So I wondered. I could not use the Windows 7 tool to copy the ISO file to USB. It reported the Windows 8 ISO is not the right format. So what then? Burn a DVD… aaargh.
Somewhere on the consumer preview site http://windows.microsoft.com/en-US/windows-8/consumer-preview it mentioned that the setup would allow you to install from USB one way or the other.
Thus I started on my production tablet PC the downloaded Windows8-ConsumerPreview-setup.exe file to see what would happen. No guts no glory!
The setup started with a check of available apps and hardware. Gave me the list of what is OK and what needs an upgrade. Bravely I clicked next. It offered the product key. After that I stopped. I canceled the setup.
Now in the mean time it had installed on the desktop an shortcut Install Windows. OK, before you hit that icon, make sure you have a USB stick with sufficient memory inserted in your system. I had this due to the fact I had previously tried the Windows 7 tool to unpack the ISO on the USB stick.
And now it is happily downloading the installation bits to this USB stick…
Hope this is useful to somebody
