As the the subject heading suggests, I am unable to run Windows 8 from an external SSD. Specs of the hardware: Late 2013 27 inch iMac Seagate STAE133 External Thunderbolt Adapter 1.5ft Thunderbolt cable 240GB Intel 520 Series SSD Goal: Run Windows 8 solely from external SSD, with not Boot Camp partition on the internal drive. Using Boot Camp, I installed Windows 8 on the internal drive. I downloaded all the updates for Win 8, updated the Nvidia drivers, and activated Windows 8. I was able to boot into Windows 8 without any issues. It was stable and perfectly responsive. With the goal of running Windows 8 exclusively from the external SSD using a Thunderbolt adapter, I purchased Winclone and followed these instructions: http://twocanoes.com/winclone/suppo...n-external-drive-using-winclone-4.3-and-later The Windows 8 partitions are visible. Using Boot Camp Assistant, I delete the Boot Camp partition on the internal drive and reboot. Upon restart, the Windows 8 partition on the external drive is still visible and I select it. Then the Windows 8 start-up screen appears with "Welcome" then "Preparing Windows" for several minutes. Then a black/blank screen with a visible and moveable mouse cursor appears. Nothing else happens. I reboot the computer again, same problem. I've tried the above same procedure three times (the third time using a pre-release version of WinClone 4.4), to no avail. ANY suggestions would be greatly appreciated.
