The last Windows I installed was Windows 10. I was trying to install onto a SATA SSD, while keeping my pre-existing Linux installation on the M.2 SSD intact. This took me an unreasonably long time and lots of failed attempts, and in the end, the only way I could find to make it work was to first physically remove the M.2, then install Windows, then add the M.2 back again. Which sucked a lot, because M.2s are really not optimized for easy or frequent installation and deinstallation.
