Windows 10: Disable CSM

Hi, I am trying to disable CSM on my B450m Pro4 but if i turn it off my screen will go black until i clear the CMOS ( for my hackintosh). I had windows installed with bios UEFI mode (not legacy) and ssd formatted as GPT. Tried some random fix i found online and windows became unusable and had to wipe the ssd. With the ssd wiped I still encounter the same problem after disabling CSM.

My gpu is a RX 580 8Gb nitro, R7 1700x, bios version 3.50

Stuck on Aptio setup and launch CSM is disabled

Hi,



Thank you for writing to Microsoft Community Forums.



We understand your concern and in order to get clarity and to assist you accordingly, please reply with the answers to the questions below.

• When you say, “I am stuck on Aptio setup utility” are you able to boot the computer to Desktop?
  
• What is the make and model of the laptop?
• What is the Windows 10 version and Build installed? (Type winver in Windows search/Run command)

In the meantime, I suggest you to refer the troubleshooting steps mentioned below and see if that helps in resolving the issue:

1. Boot your computer up and wait for it to boot into the Aptio Setup Utility.
   
2. Once in the Aptio Setup Utility, navigate to the
   Security
   
3. Expand the Secure Boot menu
   section and disable Secure Boot.
   
4. Navigate to the Save & Exit
   tab, save your changes, exit the Aptio Setup Utility,
   restart your computer and wait for it to boot into the utility once again.
   
5. Navigate to the Boot
   
   
6. Disable Secure Boot and Fast Boot
   
7. Enable CSM (Compatibility Support Module).
   
8. Navigate to the Save & Exit
   tab, save your changes, exit
