⚠️ IMPORTANT NOTICE: For the New Windows 24H2 Installer at 07.51 in the video, make sure you choose "PREVIOUS SETUP" from the bottom left when beginning and turning your Deck portrait to continue with the setup installer like mine in the video and "don't choose delete everything".
⚠️ If you don't press Previous Setup and wiped your partition instead with SteamOS booting into GRUB, do not worry and follow this guide to fix - https://www.youtube.com/watch?v=eUDbLkHDeGY
