This guide will discuss why the warning message appears and how we can fix it. Let’s start!
Why is VT-X disabled in the BIOS for all CPU modes on Windows 10?
Reasons for this warning message coming up can be many. Some of the popular ones are:
Virtualization disabled – For a virtual machine to work, Virtualization Technology must be enabled from BIOS. If it is disabled, the virtual machine won’t launch. Your PC is not compatible with VT-X / AMD-V – If your computer is old, it might not be able to support virtualization, and you won’t find VT-X / AMD-V. Physical address extension – If PAE & NX are disabled, it could cause the issue. However, configuring the virtual machine to run with Physical Address Extension & NX can resolve it. Third-party apps conflict – There could be chances that your antivirus conflicts with your virtual machine. To resolve this, you need to add the virtual machine as an exception or turn off real-time protection for a while. Allocated RAM size is too low – If you have not allotted enough RAM, this could cause a problem.
