Here is how you can install a virtualized copy of Ubuntu in Windows 8:
- Check if your CPU supports SLAT and install Hyper-V.
- Open the Hyper-V Management console from the Start Screen.
- On the right hand side, in the actions pane, click on New and then select Virtual Machine from the context menu.
- If this is your first time using Hyper-V, a Before You Begin screen will appear, just click next to continue, then give your virtual machine a name and click next.
- You can choose how much memory you want to assign to your virtual machine, if you want decent performance I wouldn’t recommend giving your virtual machine any less than 1GB of RAM.
- If you have set up network connectivity previously, perhaps for other virtual machines, you will be able to select one of the networks now. Then click next
- Go ahead and use the new VHDX type virtual hard disks, these allow for up to 16TB virtual hard drives, so choose a size within that range and click next to continue.
- You will likely be using an ISO to install the OS, so switch the radio button to an Image file and hit the browse button.
- Then go ahead and select your Ubuntu ISO.
- Now click the Finish button and wait a few seconds while your virtual machine is created.
- Now you will need to start the virtual machine which can be done from the right-click context menu.
- Once you see your virtual machine start, double click on it to open the console.
That’s it. You now have a running copy of Ubuntu in Windows.
