Hello,

I've just able to install windows 10 on my external thunderbolt 3 nvme ssd by watching 9to5mac's this video;


I just used Parallels instead of VMware since it doesn't let me connect tb3 drive.

However, when I boot windows 10 from the external drive for the very first time, it always crashes giving me this blue screen;

I have already disable secure boot from macOS. Any suggestions?

I missed your backstory. Why are you doing it this way instead of just bootcamping some space on your mac hd and using an external ssd for all of the windows data? Is your internal drive too tiny?

Yes, my internal drive is quite low on capacity and also didn't want to divide the ssd.

you didn't really tell me the size of the drive but I guess you know you only need 25-30 gb for windows 10 and everything else can be on the external ssd. if you go through with DaisyDisk, you may be able to clear some kerfuffle and get some of that space you need.

Paragon Softare sells the Mac Toolbox that gives you CampTune (resize your bootcamp at will), NTFS for Mac, APFS for windows, and HFS+ for windows, so it does not really matter what is where when you are bootcamped. You can use the entire hard drive and still have an external for whatever data you want.
