The same problem when I try to use USB stick.

What to do, what's wrong?

You burned the ISO to the USB the wrong way.

If you have a non-retina MBP, you have to use a DVD disc. If you took out the optical drive, you're going to have to put it back.

I Put back DVD and no result. Maybe I burned the DVD in a wrong way. What I did was I opened ISO file, marked all files inside and right click and burn. Was it correct?

No you can't, because when BCA detects that you're on a Mac that came with an optical drive (regardless of whether you removed it or not), it'll only allow installation via the optical drive.

I see, so my primary hdd should be partitioned for both OS X and windows 7. then the secondary hdd is just for storage. my main OS will be windows for my engineering programs, and OS X will be on the side for graphic design stuff

OK, the problem was wrong mounted ISO on DVD - that's fixed. But now I have this warning:

Yes. On later models it is supported with both optical and USB installation. My mid-2012 classic MacBook Pro 13" supports both and I have used both.

I get this error with an official disk, what am I doing wrong? I am using a 3rd party generic DVD drive through USB on a 2014 iMac with no internal optical drive.

Yes. If you can get your hands on an ISO through either her or another source you can use that in the Boot Camp Assistant to create a USB installer.
So I would use the MS software to take the disk onto the USB, then bring it onto the I!ac and use Bootcamp? Cheers for the help btw

@MartinAppleGuy Yes. You would either create an ISO of the disk and then copy that to the Mac and use it for Boot Camp Assistant. When you insert the disk into the USB optical drive on the iMac, does it appear on the desktop?

It does after so long, but it appears the the read speeds of the drive are extreamly low, as playing a film with the drive would make it stutter every 2 seconds and freeze up for 5 minutes We're just going to get a new drive and that will hopefully work
