Error 0x000000A5

  Installing Windows 7 on a Lenovo G50-30 laptop. At the beginning of the installation, a blue screen crashes with the error ".... The BIOS in this system is not fully compliant ... STOP: 0x000000A5 ... " or in Russian ... ... The BIOS of this system is not fully compatible with the ACPI standard. .. Error 0x000000A5 ... "
Photo 1. Error 0x000000A5, 0x0000000000000011, 0x0000000000000008, 0xFFFFFFFFFFD1 5018, 0x0000000000040000

   This case was different in symptoms from Not starting the installation of Windows 7 on a laptop . Then, at the start, the media with Windows installation was not even detected. Immediately the flash drive was determined, the installation of Win 7 started, but after a couple of minutes, the above-mentioned blue screen appeared. 
  Google did not help. I had to invent myself. 
  In the sequence of actions below, three points. There is a strong suspicion that only a third is sufficient. When I did the first two, I tried to install Windows 7. And again I got an error with photo 1. And only after the third everything worked. But just in case, here are all three of you. 
  Immediately I issue a sequence of actions that led to success.
Photo 2. Section "Exit" BIOS
  1. Reset BIOS to default settings. To do this, in the " Exit " section, select " Load Default Settings ". See photo 2.
  2. Immediately, the " OS Optimized Defaults " parameter was set to " Win7 OS " instead of " Win8 64bit ". See photo 2.
  3. In the " Configuration " section, the " USB mode " parameter is set to " USB 2.0 " instead of " USB 3.0 ". See photo 3.
Photo 3. Section "Configuration" BIOS
  Added later
  Forgot to add that as soon as you set Windows, return the "USB mode" parameter to the value "USB 3.0". Otherwise, USB 3.0 drivers will not become. And your USB devices (flash drives, scanners, printers ...) will work at reduced speed
