Windows 10 is a very early version, so it is not suitable to cover your existing operating system —— especially considering that this will make Windows Media Player unable to play DVDs and upgrade from Remove Windows Media Center from Windows 8.1 Professional.

Installing in a virtual machine is the easiest option. With the help of Oracle's free virtual machine tool Grad VirtualBox, you can experience Windows 10. The configuration used to install the system in a virtual machine is almost identical to that of Windows 8. Users should not encounter any problems during installation.

If the installation fails, then try to adjust the following configuration. After completing the initial setup of Windows 10, open the Settings of Virtual Machine Tool > System Menu. Under the "Motherboard" tab, make sure that the box for EFI (Special System Only) is checked. The same is true for the "PAE/NX" option under the "Processor" tab.
