I have a no-name tablet which can dual boot to Win 10 or Android 5.1. I have no use of the WIN 10. Is there anyway to delete WIN 10 and make it Android only ? On desktop with WIN and Linux. All I have to do is use a partition manager to delete the WIN partition , make the Linux partition bootable and extended the Linux partition to use the space left by the deleted WIN partition. Is this similar in my case ? Is there such partition manager Apps for Android ?
