Bootcamp and Windows 7 - Mounting the .iso onto a blank DVD-R So im trying to install Windows 7 Ultimate via Bootcamp on my Macbook Pro 13"....Managed to partition the HDD but for some reason whenever I click install, the Macbook restarts and I'm met with a black screen with white text that read something along the lines of "This is not a bootable device" or something like that. 

Now i should note that Windows is on a DVD-R, so i thought maybe the DVD-R was damaged so i created an .cdr image of the DVD-R via the disk utility and then changed the file name to .iso as stated on this website - http://www.ehow.com/how_2093946_create-disk-image-mac-osx.html. 

But now I'm wondering how do I mount the .iso onto another DVD-R? Or am i going about the entire thing completely wrong? In other words, help!
Are you burning the ISO file on to a DVD-R as a file or as a DVD image? There's a big difference between the two. Only the latter method works.

To burn a DVD from the ISO image, follow this Apple guide:
