So I have an old windows PC which has a new HD. I downloaded the windows 10 Iso from MS, now I am trying to find a way to burn the iso to a USB drive as bootable.

My old windows friend imgBurn is now riddled with malware, so I am avoiding this.

I have seen that the mac Disk Utility used to be able to do this, but with 14.4 at least this feature seems to have been removed. I tried the restore function, this failed with error 22.

Any ideas where I can get hold of a free, malware free tool which can burn an iso image to a USB stick for Mac?

thanks!
 
Would've thought Disk Utility could still do it, but I'd just use dd. It's built-in. It's a command line tool found on basically all Unix.

Works like this:
sudo dd if=[path to ISO] of=[BSD device ID for USB drive]

I'm presuming you just need a Windows 10 USB boot because your computer has malware issues - you're not doing Boot Camp or trying to install Windows 10 in a VM.

Try what casperes1996 suggested. See if that works.

If it doesn't, there's an article on the web that says what you need to do is:

1) Erase the USB flash drive using the Disk Utility app. Select "ExFat" as the format and "Master Boot Record" as the scheme. Let's say you name the flash drive as "MYUSB".

2) Double click on the Microsoft .iso file. Take a note in the Finder of what the iso file mounts as - for example, I have a Windows 10 .iso that mounts as "CCCOMA_X64FRE_EN-US_DV9"

3) Open the Terminal app and enter the following command
cp -rp /Volumes/CCCOMA_X64FRE_EN-US_DV9/* /Volumes/MYUSB

(Replace CCCOMA_X64FRE_EN-US_DV9 and MYUSB with the appropriate value as noted in #1 and #2. The operation will be done when the command prompt returns with your computer name plus the "~" symbol.)

This seems pretty simple - this web article says it works (it also says the Finder copy won't work that's why you need to use the Temrinal app).
 
I tried the method that I took off the Internet. I tried the resulting USB on my 2012 MBP - holding down the alt/option key at startup (if you're using a PC, they have their own way of doing this) and selecting "EFI Boot" as the boot disk and I get to the Windows Setup screen so I presume this method will work. I didn't think it would be that simple.
[doublepost=1558980419][/doublepost]Just realized - if you don't see the "Scheme" option in Disk Utility when erasing the USB, you need to press the Command-2 key combination and then select the part of your USB flash drive that is the left-most (not indented). Then if you erase this, the "Scheme" option will appear. If, after you do this, you want to go back to the streamlined look, press the Command-1 key combination.
