-30.
