I haven't tried this idea but it may also work. If others are in dire need to make this all work on a single large USB, it may be possible to create two partitions on a single USB one FAT32 and another ExFAT, and use similar steps above instead of using two USBs you will have to manage two partitions. Rsync -avh -progress /Volumes//sources /Volumes/WIN10_USB2

#USE PC TO CREATE MAC OS USB INSTALL#
The PC was able to boot from the FAT32 USB and it found the install.wim file (and whatever else it needed) from the exFAT USB without any additional voodoo, and completed the install successfully. It seems not to matter that some materials will appear on both USBs.

The task: make a Windows 10 installer USB for a new PC, when I only have a Mac (running macOS Catalina).

This is definitely a roundabout way and takes a bit of time (up to 2 hours to download the ISO, installing Windows on Mac using Boot Camp, Windows 10 Media Creation, and Windows 10 PC install) but it works.Īfter going through all the above headaches, and the sledgehammer-nut issues and the worry of security risks, I found a straightforward solution adapted from a post by "cerberus" on this forum/thread. Simply go through the process of installing Windows, go to the Microsoft Windows 10 page on your Windows partition and follow the instructions for creating a bootable flash drive (using the Windows 10 Media Creation Tool), and then use that USB to complete the Windows 10 install on your PC. I tried multiple solutions (deleting partitions, copying the install files to a new partition, lots of diskpart work, etc.) to no avail.Īs a backup solution (and what worked for me): you can always create a working USB by installing Windows onto your mac using the Boot Camp Assistant tool referencing the same iso downloaded from Microsoft. Booting up the windows installer from the USB was successful, but at the end of the installation I hit the "Windows could not prepare the computer to boot into the next phase of installation" error. This process did not work for me for whatever reason.
