How to Burn a Windows Bootable ISO Image on a Mac

By Hollan Johnson

Disk Utility is a program on the Mac that not only checks and repairs the permissions of your disks but can also create and burn an ISO of any disk you place in your Mac. Disk Utility will read the disk as a drive and create a burnable ISO out of it that can be used in a PC. This is very handy if you need to create a boot disk for a PC but do not have the ability to do so with the PC you have at the moment.

Things You'll Need

  • Windows install CD or DVD
  • Blank CD-R or DVD-R

Step 1

Insert the Windows install CD or DVD into your Mac computer.

Step 2

Open “Disk Utility” from the Applications/Utilities folder or from the Utilities folder in the Finder’s “Go” menu.

Step 3

Select “New Image” from the top of the window and click on the Windows install CD or DVD. Select a size for the disk image, making sure it is as large as the information on the disk. Select “None” from the “Encryption” menu and “Read and Write” disk image from the “Format” menu. Click “Create.”

Step 4

Remove the Windows install CD or DVD from your Mac by pressing the “Eject” button in the upper right-hand corner of your keyboard. Insert a blank CD-R or DVD-R into your Mac’s optical drive.

Step 5

Click on the Windows disk image and click on the “Burn” icon in the upper left-hand corner. Select “1x” as the speed and click “Burn.” Press the “Eject” key to eject the Windows ISO disk after the burn is completed.
