Installing the Windows 8 Consumer Preview on an Asus EP21 Slate / Tablet

Product Image

I’m not going to labour the point but the installation of the Windows 8 Consumer Preview is a lot easier than my earlier post relating to the Dell Duo!  That said, the steps are essentially the same:

  • Back up the supplied Windows 7 installation if desired*
  • Install Windows 8
  • Run Windows Update
  • Download Windows 7 drivers from the ASUS Site
  • Install the drivers

* I say if desired as unlike the Dell Duo the Asus comes with a Windows 7 restoration disk.

Here are the steps I took in a little more detail:

Installing Windows 8

NB I used a USB Keyboard which I left connected throughout the process in order to make any text entry (WiFi passwords etc) easier, I also copied the Windows 8 key onto the same USB stick I used for the update process so that all I had to do was copy and paste it when requested.

  1. Download the Windows 8 image (DOWNLOAD)
  2. Mount the downloaded iso file (I used MagicISO)
  3. Run the setup program and follow the installation instructions given

NB I chose the 64bit O/S over the 32bit owing to the generous memory available on the device (4GB) and the fact that ASUS supplied the 64bit version of Win7 with the machine, rather than the 32bit  in the first place).

An alternative methodology might be to burn the downloaded image to a DVD Drive then utilize an External DVD Drive instead of using MagicISO.


Running Windows Update

This is essentially the same process as for Windows 7 – from the Win8 menu choose Control Panel and walk through the following screens before finally running Windows update:




NB You can also simply type ‘control’ when in the Metro desktop interface to switch to the Metro control panel, and from there select ‘windows update’

Downloading Windows 7 drivers from ASUS

The consumer build of Windows 8 does a pretty good job of managing the drivers and software from the previous Windows 7 installation.  However it is worth keeping an eye on the 64bit downloads from ASUS in case there is a firmware upgrade or some updated device drivers that don’t make it through the default Windows update process.  The download page is located here:  ASUS support page


Performance Rating:Untitled

(Noticeably superior to the Duo as you might expect.)


Now that this device appears to be available at reasonable rates on eBay I have to say that it is probably the best choice in terms of value and performance for a slate type device at the time of writing (March 2012).  If you can afford it the Samsung series 7 Slate is probably top  dog, with the EP21 a close second and a definite winner in price terms.  The dell Duo remains a great choice for testing the waters and is certainly more than capable of running the majority of Metro apps currently available.

ASUS App Compatibility

Art Rage

Art Rage is bundled with the Windows 7 install of the EP21 and is a great way to show off the tablet oriented features of the device.  It loads fine but I found the functionality to be questionable under Windows 8.

(All the other apps supplied by ASUS appeared to work OK under Windows 8).


ASUS Applications

If you intend to use any of the Asus applications that came with the Windows 7 software it is a good idea to pin them to the new Metro desktop.  This can be achieved by holding down on the relevant exe file until the in place menu appears that has the option to pin. Most of these apps can be found under c:\program files\Asus\

Bluetooth Keyboard

If you find that Blutooth isn’t working properly try downloading the ‘Wireless Lan’ Drivers from the Asus Site:


Extract them and run setup – it will fail saying that this is the wrong version of windows.

NB UNISTALL any previous version if you see this message:image

Go on to the install :


A few of seconds you should get a windows popup asking if it worked ok – click no- re-run in compatibility mode.
The install will now run OK – I deselected the WLAN driver (as Wireless is working fine anyway) and let it install the Bluetooth stuff:


The Bluetooth icon appeared on the system tray – open the settings from here once the installer has finished and click the ‘allow devices to see this PC’ option (not sure if this is absolutely necessary ).
Then held down the Bluetooth button on the keyboard , went into the ‘add device’ option in the control panel and the devices showed up, connected first time and just worked.

  2. I’m very happy to say that today (8/21/2012) I received my EeeSlate Ep121. It came packaged with a full set of recovery discs, so backing up the system wasn’t needed – an extra step I was able to save 🙂 Then, I installed the latest release, Windows 8 Release Preview – and immediately after the 64-bit install, it did a Windows update, and then rebooted again – and voila! Every device worked flawlessly! All the sensors, etc. – nothing was needed. Now THAT is how to simplify an install – way to go, Microsoft! 🙂 – – Mike
