Trying to make a bootable USB for Windows on a Mac? Here’s a simple way that worked for me in January 2024:

I have a MacBook Pro M2 running the latest macOS Sonoma. I am looking for a way to make a Windows 10 bootable USB on my Mac so I can fresh install Windows 10 on my newly built PC for my son. Does anyone know know how to do this? In the past, this could be done easily with the stock Built-in Bootcamp Assistant app but it is not available on Sonoma.
[Update Dec 12] The solution that finally worked is WonderISO app. Here is the online tutorial:

P.S. Still received notification from this post frequently. I did try the new suggested app but unable to open it, saying 'WinDiskWriter cannot be opened because it is from an unidentified developer.'
OK. Here are some instructions from Gizmodo that will put the ISO onto the flash drive with a Mac... they won't make it bootable though... read on...
Open a Terminal (under Utilities)
Run
diskutil listand determine the device node assigned to your flash media (e.g., /dev/disk2)Run
diskutil unmountDisk /dev/diskN(replace N with the disk number from the last command; in the previous example, N would be 2)Execute
sudo dd if=/path/to/downloaded.iso of=/dev/diskN bs=1m(replace /path/to/downloaded.iso with the path where the image file is located; for example, ./windows7.iso)Run
diskutil eject /dev/diskN, and remove your flash media when the command completes (this can take a few hours on slower drives)
Now... after you read all that, on the Gizmodo page it says that if you want to make it bootable you should use a utility called Live USB helper they link to (which isn't there any more) and use a Mac mounting tool (which isn't there either!) to force the ISO to mount on the Mac so you can copy the files over. So... that article may prove useful, but probably not. I can find other copies of Live USB helper out there, but they are all Windows executables.
One method that will work is to swap the hard drive out of the PC and into the Mac. Put your Windows 7 installation disc into the Mac optical drive, and install Windows 7 on that drive. Once it is up and running (don't worry about drivers yet), follow these steps.
- Run Command Prompt as administrator
- Type to Command Prompt:
%windir%\System32\Sysprep\Sysprep.exe, and hit Enter - In sysprep dialog that opens, choose “System Cleanup Action” as “Enter System Out-of-Box-Experience (OOBE)”, select “Generalize”, and select “Shutdown Options” as “Shutdown”. Click “OK”
- Sysprep generalizes now your Windows 7 setup and shuts down your computer. Do not run any other programs during this phase!
- Remove the drive from your Mac. Put it back into the PC.
- Boot the PC from sysprep generalized hard disk. You will notice Windows booting as if it was the first boot after installation, installing default and updating registry. One or two reboots are needed, depending on your system specifications
- When Windows finally boots up, you will need to enter all information as if this really was a new, fresh installation
All that is from here, but it applies in this situation a well, since you would be moving a Windows 7 installation from one computer to another. Considering that trying to make a Windows bootable USB stick with a Mac requires tools that either don't exist any more or are not being developed any more... this second method will most likely prove more dependable.
Assuming you have burnt your Windows CD into a ISO file with the tools like:
http://burn-osx.sourceforge.net/Pages/English/home.html
1. Jump into a folder here http://sourceforge.net/projects/unetbootin/files/UNetbootin/
2. Get the latest version of zip archive with the keyword "mac" in the filename.
3. Download and open it up on your Mac OS X desktop.
4. On Unetbootin interface, choose [Diskimage]->[ISO] and then select the Windows ISO file on your local hard drive.
5. Select the right USB Drive and then click [OK] to start writing ISO data onto your USB drive.
Once done, you're ready to boot your computer with this bootable USB drive, like a DVD installation disk.
I was searching for the best solution for hours, and then even ran into issues within the dated solutions that I saw here. I even tried creating a virtual machine, but my MacBook’s old 4 GB RAM couldn’t handle a Windows 10 VM (to be compatible with the flash drive).
I thought I’d share to save anyone else some trouble, at least for the time being. In my case, I was creating a bootable USB for Windows 11, and only had access to Macs and admin-blocked PCs.
Here are the steps that worked for me (no terminal required!):
Download the .iso file for the operating system of your choice from the Microsoft website.
Download UNetbootin at https://unetbootin.github.io. It’s safe and has been recommended here before, but as with any software on the internet, look it up yourself first just for the habit if anything.
Insert your USB flash drive.
Despite what you read elsewhere, you’ll want to reformat your USB from FAT32 to ExFAT. Search your Mac for “Disk Utility” and open it. Then select your flash drive and click “Erase” at the top. Enter a new name for the flash drive and use the dropdown to select “ExFAT”. Click OK.
Open the UNetbootin file and try to run it. If there is a security popup, click OK then go into your System Preferences -> Security and select “Open Anyway” next to UNetbootin.
Select the “Diskimage” radio button and search for the .iso file you downloaded in step 1. Also select the USB drive you are using. If concerned, you can find its name in the Disk Utility app, but mine was something like “Disk2s1”.
Click OK and wait. Could be several minutes loading certain files, so don’t worry - it’s still loading even if it’s not moving.
After it’s done, eject and use it to boot your new PC.
Hope this helps anyone else in my situation at least for a while.
