Boot Camp Assistant needs to create a Windows 10 installer disk. To perform this task, you need a Windows 10 ISO image file to be available. The ISO file can be stored on your Mac's internal drives, or on an external drive. Creating a Windows installer from OS X is actually quite simple - Boot Camp Assistant can do it for you. If you’re on a newer machine without an optical drive, you probably have an option that says “Create a Windows 7 or later version install disk”. Click that and point it to your ISO image.

Hi All, I am trying to create a Windows 7 partition on my Macbook Pro (late 2009) running OSX Lion 10.7.2 with Boot Camp 4. Clicking on 'Install' button to create the partition and install Windows with the disc in the drive gives an 'The windows installer disc could not be found' error.

The disc is a downloaded Windows 7 installer disc image, unpacked so it looks exactly like a standard Windows install disc with all files (i.e not a single ISO or image file). Could the content of the disc be an issue, as to why the Mac cannot read the disc?

I have read in another support thread that the solution to this is to burn an Windows 7 ISO as an image (DMG?), so would keeping an ISO file on the disc work? Advertisement miguel.loff, Your instructions were so helpful! I was struggling with this for a few days. I tried multiple times to burn the.iso file onto the DVD and this was the only method that worked. Bootcamp Assistant replied with 'installer disc could not be found' for all other attempts. If you are downloading Windows 7 from the internet (from your school or something), then DEFINITELY USE THIS METHOD BECAUSE IT WORKS.

Heres exactly what I did to get Windows 7 running on my Mac: A. Download Windows 7 file; if file is an '.img' change it to an '.iso' B. Follow burning method from 'miguel.loff' YOU MUST USE A DVD not a CD 1) Insert blank CD 2) Open Disk Utility (Applications>Disk Utility) 3) From the File menu, choose Open Disk Image and select the.iso that you want to burn 4) In the list of volumes (at the left of the window), you will now see an item representing the.iso file.

5) Click on the burn button and you're done. Open Bootcamp Installer on your mac and follow instructions. Download Windows 7 support software to an external hard drive. THE EXTERNAL HARD DRIVE MUST BE FORMATTED TO MS-DOS(FAT) (idk what that means but its easy to do.) In order to preserve the mac portion of your external HD, create a Windows partition for you your external hard drive [MS-DOS(FAT) ] in the same disc utility used to burn the DVD D. Insert Windows 7 Disc; Partiton your computer's HD, and then Windows installion will begin.
