Dear Viktor Rolduhin
Thank you for posting in the Microsoft community.
You can refer to the following scenario to update Windows 11 to the latest version using iso.
So to give you the steps to repair and install WINDOWS, first of all, it is recommended that you backup your important data on your C drive to an external device
Select Download tool now - perform Media creation tool - select Yes - select Accept - select Create installation media for another computer - select DVD ISO file - Save as local.
Execute the local WINDOWS.ISO file-right click-mount-select execute setup.exe-select don't use it for now-select keep personal files and settings-select Next-wait for the WINDOWS Repair installation to complete-reboot the WINDOWS computer.
