Aliexpress(not sure).

It was bought around 2014.

At the boot menu i can see both icon (win and Android) but only windows is loading. When on Windows file explorer i look into the available drives, there are 3, 1 for Win OS and other 2 (13GB and 127MB) that are empty. Is possible to reinstall the Android ?
