Making a Windows Bootable USB from a Mac

I have an old Windows corporate machine that won't start or complete a repair to its hosed Windows installation. I want to rebuild it with Windows 10, but I can't find a way to effectively create a bootable USB from my Mac since the ability to do so within Bootcamp was removed with Mojave OS.

Most of the online instructions involve buying some form of suspicious software to do this, but I did find one website that walked me through the process of expanding the Win10 ISO file into its own drive on the Mac, and then copying the contents of that drive to the USB - I tried this, but the result was the Dell machine would not boot no matter what I tried with the BIOS.

Are there any reliable, free utilities out there that would take an ISO file and burn it to a USB stick as bootable media in the BIOS (not UEFI)?

I would have recommended Rufus except I saw you were using a Mac. A friend of mine suggested unetbootin. https://unetbootin.github.io/ otherwise I would suggest finding a window box and use the media creation tool if at all possible (highest success rate) or Rufus with an iso file (80% success rate for me... Usually just "reburn" it a second time fixes the issue.)

Microsoft own tool can create a bootable Windows 10 USB flash drive. But I don't know if this works with Mac or not.

Maybe you should ask someone to create that for you. It only takes not more than 15 minutes.

You can do it from Bootcamp Assistant in the MacOS Utilities.

Are you talking about Windows Media Create tool?I have never used this tool on Mac,but i don't think it will work on Mac.To make Windows bootable USB on Mac,why not use Mac Disk Utility?Such a professional and powerful tool.

I ended up taking the old laptop to a local repair shop and paying them $50 to strip the hard drive clean and put a fresh copy of Windows 10 on it - was worth dropping the entire hassle.

Thanks for the update. But still curious to know if it'd still work (in case anyone else encounters this). Might be worth it for me to pick up a "current" macOS system just to try it...

Glad it got resolved.
