If you’re on windows and have a USB-C port, you can always use rufus to create a windows-to-go installation straight to the expansion card! This doesn’t require enterprise unlike the official way. 
How to create a windows-to-go solution with rufus: A guide.
First, download rufus.
Go to this webpage, scroll down and click Rufus 3.x
Which one do i choose?
- Portable → You don’t have to install, instantly works on any 64bit system
- Normal → Installs straight to your pc, always having an icon in the search tab.
Secondly, install rufus
Look in your downloads folder for an application with the name rufus, double click it.
An ‘execute as administrator’ window should pop up, click yes. → Input your password administrator’s password if you’re a normal user.
You should have a grey window with a few options.
Plug in your drive
I don't have an ISO yet.
If you don’t have an ISO ready, you can download it via rufus. Otherwise you can skip this part!
Click on the little arrow, a selection window should pop up, click download, then click the button again once the window disappears.
Select the windows version you want, in this case Windows 10 21H2 build 19044 revision 1288
(Keep clicking continue until you get to this part)
Select the download location of your ISO, in this case c:/users/yourname/downloads
Wait for rufus to download your ISO, this can take a while depending on your ISP.
End of the downloading ISO part Continue to next part.
If you do have an ISO, you can continue from here on.
Select your drive which you plugged in before, if you haven’t do that now
(Your drive automatically gets formatted by rufus. So watch out that you plugged in the right drive!)
Load the ISO into rufus by clicking select and then selecting the ISO with file explorer. If you downloaded an ISO it should just get loaded in once finished, if not select it from the place you chose to store it.
Find your ISO.
Click ‘image option’ inside of rufus, a window pops down giving you the window-to-go option.
Now click ‘start’ and select the version you want to use.
In this version (3.20) you can also add a couple of optional add-ons!
(This gets prompted after the previous step)
But, what are these?
- Skip data collection → Turns off inking, advertising ID, … also the log on screen that you get on a fresh window install prompting you for your liver if you aren’t careful enough clicking the right buttons.
- Prevent windows to go from accessing internal disks → You won’t be able to access hard disks that are hard mounted in the computer, in the case of the FW laptop your m.2 SSD.
- Copy regional info and local account info-> Use the same keyboard / language as your current account and copy your username and password to the windows-to-go installation
(This doesn’t work with online accounts eg. your Microsoft account)
I recommend these settings, although you might want to turn off accessing local disk. I just turn it on so I can use and see the steam library / files on my linux install. Could also be handy if your computer hard crashes and you end up in an unrecoverable state to format your disks like you would do in a linux live enviroment.
Click on ‘OK’ if you’re absolutely sure about formatting the drive to put windows-to-go on it.
Now you’re absolutely done, sit back and relax while rufus formats and applies the windows image to your drive!
