It is only a few clicks away to complete the task. It is much easier to create Windows 10 bootable from macOS by using well-crafted GUI apps. The Simple Way to Create a Windows 10 Bootable USB on Mac Another way is to download a small size of Windows 10 ISO and burn it to USB directly on Mac, which is much simpler than using Terminal command. This can be only achieved in Terminal with text commands. The first way is to split install.wim file into small pieces and copy them to USB. Simply put, you can only make a bootable Windows USB on Mac with USB formatted to FAT32.Ĭurrently, there are two workaround to fix this issue. That’s the problem! And a lot of users don’t know those details and wasted hours without any success. Apple’s macOS does not support NTFS natively so it is impossible to burn ISO to a NTFS-formatted USB on Mac. How about NTFS? NTFS is a patent-protected file system owned by Microsoft.

And FAT32 is the only working option for creating Windows bootable USB drive.

Mount the ESXi Installation ISO and copy all the contents from the ISO to the USB flash drive.This means you cannot directly burn this ISO to USB because FAT32 file system is only capable of storing a single file less than 4GB. Flag the first partition on the volume as active and bootable.Start the command line partitoner fdisk in interactive mode (You will need administrative privileges for this). Don’t forget to use the disk# number obtained in step 2.

Unmount the USB Drive, Note: This is not the same as Eject. diskutil eraseDisk MS-DOS 'ESXI' MBR disk#

Now we need to format the drive with filesystem FAT32 and partition map MBR using the following command. You should now see another disk show up, in my case disk3. Insert the USB Flash then run the diskutil list command again. Open Terminal and list the mounted disks using the diskutil list command.

Download the ESXi Installation ISO (I used ESXi 7.0b).
