I installed Windows To Go on a 32 gB SanDisk flash drive today.
I first booted it on a system at work (HP TouchSmart). I left it for a long time, and when I returned the system was in Win7. I suspect it was because I left it sit at the "Enter your Product ID" page for too long.
Rebooted and it worked well. Discovering the hardware took a while tho'
The next boot was smooth and fast - getting straight into Win8
Biggest issue was missing chipset and touchscreen drivers.
Windows to go isn't meant to be used on typical USB media - there will be specific (basically an SSD inside a USB container with a USB plug) logo'd devices that will be supported for use under WTG. The drives that I've used that are actually WTG devices don't seem to have issues other than a Windows install would typically have - you have to inject needed drivers if Windows doesn't ship them. Not sure what your issues are with Windows Update, but perhaps I can help offline when you decide to give it another go .
Thanks cluberti! I'm most likely going to wait for the release of the logo'd device.
Does the logo'd device identify itself as a local disk or a removable drive?
I was assuming that the reason that updates wouldn't install was that I was using a removable drive.
I tried a few "tricks" to fool it into making it a local drive instead - but that's where it became too much trouble to muck around with.
I never tried to slipstream the drivers into the .wim file that I used.
I had installed touchscreen drivers onto the stick (I thought) - but they didn't seem to load on the WTG drive - and they never seemed to work on the touchscreen system that I was using. I can't find any trace of them on the WTG stick that I'm using.
