As you know, Windows 8 PRO comes with “Hyper-V” server as an option, so you can use it in order to get your hands on Ubuntu inside of your favorite Windows desktop. Here, I share our experience in “Ubuntu 12.04.2 LTS” installation on my Windows 8 Pro x64 desktop.
First of all, you need to get ready your Hyper-V in the Windows 8. In order to get it, just enable it in :”Windows Features” dialog box, which you can get from “Programs and Features” window by clicking on the left side panel link: 
and you get the dialog box as follows:
where you can enable “Hyper-V” option and click Ok.
As soon as the system installed the program, check in your BIOS, that virtualization is enabled for your processor.
Next step is to find the Hyper-V in Windows 8, to do so, just type Hyper-V into the start system of Windows 8 and you get the following:
and just hit enter to get the program running.
In the Hyper-V Manager, create new Virtual Machine, by selecting parameters as follows:
- RAM – 2Gb;
- HDD – 90Gb;
- The rest is by default;
But in order to get the network adapter working, you need to do the following (credits went to this post):
- In the Hyper-V Manager, go Action->Virtual Switch Manager:
- Select “External” and then “Create Virtual Switch”:
- Give the Switch a Name and then select the External Controller you use to connect to the internet (Ethernet, or Wireless NIC, etc,.)
- Select “Ok” or “Apply”.
- Select settings for your virtual machine and in the settings, select the “Network Adapter” where you are to select the switch you just created as follows:
By now, you can start the installation of Ubuntu, downloading previously the iso file from www.ubuntu.com. Don’t forget to choose the iso file: “Media->DVD Drive->Insert Disk…”, maybe you need to reset your victual machine right after the selection of the file and you get this screen:
After that you can follow the installation procedure, by using “Erase all disk and install Ubuntu” as a way to partition your virtual disk for the installation: 
and your installation is on the course…
