If I may jump in, you can download the media creation tool from MS here assuming you have Windows 10 or from here if Windows 11. With that tool you can create a Windows  bootable installation flash drive . And with that you can install the OS. This YouTube video will detail the procedure of a clean install. The procedure for Windows 10 and 11 is the same.
I have read this thread... [URL] But my recovery key for that laptop is NOT on my MS account. I have 4 desktops and 3 laptops. Need a solution.
