Hello people, im having a problem with windows not booting without cms enabled.

all my disks are GPT and the system bios is set to uefi.

im using 2 ssd and 1 hdd.

follow this step by step in order (read till end):

• Boot to windows normally
• Disconnect from internet
• Uninstall gpu driver using DDU (clean and do not restart).
• Uninstall all the processors (is a must, should be 12 on yours, also when it asks for restart, click on no and keep uninstalling all processors) on device manager like this:
  
  
  
  
  
• Uninstall AMD Chipset Software in control panel (if there is none, skip it.)
  
  
• restart the pc to bios, disable AMD fTPM and secure boot if it was turned on by default, save and exit, go to bios again, flash to this bios first and then flash to the latest bios after it, then after updating bios go to bios again, then load default or optimized settings, disable CSM, enable Above 4G Decoding and Resizable bar option if you want to (these 2 options wont be available unless CSM is disabled), then save and exit.
  
  
• boot up to windows and install the latest Chipset driver (should be ver 4.03.xx), then reboot. Try to take a look on power plan if amd ryzen balanced power plan is available, if it's not then its okay.
  
  
• Install the latest radeon driver or try Anermine Zone driver, and then connect to internet.
  
  *do this all offline until reboot after installing chipset driver, also you may reboot to bios after all of this to set the XMP (and previous settings you did). Download needed files (highlighted word) before doing step 1, do the step in orders.
• Run cmd as admin, then do chkdsk /x /f /r, after that do sfc /scannow.
  
  
• And check windows update if there is any and install them (except optional update) and reboot
• Make sure the psu connected to the gpu is 1 pcie cable per 1 slot (use main cable, not the branches/split) like this:
