I did think of a way. I have a test setup that was already
pretty close to doing this. But, I could not get it to work.
2) Install VirtualBox (package manager).
None of this is needed!!! OP has Ubuntu and wants to make a Windows
bootable installer on a thumbdrive then none of all these suggestions
are needed. All the OP has to do is download the ISO from M$. Obtain a
thumbdrive large enough to accommodate the image. Stick it into a USB
slot. Start application Startup Disk Creator. Yes it there. 18.04 and up
'Show Applications' or older version click the BFB, Big Friggin Button
to open Dash. Type 'Startup Disk Creator' and start app. Point to ISO,
point to thumbdrive, CREATE. That is it!
I knew this type of follow up was coming. It was only a matter of time.
Linux has been able to burn ISOs for probably longer than Windows has.
Thanks, Jonathan. That was excellent.
