This new version 1903 of Win10 requires min 8GB storage which I do NOT have. Please help for my following questions:
Should I download Microsoft ISO file to a SD card and install from there?
What I need to aware in order to keep the Android system because mine is a dual boot system?
Do I need the 25 characters Windows Product Key to activate the new version 1903 after installation from the ISO file? if no, what I need to aware and how to proceed from there? If yes, how to retrieve the product key?
After completion of installation, are there any drivers required to be reinstalled?
Thanks in advance.
