Guide: Manage ISO Images

The ISO appears in the list with Uploading status and changes to Active when complete.
Note: The upload progress is displayed directly in the list. Do not refresh the page to avoid interrupting the upload.

Use an ISO Image When Creating an Instance
Once the ISO is in Active status, you can select it as the boot source when creating a new Instance (depending on the VPC configuration and the Instance type supporting ISO boot).
Important: Installing an OS from an ISO requires console access (VNC/Serial) to the Instance. Make sure you are familiar with the installation process for the corresponding operating system before proceeding.
