install bootcamp on external disk
Hi. Yes. I know there are several threads with the same topic. But the information there is all messed up.
I want to install a bootcamp partition in a SanDisk Extreme Pro USB 128GB 3.1 stick. Is it possible?
I made an image of a bootcamp with Winclone and the restore the USB drive with that image. I deleted then my bootcamp partition freeing space in my internal SSD. Turns out the USB drive is not bootable. So I erased that image and started from scratch following the guides in the master thread.
It didn't work. I tried everything. I've even parallels, I tried that way. Such a mess, and 3 hours of waste of my time.
Does someone knows a well guide tutorial to make a bootable bootcamp in an external drive?
Also, how do I apply later the patch in order to Windows recognizes my eGPU?
Unlike macOS, Windows needs a special install method for USB.
There are many guides. I forget which one I used - probably not any of these:
There's a newer version at
Here's some other links:
Used this guide two days ago - can confirm it works.
@aj_scarcella, Thanks, I will try in the weekend. Such a bummer have to install virtual boxes and stuff. Windows is such a pain in the...well, y’all get it right 😉
Yeah, it is a bit irritating but this is the most efficient and least obtrusive method I know of. Previously, I had to have an existing Windows installation active so I could do a deployment managed install onto the external drive which is a much bigger pain in the butt than this. 😛
@aj_scarcella, Ok, now I'm in the process of completing the guide.
Previously, I was using reFind to boot and get the eGPU recognized. What method you you use?
eGPU for me is recognised without any modifications, short of disabling some Unused PCI-to-PCI Bridge devices in Device Manager. I do physically have to swap my monitor over to the eGPU to get applications and games to run off it, though (only on the Windows side of things - I use Purge Wrangler on MacOS which feels about as native as it gets).
@aj_scarcella, I’m done. Finally the installation didn’t went through. Then I read the 20 comments below. Not a single success and all kind of errors. I speak for myself when I say that the guide is poorly executed. First I couldn’t create the bootcamp file. Then I got stucked in the installation when you have to close the window before the restart. Too much hassle. I tried again and It says that the bootcamp file is already created, I can’t seem to find it anywhere. That’s it. This and other ones are the reasons that keeps me away from Windows.
@aj_scarcella, I don’t know. It got stuck in the reboot of the install. The guide says you have to quit at this point and close the window of virtual box. It didn’t work for me.
Thanks for the great help. But I’m starting to believe that bootcamp in external disk is not a viable option.
