    In the past on my MBP, I've divided the hard drive in half, (half Mac, half Windows) and at home rely on dual external hard drives for Mac data storage and backup, and while traveling bring two portable drives, one Windows and one Mac. This has worked well for me and it appears I'm easily dissuaded by your report, I'll probably do this again. :)

    I just installed Windows 10 on a Sandisk SSD USB3.1
    on my new MacBook Pro late 2016 and I still don't see
    advantages install Windows on external drive.
    I have used creation with WinToUSB.

    Speed is ok and everything work well but I still prefer my
    Windows 10 on internal drive together with MacOS
    both in native mode.

    From a portable aspect, there is a convince of booting into Windows without having to plug it n an external drive. If anything the advantage would be freeing up more for internal drive space for The Mac OS because when it comes to SSDs, Apple is chincey on size for their price.

    In case when you have a small disk of course on an external disk is required.
    And this I mean to those of 64GB or 128GB but one of 256GB is ok and one of 512GB
    it's perfect for both systems.
    I've seen a lot of people with those big disks installing systems on an external disk.
    For this reason I say that it doesn't make sense do it on a large disk.

    I with two system on 512GB internal disk I'm ok
    Didn't even need external disk.
    I only use one external for backup and large video files.

    Of course everyone should do it as it need for the best personal usage ;)

    Win to USB looks interesting, what is the difference in the free version and the one you can purchase,
    I assume there are restriction ?

    Is the quoted method by yjchua95 above still the best way to windows on an external drive?

    I did it a few months ago on 10.11 for a 2015 retina iMac and it worked perfectly, and the drive still works perfectly in 10.12.2. I don't think any of the changes in Sierra should affect yjchua95's instructions.

    I'm about to try this but was wondering what is bios-csm and UEFI? I have a 2016 15 rMBP and bought a Samsung evo 850 with a USB c enclosure. I have bootcamp installed on my Mac and plan on copying that.

    Firmware, UEFI is the new standard and is replacing BIOS. Your 2016 mac has UEFI.

    I need some help...

    I have a Mac Pro (2013), and I have an installation of Windows 10 Pro running in a Boot Camp partition on the internal PCI SSD. That works fine.

    I then used Winclone to clone the Windows installation onto an external ThunderBolt SSD. I followed the directions from Twocanoes, regarding format etc., but it does not work. However, when I connect the ThunderBolt SSD to my MacBook Pro (which does NOT have a Boot Camp portion on it), it works just fine. The Windows installation shows up in the boot menu. When I connect that same ThunderBolt to my Mac Pro, it does not.

    I have tried with a Boot Camp portion created on the Mac Pro, as well as without. I have disconnected all other ThunderBolt units on the Mac Pro, but alas...

    I simply cannot understand why the external ThunderBolt SSD containing Windows 10 will show up on the MacBook Pro, but not the Mac Pro. What can be the difference?

    In doing this on my iMacs, I found that Windows boot could not handle 2 installations at the same time, and I had to delete the internal installation in order to run the external Thunderbolt SSD installation. I always made a couple of WinClone backups before deleting so I could be confident that I would be able to recreate the internal one if necessary. I think you also need to disable SIP when you run WinClone write, but that was probably in the guide you followed.

    However ... when I started the External Windows Installation, it would appear to boot ... but I found that I was actually running the internal installation. Of course, deleting the internal copy eliminated this problem.

    I did a similar thing with my cMacPro where Windows SSD is "external" on a PCIe card in one of the slots.

    Hope this helps ...

    Thanks for suggesting this, but I have already tried that. I blew away the internal Boot Camp partition, and the external ThunderBolt SSD installation will still not show up when I boot on the Mac Pro, but it does when I use it on the MacBook Pro???

    I also found that I had to boot/run the internal installation with the external enclosure attached so that Windows would load the driver for that enclosure and include that in the image I WinCloned to the external SSD.

    I can't explain why yours works on the laptop as that would indicate any driver required was present.

    Has anyone figured out yet how to update the Windows on a USB3-SSD to a newer version, e.g. 1511->1607, without wiping the drive and re-installing the whole thing - that is, by keeping your apps etc. intact as if it was a PC?

    Would perhaps temporarily plugging the SSD with Windows on it via SATA to a PC just to update it work? Or would that break anything once you brought it back to use on a Mac via USB3?

    I have just successfully moved my Bootcamp onto Samsung T3 external using Winclone and the regedit method. It was much easier and quicker than I expected.

    Posted a separate thread here before seeing this thread.

    One reason for putting Bootcamp on an external is that it enables partitioning of the internal.
    I think it is still the situation that the MBR will not boot with more than four partitions. In a standard installation there will be:

    EFI
    Recovery Partition
    Macintosh HD
    Bootcamp

    ......which does not allow the Macintosh HD to be partitioned.

    I know I fell foul of this a few years ago, but not certain if it is still true...anyone confirm?

    Since I moved my Bootcamp to an external I have partitioned my internal and Bootcamp still boots (I was slightly concerned there might still be a problem).

    hello,

    I've changed my mind since my obsolete MBPro 15" mid 2012 cannot launch Winows in UEFI and staying with the old crapy MBR is unreliable because very fragile and prone to be damaged...
    So at last Xmas i bought from GEARBEST Hong-Kong a fantastic PC laptop the XIAOMI Notebook Air 13.3" built on a Skylake intel mother board with a secund SSD slot at $680 only.
    This fantastic Windows laptop is a real MBAir killer because it's a bang for your bucks.
    I enjoyed playing Formula1 Grand prix 2016 with a vintage USB Logitech Momo Racing Force feedback wheel bought in 2002!
    My old MBPro 15" is now my spare secund machine in case something bad occured on my XIAOMI laptop!
    I decided to buy eyes shut this terrific laptop since previously when my iPhone5 had it'screen poping out like a Microsoft Surface, i was rejected from Apple Service...
    So, i put 4 drops of SuperGlue at each corner of the screen and put the iPhone5 between 2 pieces of wood firmly screwed and that's it for a DIY fix.
    But instead of throwing huge money for another iPhone6 or 7, i purchased a XIAOMI Redmi3 Pro from GearBest at $120...
    YES this Android phone is perfect and a bargain!
    APPLE is heading direct in the wall because you must be CRAZY to shell out $700 for a phone and more than $2000 for the latest MBPro 2016...
    I can testify that Windows10 is now a great system software: it boots up blazingly fast and everything 's OK
