When you download ubuntu Linux will your original os stay on another user?
Ubuntu generally creates a different partition on your hard drive, formatted with the EXT4 filesystem. Therefore, without special software, you cannot access your files on Ubuntu from Windows. However, you can access your Windows files from Ubuntu without any trouble. When Ubuntu is installed, you get to choose whether to boot into Ubuntu or Windows when the computer turns on. That means that you cannot be actively logged into both Windows and Ubuntu on the same computer. However, you can install Ubuntu on a virtual machine, making the computer run Ubuntu inside an emulator in Windows. This makes it possible to run Ubuntu while you are logged into Windows. I do not recommend it, though. Ubuntu users and Windows users are in different operating systems, so you cannot just switch between them like you can in Windows accounts.
