It is possible to accidentally erase your hard drive and install only Linux but the prompts are pretty clear and try to not let that happen.

Live CD's have come a long way and give you multiple options on how to use Linux. You have to ensure that your boot order is set to check the CD/DVD drive for an operating system before the hard drive through the BIOS options. If it says its enabled then click to Uninstall the RealTek (DO NOT check the box to uninstall the drivers). A Linux Live CD however, stores the entire operating system on the CD including drivers and software so that windows files are not even running. In the Device Manager, RIGHT click on the entry for the RealTek and one of the options in the drop down menu will be disable (if its enabled) and enable (if its disabled). Flash video on various sites plays only for a second or two before stopping, although the file continues to load in.

The emulated Linux machine doesn't have direct access to the hardware, it has to ask Windows to access the hardware. The Sound Preference panel says 'No Input Devices Found' and 'No Output Devices Found', and the volume slider is grayed out, set a max, with a grayed Mute box ticked. The Virtual Machine is running on top of windows like any other program and emulating a separate computer but still relies on Windows to run its processes.
