Now give your new virtual machine a name and from the OS Type option, select “Microsoft Windows” for Operating System and select “Windows 7” for Version. Then click next.

Important Note: You have to select Windows 7 from version even if you are running VirtualBox on Windows 7 x64. Do not continue if Windows 7 (64-bit) is selected, otherwise VirtualBox will crash.

Now you have to allocate RAM for this virtual machine. We will recommend to allocate minimum 1 GB Memory for Windows 8 32-bit. Select 2GB if you have 4GB or more. We will continue with 1GB. Click next when done.

Once you have allocated memory, you will then be prompted to either load or create a start up disk. By default, the Boot Hard Disk and Create new hard disk options are selected. We will leave it untouched.

Now it’s time to make sure how much disk space you are going to give up for Windows 8. This is 20GB by default. We will recommend you to keep it minimum 20GB. Otherwise the system may fail to start. Also use the browse button (right to the virtual machine name) to select where the files will be saved. Select a partition with minimum space freed.

In the last step, you will get a quick summary of the settings you have selected. Click Create to begin creating virtual disk file.

  6. hi,
    the acceleration tab on Configuring VirtualBox For Windows 8 isn't available in my pc. pls help

  8. @Nancy -Gomez is right. you should check HAV before trying. Wait, a tutorial will be posted tomorrow.

  9. @Aghil
    have you checked for HAV on your processor?

  10. Virtual Box seems to have more success loading the Windows 8 image than either VMWare’s or Microsoft’s offerings. So, grab a Virtual Box if you haven’t already (why not? It’s free!) and create a new system, using “Other Windows” as the OS type. I don’t know what the minimum required specs are for Windows 8, but I gave the VM 4096Mb of RAM and 60Gb hard drive, which should be plenty. Choose to create a new start-up hard disk using the VDI file format. (More detailed instructions on these steps can be found at

  11. At last I got to be able to run Windows 8 on Virtual Box. It was my hardware problem first.
