@arnaudrigole I believe I understand what you’re saying. You already have Windows installed on the machines, and switching to AHCI from the current RAID configuration will make your install unable to boot.
That said, while I understand the hardship it can require, you could switch it to AHCI and reinstall the instance of Windows.
That said, it seems, too me, that you may be potentially doing something illegally.
- You have your machines and they came pre-installed with windows. This is fine by itself, but trying to capture an image is not technically allowed.
- You’ve customized the machine to how you need it, and are trying to make an image that you can use for multiple machines of the same make/model. This shouldn’t cause any major issues from a legal standpoint so long as the machines to be receiving this image are using the very same install disk and software. But I believe customizing the OS is not allowed from a legal standpoint.
If you’re hard set on using the RAID in the current mode, I believe you would need to add
mdraid=true on each of the machines
host arguments that this would impact.
