How to Install Windows 10 Technical Preview in VirtualBox

Part 1 of 2:

Downloading and installing Oracle VM VirtualBox

Visit https://www.virtualbox.org/wiki/Downloads and look for a list of VirtualBox platform packages. Now download the setup for your Operating System by clicking on the link right besides the package name. For this article, I have downloaded, VirtualBox 4.3.16 for Windows hosts. Make sure you download the latest version of VirtualBox for your Operating System. I am presently working on Windows 8.1.
Run the setup file you downloaded and click on Next.
On the Custom Setup Screen, you can leave the settings as it is and proceed by clicking on the Next Button.
Leave the Register file associations selected and click on Next. If you like to place a shortcut icon for VirtualBox on your Desktop and in the Quick Launch Bar, leave the first two boxes selected.
Now click on Yes to ensure that VirtualBox is able to access your Network Interfaces. This will help you to access Internet and other network resources from Windows 10.
Click on Install. Now sit back and chillax while VirtualBox installs on your system. Depending on the security settings on your Operating System and available system drivers, your Operating System may ask you to allow or deny the Setup proceed and install few drivers. This is essential for your VirtualBox to let Windows 10 access hardware and other resources on your host operating system (the operating system you are using right now). You may choose to accept and install them.
Once VirtualBox has been installed on your system, you can then select, Start Oracle VM VirtualBox if not already selected and then click on Finish.
After the VirtualBox opens up, minimize it or keep it open. We will come back to this once we download an official copy of Windows 10 Technical Preview. We are now ready to download and install Windows 10 Technical Preview on our VirtualBox.

Downloading and Installing Windows 10 Technical Preview

To download an official copy of Windows 10 Technical Preview, you first need to be part of the Windows Insider Program. To join the program, visit https://insider.windows.com and click on Join now.
Now login with your Microsoft account. If you do not have one, you can click on Sign up now to create one and then go back to the previous step of this tutorial. If you were already logged in the Microsoft account, you would not be shown a Sign in page.
You will now be taken to Accept the Terms of Use and Privacy Statement page. Once you have read this page and all the relevant information, you may choose to click on, I Accept and then proceed with this article.
Click on install Technical Preview.
Scroll down to the Download links section. You will see a list of available downloads. Depending on your language and your system architecture you may download one of those files. If you are not sure whether you are working on a 64-bit or 32-bit machine, you can download the 32-bit (x86) file by clicking on the Download link right besides it. To make use of 64 bit you may need to enable Virtualisation from your BIOS. If you are not aware of these concepts or do not know how to do it, download the 32-bit (x86) file for a safer bet. In this article I have picked English 64-bit (x64) as I am working on a machine with a 64-bit processor with a 64-bit Operating System.
Once your download is complete, open Oracle VM VirtualBox and then click on the New button.
In the Name field enter, Win 10 Tech Preview and then select Microsoft Windows as the Type. Now select Windows 8.1 (64 bit) as the version. If you had downloaded a 32 bit Windows 10 Technical Preview file then select Windows 8.1 (32 bit) from the list. Now click on Next. If you had downloaded the 64 bit Windows 10 Technical Preview file and if you do not see Windows 8.1 (64 bit) in the Version list then you might need to enable Virtualisation in your BIOS. If your are not aware of how to do so, you may search for a tutorial using your favourite search engine or go back a couple of steps in this tutorial and download a 32 bit (x86) Windows 10 Technical Preview file.
Leave the memory size to its recommended value and click on Next.
Select Create a virtual hard drive now and click on Create.
Select VDI (VirtualBox Disk Image) as the Hard drive file type and click on Next.
Pick Dynamically allocated and click on Next.
Pick a file location for your Virtual Hard Disk if you wish to change the default location. Leave the size of the virtual hard disk to its default value and click on Create.
On the Oracle VM VirtualBox select Win 10 Tech Preview Virtual Machine from the list if not already selected. Now click on Start to boot up our Virtual Machine.
You will now be asked to select the start-up disk. Click on the browse folder icon.
Select the Windows 10 Technical Preview image file you had downloaded and click on Open.
Once you have selected the image file click on Start.
This is it... This is what we have been waiting for. Just a few more steps and you would then be using the new version of Windows! Click Next on Windows Setup running on your Virtual Machine.
Click on Install now.
Read the License terms and click on Next if you wish to proceed.
Click on Custom: Install Windows only (advanced).
Proceed by clicking on Use express settings. If you wish you can click on Customize and follow the onscreen instructions till Windows 10 has been installed. In this article, we are following the Express Settings.
