Disclaimer: I am not suggesting that this is the defacto way to upgrade this tablet to the Windows 8 Developer Preview, but this is what I did (so far so good, all the usual disclaimers etc)
The basic steps I took were:
- Back up the supplied Windows 7 installation using the instructions provided
- Install Windows 8
- Run Windows Update
- Download Windows 7 drivers from Dell
- Install the drivers
Installing Windows 8
- Download the Windows 8 image (DOWNLOAD)
- Mount the downloaded iso file (I used MagicISO)
- Run the setup program and follow the installation instructions given
NB I chose the 32bit O/S over the 64bit owing to the limited memory available on the device (2GB) and the fact that Dell supplied the 32bit version of Win7 with the machine, rather than the 64bit in the first place).
NB 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:
Download Windows 7 drivers from Dell
From the DELL support page identify your machine and proceed to download all the Windows 7 drivers:
Follow the instructions to download the drivers to your local hard drive.
Install the drivers
You should end up with a folder of drivers and applications similar to that below:
Run each application setup program in order, top to bottom, waiting for each to complete, with the exception of R297914 – this is the WIFI network driver for Atheros and caused issues with my system (I installed it but then had to roll back to the previous driver).
After installing all the applications reboot your system (you should receive a prompt to do so)
NB At the end of this process the tablet was performing well but I still have a couple of unidentified devices in device manager. (It should be possible to find drivers for these but at this point in time I haven’t done so – if you do so please post a comment at the end of this blog article)
