This question already has an answer here:

I know there are a dozen other threads on this, and I've read through quite a few of them, but none of the methods outlined in the answers seem to work for me.

I've got Parallels Desktop installed with a working Windows 10 installation running in it on my High Sierra boot drive, but I want to install a native Windows 10 partition under Boot Camp for various reasons. However my main hard-drive is a RAID 0 (Fusion Drive) configuration, and Boot Camp says that's a no-no.

I've got this external Thunderbolt SSD that's 128GB that's just sitting there, waiting. But Parallels only sees it as a Network drive, and won't connect it "directly" to the Windows 10 virtual machine, so I can't do anything with it within Parallels. I have the Windows 10 install ISO, and I've written it to a 16GB Flash Drive. I think I can get it to boot, but Windows won't install when I have multiple thunderbolt devices connected, or even to an external drive at all, due to the way Windows installation works.

I should add that I first tried to install Windows to a partition on my boot drive, but that didn't work. The partition I tried to create created for Windows to reside on was on the Fusion Drive; that is, that's where Disk Utility created it; it's residing on one of the external Thunderbolt drives I have connected to the Mac. (The Fusion Drive consists of the internal flash drive, plus three external Thunderbolt drives.) This did not work out.

So now I'm trying to install Windows to the 128GB external Thunderbolt SSD drive. Please help!

Here are the outputs of my diskutil list and diskutil cs list commands:

This question has been asked before and already has an answer. If those answers do not fully address your question, please ask a new question.

  • I believe a RAID 0 set of drives is different from a Fusion drive. So my first question is "Which is it?". Next, which type of windows installation do you prefer: Internal or External? I believe both ways are possible, but I only have experience with internal drives. I also need to know what is the model/year of your computer. Once you have updated your question, I will be able to better help you. Also, could you post the output from the Terminal application commands diskutil list and diskutil cs list. – David Anderson Nov 28 '17 at 18:58
  • FYI, if you want to insure I receive notification of a comment you post, it is a good idea to include a @David somewhere in your comment. – David Anderson Nov 28 '17 at 22:34
  • Sure, no problem. I'm running a late 2013 Mac Pro, quad-core 3.7GHz Xeon processor, with 32GB of aftermarket RAM memory installed, 256B internal SSD, dual 2GB AMD FIrePro D300 graphics cards, with four external hard-drives attached: Two LaCie BigDisk 6TB and a G-STUDIO 6TB, all three connected through Thunderbolt 2, and Western Digital BigBook 6TB connected over FireWire 800 through a Thunderbolt 2 converter. The "FusionDrive" consists of the internal 256GB SSD, the G-STUDIO 6TB, and one of the Lacie BigDisk 6TB drives as a single CoreStorage Logical Volume. – William Andrew Hainline Nov 29 '17 at 21:09
  • @David, I have edited my original post with my dIskutil and diskutil cs info, if that helps, and have included my computer info in the above comment. Also have asked some clarifying questions in the comment below on your Answer. – William Andrew Hainline Nov 29 '17 at 21:25

I have moved the instructions to the question: Is it possible to use Boot Camp with Windows 10 from an external HDD?

If these instructions fail to work, you can either pursue a third party tool or I can modify the instructions to install Windows to your internal drive.

  • When you say "The UUID's for 8 GB the 600 MB partitions should be EBD0A0A2-B9E5-4433-87C0-68B6B72699C7 and DE94BBA4-06D1-4D40-A16A-BFD50179D6AC, respectively," first of all, I think the grammar in that sentence came out a bit garbled. How did you in fact mean for that to read originally? And two — how do I set the UUIDs manually? Also, how do I "open a windows command prompt" once I've booted to the drive where the installation files are? Won't that just start the installation? – William Andrew Hainline Nov 29 '17 at 20:55
  • OH, I GET IT. You meant the 8GB AND the 600MB partitions. – William Andrew Hainline Nov 29 '17 at 21:51
  • Thank you for the detailed instructions!!! I will try this tonight! – William Andrew Hainline Dec 1 '17 at 10:25
  • @William: FYI, I have actually tested these instructions using a USB 3 HDD. – David Anderson Dec 5 '17 at 0:37

I wrote a blog post a while back, that might help LINK

    If possible, could you summarise the key points of your blog post? This helps ensure your answer is still helpful in future in the event the link breaks. – Monomeeth Nov 29 '17 at 22:42
