Hi,
Thanks for your post in Microsoft Community.
I understand that you have encountered the problem of redirecting to the Windows installation interface after installing Windows.
The Error 1962 No Operating System Detected prompted after unplugging the USB is usually caused by not enabling CSM in the BIOS settings.
You can try enabling CSM in the BIOS and setting it to UEFI first.
Unplug the USB when Windows installation is complete and requires a reboot.
Again see if you encounter this problem.
Let us know if it works.
