Does AWS support Windows 11 EC2 Instances?


When we would like to spin up Windows 11 EC2 instances, we go the following error: ENA must be supported with uefi boot-mode

We tried out many things, but without success. Thanks,

It sounds like you may be trying to deploy an instance type that does not support UEFI. Can you check whether you are using a current generation instance type such as c5, m5, r5, etc? (full list here:

  • Sorry, I wasn't concrete, I missed an important information: We get this error message, when we would like to convert the uploaded image to AMI. Our process:

    • Build the Win11 image locally
    • Upload the image to S3 bucket
    • Convert the image to AMI

    The above solution works in case of Win10, but in case of Win11, we got the mentioned error message.


VM Import/Export added support for Windows 11 images (and Secure Boot). After importing the UEFI image, you do need to use a supported instance type

Check out the blog post Bringing your Windows 11 image to AWS with VM Import/Export for more info.
