Do you need to disable CSM Support for Windows 11?
If so do you disable it before installing Windows or after?

Disabling CSM Support
- Thread starter Vakas
- Start date
Having a quick google Windows 11 does not support CSM Support.
You may need tp disable CSM Support to enable secure boot which windows 11 requires or you can create a USB of Windows 11 using Rufus which can remove these requirements.
you would need to do this before installing Windows 11 as it will fail to install as your system will not meet the requirements

Before, if you disable CSM on a Windows install that has a MBR partition I think it can prevent you from booting up.

Mbr2gpt first, but first use whynotwin11 to see if you need to.
Thanks just as I thought guys thanks for the information
I've managed to get Windows 11 installed with no issues
The question I have is when CSM is disabled not all my drives shoe up in boot options in my BIOS

Do they show up in disk manager when you're within Windows?
Are you trying to dual boot?
Yes they all show in Windows but they are not in the list for boot devices in the BIOS
If they're MBR partition this is normal, but it should not be a problem unless you're trying to dual boot with those devices.
Yes they are MBR previously used with Windows 10 but the drive Windows 11 is installed on is a new drive and I disabled CSM before installing but it does not show in the boot options,
The boot option shows to boot from windows boot manager and 1 other drive

I've had issues installing Windows 11 on older 939/1366
Downloaded a suitable image file from cough
Used rufus
Boot off usb, it progresses through install fine.
But on first boot it BSOD
Am I doing something wrong
Downloading new 24 iso I'll try again, but this time install on spare empty SATA HDD so I don't touch the working W10 install so if it BSOD I just reconnect the W10 drive

Computer says nope. CPUs must have SSE4.2. A lot of windows 11 requirements are complete twaddle but this is not. It's essential.

I'm trying now. On the 610e it got to blue window logo but restarted.
on the xeon I'm installing now I'll see how it goes.
610e isn't 939 it's am3
Nope didn't work, on first boot halts on "loading DMI information"
Also trying to run setup from the USB stick in windows onto existing drive but comes back with tpm/secure boot error and also (boot off usb stick) but I can't see if it's going to "upgrade" from 10/11, it says "keep nothing" so I presume that's just going to wipe the drive.

Ok tried on another install image, running setup in windows so update.
Gets through install, boot starting services than bsod. On both PCs is the same.

What's the bsod say? is it up long enough to get anything from it?
Irrelevant. Still doesn't have SSE4.2. You can't pretend answers you don't like don't apply to you.
Where do you have confirmation that 24H2 works with a 610e? From what I can see, it lacks the required instructions and I'm not sure if RUFUS works with 24H2 yet?

I've tried several isos, including 23H32.
Probably doesn't help with TPM/Secure boot thing.
5670 supports 4.2 and still doesn't install

TPM/secure boot is the twaddle I was talking about in my original post. Windows 11 certainly does not require this.
I'm running it on a MBR drive and no TPM...
My haswell cpu is not officially supported but it does have the required CPU instructions and therefore it works.

I presume this is normal when CSM is disabled?
