Hello July,
When upgrading my tablet from Win 8.1 to Win 10, windows system told me that I don’t have enough memory space to install win 10 and give to me the option that I can use a micro SD card memory to install win 10. I choose this option and insert a 32 GB micro SD card into my tablet. Installation of win 10 run thru smoothly.
My tablet is a Dual Os system. It runs Windows 8.1 and Android 4.44 . After upgrading my tablet from win 8.1 to win 10 (with reserved windows icon), my tablet doesn’t work anymore with Windows OS. It tried to boot up, then has a black screen. When I switch it to Android 4.44 system, it works perfectly.
Can you tell me what is the problem? How to solve it? Can I reinstall Win 10? How to do it? Or Can I rollback to the previous OS and how to perform the rollback?
Thank you very much for your help.
