How to create a custom .raw image for OVH “Bring Your Own Image” system

Hello,

I have a server and I wanted to use the « Bring Your Own Image » system to install a Windows Server 2025 version with everything I need. I’ve tried looking for tutorials or guides on how to create my own image, but I haven’t found anything. I already have another server on OVH running Windows, and I wanted to be able to export all my content without compatibility issues.

However, there is no guide anywhere on how to create a .raw image. In OVH’s documentation, the only information about the system is a very basic explanation of how to “import” an image, but that doesn’t help if I don’t have anything to import.

If someone could guide me a little, I would be immensely grateful!
