Restore a cloud server from an ISO image

If you encounter system errors while working with a cloud server, you can restore the server from an ISO image.

You can restore a server from an ISO image if it is running any OS from a custom image or Windows OS from a pre-built image. For servers with Linux-based OS created from pre-built images, we recommend using booting in Rescue mode.

1. Prepare an ISO image.

2. Upload the ISO image to the image storage.

3. Create a cloud server from the ISO image.

4. Repair the cloud server's volume.

5. Apply the repaired volume.

1. Prepare an ISO image⁠

Prepare your own operating system ISO image with the necessary drivers. You can also use pre-built WinPE ISO images for Windows or Rescue ISO images for Linux.

2. Upload the ISO image to the image storage⁠

Follow the Uploading and creating an image guide. The image must be uploaded to the Servercore image storage located in the same pool as the cloud server.

3. Create a cloud server from the ISO image

Follow the Creating a cloud server guide. As the source, select the image you uploaded to the image storage.
