Hi, Reason to have an older version of windows 10 (1803 or 1809) is to be able to play forza motorsport 7. There's no cr... for 1903. I can't easily rollback to 18.. because no more windows.old file and after 10 days of upgrade to 1903. Can I dual boot 2 windows 10 versions? Can I install 1803 on an (external) drive, or usb and start from there? Do I need to disconnect my ssd with 1903 for that? Is there an other solution? (Then reinstall everything from zero?) = too much work with so many programs installed on computer and now on 1903. Thanx for any help or reference to a solution.
Or can I just switch in bios the startup drive containing 1803 and switching back in bios to 1903 ssd, when needed. Just having forza m7 installed and nvidia and thrustmaster wheel support on my 1803 or 1809? Can I make this work on an external drive?
You can I dual boot 2 windows 10 versions. You could partition your drive and install a second W10 on a new partition. You could also install a second w10 using a vhd file. Booting from an external disk/usb is not supported, unless you use a windows to go.
