I've still not managed to install Windows 10 via WDS. Installs fine after you do the above fix I sent (which only happens on some PCs), but after it does that, it boots up to the "Hi" and selecting time and date and region, go though the settings and then the next screen is the custom or express settings. Once that's been selected it will say restarting in a moment, restarts a couple of times and then goes back to the selecting time and date and region settings. Not got any further than that, but the settings are the new time and date settings that I've selected, so the date is now set to UK not US, which is strange.
