Tried to install three times.

This message from Windows Update.




Error code is 0x800701b1



Has anyone got any ideas?

@Neil_Imrie same issue here.

I tried both the beta and release preview channels for the 22H2 update. No luck in both cases.


Windows 11 is running on a dell XPS 17

That is interesting. I am running Windows 11 Pro on a Dell Inspiron 5770. I wonder if it may be an issue with certain Dell computers.
nope I have a Toshiba and I am also unable to install with the same exact error message


I have a Lenovo and there is the same error message.

Try it once. download it externally as iso file and install it.



I've tried that. It's not successful either. 

My Windows 11 thinks it update on 2023-03-12! and don't get any update. its in update history.



In my case it seems the issue is because I have dual boot system, and the EPS partition which was about 100 MB was not sufficient for both Windows, Linux and Firmware update, so I have increased to 1000 MB.
