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

Symptom

An ECS created from a private image booting to UEFI cannot start.

Possible Causes

The image is configured for UEFI boot, but the uefi attribute was 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.
