Windows 10: Cannot enable secure boot and core isolation at same time

I am not able to enable secure boot and core isolation at the same time on my PC.

I can enable either one of them (have the other one disabled), and Windows will boot properly.

But when I enable both of them, Windows will not boot and gets stuck on the spinning dots screen post-POST.

Ideas?

core isolation disabled itself in bios on new computer

Hello Khynnea,



Thank you for writing to Microsoft Community Forums.



It can be the BIOS update released by your manufacturer through windows updates which might have changed the status from Enabled to disabled. However here are the steps to enable it again.

• Open start menu and search for Windows Defender Security Center.
  
• Go to Device Security.
  
• You will be able to find Core Isolation, please click on Core Isolation details.
  
• Then you can turn it on.
  

Restart is restart is required for the changes to be effective. Please write back, if you need any further assistance.

Hope it helps.

How do you enable the core isolation?

How do you enable the core isolation?

If I have Core isolation enabled, but Memory integrity toggled off, what does Core isolation actually do? I am asking because the security center still tells me that Core isolation is active even after I toggle Memory integrity off.
