Rufus allows you to build your own ISO from legit sources and puts the bypasses in place.
Yes it does, just disable it and it should work your hardware is unsupported that's why it doesn't install, already 5 other people also told you already so stop playing dumb and just disable it.
Why would you do that ? You can just disable it in the registry, they whole point of windows iso is that you want the original one.
That's because previous versions supported all Intel CPU's up to consumer 13th generation. Server 2025 dropped that entire CPU line up. Just Xeons, Pentiums and Celerons.
You're wasting your time beating this dead horse.
ok then why did windows 11 work on all those systems, but this dedi refuses to install windows 11 and windows server 2022, 2025
Wanting and getting are two different aspect of life which might not coincide.
I want my server to run original windows but if it fails to do that, then i will remove components one after the other followed by building the ISO till that point of time when it does get install. Then retrace through what modifications you have done and decide whether the removed components/files are essential enough to run the tests again.
well, i made a ticket 3 days ago with ovh and no response yet
. not sure if i made it at the right place though since some people said to use the api or something. guess i’ll keep waiting 😖
Bios updates?
bios updates? is that possible with ovh servers??
Can you install the Windows Hyper-V Server 2019 from the ovh template?
Why are you still beating this dead horse?
I don’t see any problem in trying. It’s always a guaranteed “no” until you ask.
Also, why do you keep commenting on this thread with input that isn’t really useful? The last time it was bumped was 12 hours ago, and you weren’t mentioned, so it wouldn’t have shown up on your front page. You also don’t respond to any of my follow-ups on your messages. If you don’t have anything helpful to add that hasn’t already been said, just don’t comment please. Giving me false hope whenever I log on the site, and see my thread is bumped.
ovh does not provide windows templates
Did you make an ISO with rufus and set TPM and other requirements off and try uploading it for use?
Yes, but it sadly didn’t work with Windows 11. Windows Server 2019 is the only server edition I can install
I have a 7th gen intel pc here at home that I was able to install Win 11 24H2 on with all those requirements removed. I'm surprised it wouldn't work here.
Have you tried finding an older Windows 11 ISO maybe like a year+ and removing the TPM requirement with Rufus?
That's weird cause I have it for my box. Anyway I had a similar problem where I couldn't install any windows version so I thought I'd try using one of their windows hyper-v templates just to see if their own template would install which didn't but it did prompted the automated system to alert technicians that it failed to install which got them to do a hardware diagnose. It took about half a day to get it fixed although they didn't really tell me what they fixed since their automated message said : Installation will resume

Telling you that hardware is not supported is about the most helpful advice. It's unsupported and inevitably going to be a problem when it fails to boot or install updates.
Unless I missed something, you've asked questions I've already answered, like:
Basically, I'm not outright saying you're wrong, but now I will say you're mistaken. You don't actually have this CPU running Windows 11 anywhere right now that you can see for yourself whether it can or if you're mistaken.
That's quite helpful, thanks for sharing.
Well, I did have this exact same CPU model run Windows 11 maybe around a month ago. I mentioned i had the same spec box from ovh in a previous message, and windows 11 along with windows server 2022 and 2025 worked.
Odd, i dont see this option. That saying, it only goes up to Windows Server 2019, which I can already install. I want Windows server 2022 and up or Windows 11 which is what fails.
Well then collect the setup logs and look for why it's failing if you care to keep wasting time on this.
I'm not sure how, though, since you're using an ISO and not USB flash drive.
maybe you tried already - but install using the first release ISO?

or, install using the Eval version and upgrade to non-eval with dsim.
I’m in exactly the same situation here on OVH KS-A and KS-B dedicated servers.
I’ve spent the last day and a half trying every possible method I could find, still can’t get Windows 11 or Windows Server 2025 to install successfully.
If anyone has managed to install Windows Server 2025 on OVH KS-A or KS-B, please share how you did it, whether through a custom ISO, modified installer, or a BIOS setting I might have missed.
Would really appreciate any insights. 🙏

Use this to create a custom ISO that disables all hardware checks.

Best place to grab original MSFT ISOs
Lucrative market, I buy those for heating my home while solving puzzles.
Seriously, try flyOOBE, while Microsoft keeps closing loopholes, people find ways to bypass the bypassing. They install the server, for example, then revert to 11 if that is your flavour (but you should know that, AFAIK, client windows in datacentres/VMs are not OK by EULA).
Add SPL key windows evaluation 2025 to OVH license panel, and you can install easy by using windows temple in control panel
What iss spl key?
Please explain more details...
