If you have an Enterprise Edition of Windows 8, such as the Windows 8 Enterprise Evaluation Edition, you can create a Windows To Go USB Flash Drive.
Go to the Metro UI page and type “Windows To Go”
Click on “Settings”
Click on “Windows To Go”
A “Create a Windows To Go workspace” window will open
If you don’t have a USB plugged in you will get a message
“Searching for devices”, and then you will get a message
“Can’t find a connected USB drive. Make sure you’ve inserted one.”
If you plug in a USB drive it will see the USB drive, the messages will disappear, and it will show the flash drive. I used an 8GB Flash drive and it showed it as 7.54GB.
The “Next” button was greyed out. I hope that it will not let me proceed because I don’t have a big enough USB drive, although it’s possible that even with a 32GB or 64GB USB drive, it still would not let you proceed if it was not a Microsoft Certified device.
I don’t have a 32GB USB drive, so I couldn’t try to set it up. Microsoft recomends Microsoft Certified USB drives. I looked up the Kingston Data Traveler Workspace – Windows Certified drive, and it was $137.00 for 32GB. They also have 64GB and 128GB for more money.
