Windows 7 installs in 5 mins (4:49 actually) via USB 3.0 Key!
Adding the Intel SATA drivers to the boot image (boot.wim) appears to have worked. Windows Setup recognized the new drive (as well as the onboard 32gb ssd).
Unfortunately adding the intel USB 3.0 drivers to the boot image does not appear to have worked. Windows Setup immediately asked me to browse to the drivers. And couldn't see the usb 3.0 key. Fortunately there was a copy of the drivers on another drive. Setup was able to use those drivers and recognized the USB 3.0 drive after I manually browsed to them. Have a question out on an internal DL - will update if a solution is found.
As an aside I can't believe an order (for the SSD) placed at 8:30pm Thursday night was delivered by 4pm the next day (friday). If ONTRAC (amazon's delivery service) is the future of delivery then I fear for the fate of brick-and-mortar electronics retailers.
