Restore the server from an ISO image
If system errors occur while working with the cloud server, you can restore the server from the ISO image.
You can recover a server from an ISO image if it is running any OS from its own image, or Windows OS from a ready-made image. To recover servers with Linux-based operating systems created from ready-made images, we recommend using Rescue boot.
1. Prepare ISO image
Prepare your own ISO image of the operating system with the necessary drivers. You can also use ready-made ISO images in WinPE for Windows or Rescue for Linux.
2. Upload the ISO image to the image repository
Use the instructions Download and create an image. The image must be uploaded to the Selectel image repository, which is located in the same pool as the cloud server.
3. Create a cloud server from an ISO image
Use the instructions Create a cloud server. As the source, select the image you uploaded to the image repository.
