A few weeks ago Microsoft released a new version of Windows, the Windows 8 Customer Preview. Probably you are curious to see what is new on Windows 8, many sites are saying that this new Windows is a system that will run on tablets, smartphones and computers.

First of all, download your ISO file on:

Windows 8 Customer Preview – 64 Bits (English)

Windows 8 Customer Preview – 32 Bits (English)

Windows 8 – Customer Preview other versions

After download it, you can install it normally on VirtualBox, I used 20gb for hard disk, 2gb ram and 128mb for video. But checking the VDI size, I got 5gb, so probably you can install it with 10gb for hard disk.

A few websites as ExtremeTech refers to some specific configuration to run Windows 8, on my installation, I just used VirtualBox default settings and it works, but if you have any problem during the installation, try to use them.

1 – System – Motherboard – Enable IO APIC
2 – System – Motherboard – CHIPSet ICH9
3 – System – Processors – PAE/NX
4 – System – Acceleration – Enable VT-x/AMD-V
5 – System – Acelleration – Enable Nested Paging
6 – Display – Video – Memory 128
7 – Display – Video – Enable 3D
8 – Display – Video – Enable 2D

Now install it normally and enjoy your new Windows 8
