Cannot install Windows 11 - Error 0xc1900101

Hi Frank,

Unfortunately, SP4 hardware doesn't support W11 and if you weren't in the DEV channel before 24/06/2021 you can't install Windows 11 preview on it as MS has put a block on it. Some people have found work arounds to bypass the block.

I have two SP4 that do run OK with W11 but the CPU isn't supported which to me seems nuts as they run OK.

Have you used any of the following to find out what might be causing your error?

SetupDiag - Windows Deployment | Microsoft Docs

Resolution procedures - Windows IT Pro - Windows Deployment | Microsoft Docs

Troubleshoot problems updating Windows (microsoft.com)

Hi,
Thanks for the info, I will go and read the Articles

Still strange that I got the update without any workarounds.

I got a message this morning that I have to reboot for pending updates.

Regards

Frank

Same error with build 10.0.22000.132.

The 0xc1900101 error is generic. There isn't a single answer to resolve it. You will need to run SetupDiag (see above) to determine what is causing it in your specific case.

When I run that, it doesn't say much:

Even though people in the Dev track have a lot of advanced skills, needing to jump through these kinds of ridiculous hoops is crazy.

I partitioned my SSD, which was suggested by another fellow windows insider. I installed Windows 11 in that blank partition, and now I am up and running.

I had to reinstall all of my applications (all from Microsoft by the way) and move 750gb of files and folders.

Would I do it again to get windows 11? Without cussing, I would say no!
