Hello everybody !
I kinda have a problem as the title states.My neighbour has a Lenovo G50 she bought and came with windows 8.1 x64 ( which she doesn't like at all and in my opinion win7 is far more superior ). The thing is I wanted to install her the Windows 7 Ultimate but everytime the " loading files " ends right after it boots from the dvd I get a bsod with the message " The BIOS in this system is not fully ACPI compliant Stop 0x000000A5 "
I tried all kind of different settings through the bios, changed from UEFI boot to Legacy / disabled secure boot / fast boot / I set the ACHI to compatible / but the end result is almost the same ( two times with different settings my screen froze with a red line over the top after loading the files )
My question is what is the problem and is there a fix for it? (of course it is,but I don't know it )

The solution is this....
getting the ACPI Error like this...
Step 1: Shut down your Laptop.
Step 2: Find the small NOVO button on Left side of your Laptop near the Power cord Point. Press the button. The System loads Boot Options..
Step 3: Click on the BIOs Setup Option. A Blue screen menu appears use arrow keys to navigate to Exit option and select
OS optimized Defaults to Win 7 ( The Default is Windows 8 64 Bit)
Step 4: If you are about to Install a Fresh Copy of Windows 7 Then Goto Configuration Tab and Change
USB Mode to USB 2.0 (Original may be USB 3.0)
In case you are already Running Windows 7 and the Problem was caused by Updating Your BIOS then
Then rest the Bios by using the option given in the Status Bar.
Step 5: Goto Exit and Select Exit Saving Changes. Select Yes
The problem should be gone.. and if It doesnt... Be Patient. Open BIOS Settings again and tweak around... Boot Mode or Boot Priority etc.

I managed to install the windows 7 64bit on a lenovo g50 30 by doing this:
I didnt flash the bios, didnt udate it. I restored the previous version of bios, in the bios settings. After doing this, there will be new options avalable to chose what os you want to install.
