  1. This will work if after the process I plug the SSD drive into a Windows Laptop? I tried everything on my other windows laptop and it says operating System not found and it doesn't access the BIOS. I plan to install a windows on an SSD drive using my mac to plug back into my other windows laptop.

    Thanks for your video, any help will be welcomed

  2. Hi all, I hope you can help me.
    I did all the steps correctly. Just before I should restart to windows, I got the following error:
    First I went to System preferences —> Startup Disk
    I selected my bootcamp windows folder which shown up. After clicking at restart it said:
    "The selected disk can not be used as startup disk"

    I bought the new Samsung Portable SSD T5 for this. I have the 2017 MacBook Pro 13".
    Can someone please help me 🙁 🙁

  3. I cannot get Windows 10 to reliably mount a USB3.1/Thunderbolt3 volume. Windows sees the device, but mounts/unmounts the volume over and over and over again. It's very frustrating.

  4. Windows 10 wasn't able to connect to my hard drive. The hard drive only shows up on my mac screen. Please help. How do I make it connect to windows and not my mac.

  5. Hey, I was wondering if anyone could help me? I installed Windows successfully about a month ago, but then it stopped working. I'm trying to install it again, but my VMware Fusion trial is now over. Is there anything else I can use as a substitute (or is there a way to reset my free trial)? Any info would be great, thank you!

  6. Awesome! This was exactly what I was looking for. Brilliant step-by-step video. Cheers!

    I did, however, run into a snag. My VM Windows didn't initially recognize external usb 3.0 hard drive. Doing a little digging around in the VMware forums, I found several others with my problem. Apparently it was a firewall issue on Apple's part. To resolve this issue, I went System Preferences -> Security & Privacy -> Firewall -> Unlock (bottom left corner) -> Firewall Options -> and then ADD VMwareFusion application. Make sure you click first two boxes allowing the application to accept incoming connections. After a quick restart, everything works perfectly!

    My MacOS version was 10.13.4 and I was installing Windows 10 Professional.

    Thanks again for an awesome video!

  7. For those who may have a MacBook Pro Late 2011 17" here are my findings. Via the Thunderbolt port I have a Seagate Barracuda 7200 HD, spinning HD. VMware Fusion latest version does not recognise the Thunderbolt connection without further jumping through hoops? Connection via USB 2.0 on the MBP it does? However WintoUSB will not install the Windows software my last reply. I stopped it after 40 mins? There are many variables? Great tutorial if you have the same setup, computer etc.

  8. Installing Please wait? WintoUSB still at 0% after 25 mins? I am connected to a Seagate Barracuda 720 spinning drive via USB I guess after 40 mins and no movement and the drive quite its not working? Any advice

  9. Hey if anyone could help me that would be awesome, I completed every step of the video up until the point where you put the windowssupport onto the ssd. When I went back into mac it won't show up so I went back into the the VM and it wont show up there either. The ssd is has just completely dissapeared and now I'm worried that I've bricked it.

  10. Great tutorial! @9to5Mac

    For those who have High Sierra and VMFusion 10.

    1. Before you Erase your SSD Follow this instruction.

    In Disk Utility, near the close/minimize/fullscreen buttons, you can see a "View" mode drop-down menu. Set the view mode to "Show All Devices", then you'll see the "root" drives. Click on a root drive, and then click on the "Erase" button. Now an option to change the "Scheme" from Master Boot Record to GUID appears in the Erase subwindow. Now you will see EFI partition on your SSD.

    2. Detecting SSD on Windows 10 (VMFusion)

    VirtualMachine > USB and Bluetooth setting -> choose Connect to Windows.

    3. If you are doing this on Macbook you will need a wired mouse or keyboard until you install the drivers.

    That should be it. Hope this 3 instruction helped.

    Tested on MacBook Pro 13 (2017), Samsung T3 250 GB SSD 4/11/18

  11. Hi Jeff, is it possible to do multiple partition to install other OS in external drive. Also Let say if I have 2TB of hard drive can i use 1TB for windows bootcamp and other 1TB as storage.

  12. My Mac turned to a black screen during the setup process. Each time I have to erase the drive again and re partition it before I can try it again. It keeps happening.
    Any recommendations? Is my HDD crashing?

  13. I had some issues when I were supposed to run setup.exe for BootCamp. I got an error window that said nothing.. So I didn't get the drivers or BootCamp.. I fixed it by updating my MPB and then download a new WindowsSupport folder when in MacOS, put it on a flashdrive because I couldn't write on bootcamp-drive from MacOS. Then in Windows replace the old WindowsSupport folder with the new one. Boom! It worked fine after that!

  14. Hi! For anyone not able to boot, I found the solution. In High Sierra, Apple changed disc utility so that to format the drive as GUID you must click view (under the close, minimize, fullscreen buttons) and select show all devices in the dropdown menu. Then erase the flash drive as GUID. Hope I could help because I had to do quite a lot of digging online for a solution.

  15. win2usb couldn't finish the installation. Can't copy WIM file!! then I remembered why I move to Mac… No help, pointless error message, try & error as hell… I'll game on my mac!

  16. Hey I have an issue. I have the high end MacBook Pro 15” 2017. I have done exactly as per your video. Everything went well. When in the end you advise to reboot the computer into Windows 10 for the first time, I did so. Everything ran good tell the screen where I need to setup my region. So I needed to use my keyboard, trackpad and mouse. None of them work!… the only thing that I have done differently is I had uninstalled VMWare before rebooting. Please help
