After months of procrastinating on it, I finally clean installed Windows 11 and Debian 12 (Linux) on my personal laptop. I intend to use Debian by default as my daily OS and dual boot to Windows if needed. If you want a clean install of W11, check out Windows Utility (Chris Titus Tech) and its MicroWin functionality. Oh and Ventoy is awesome: a single flash drive with all the .iso installers you need, readily bootable.
