What Do I Do If an Exception Occurs When I Start an ECS Created from an Image Using the UEFI Boot Mode?

Symptom

An ECS created from a private image using the UEFI boot mode cannot start.

Possible Causes

The image OS uses the UEFI boot mode, but the uefi attribute is not added to the image.

Solution

1. Delete the ECS that failed to start.
2. Call the API to update the image attributes and change the value of hw_firmware_type to uefi.

   API URI: PATCH /v2/cloudimages/{image_id}

   For details about how to call the API, see Updating Image Information.

3. Use the updated image to create an ECS.
