It always Bootcamp asistent 4 doesn't recognize Windows 7 Home Premium install disc

Question

Hi there,
I've search half a day for answers in already existing threads but haven't found a solution, so now I dare ask this question.
I have a Imac Mac OSX 10.7.5
Processor 2,7 Ghz Intel Core i5
Memory RAM 4GB 1333 MHs DDR3
I want to install with Bootcamp (version 4) Windows 7 Home Premium but after have tried numerous times Boot camp says that it cannot find the installation disc. I downloaded an ISO version of Windows 7 Home Premium 64bit from the website http://best-windows.vlaurie.com/boot-disks.html#full
and burned it on DVD-RW 4.7GB (TX). I also tried various other versions which I burned but with the same result. I wonder it's the type of DVD I use or the versions. Bootcamp doesn't accept burned installation discs?
If somebody can help me I would be thankful
greetings
Guy

Unfortunately, you can't buy just a key. Well, large organizations can get site license codes, or multiple individual codes so they aren't buying hundreds of boxes of media when you only need one, or a few for distribution. If you were able to get a working disk put together from the download, you'll only be able to get a short way into the installer, and then you'll be stuck.
The only other way to legitimately purchase a key is if you already own a legal copy of the OS, and just want another key so you can install Windows on another computer without buying another box. For that, you contact Microsoft where they can verify the key you already have (you read it to them, of course), and they will then sell you another key.
The sure way to have it work of course is to buy a copy of Win 7. It has to be a full retail copy, not an upgrade box. There is a way to use an upgrade disk, but you also must have a legitimate previous version the Win 7 installer can see. Meaning, you need two DVD drives. I did find a few sites selling just activation keys, but they were of course all illegal as the sites had nothing to do with Microsoft.
1) When looking for Win 7, be very careful on eBay. Purchase only an unopened box. Otherwise, chances are high the key has already been used by someone else.
2) There are system builder versions, such as you see listed here. Those are OEM disks that were supposed to be bundled with the sale of a particular PC model. Microsoft themselves say you can purchase these OEM disks and use them, but they are a one time installation. Once the key has been used, it is tied to that specific hardware. So if you were to get a new Mac and wanted to install Win 7 again, you wouldn't be able to from that disk. You can find these all over the place ranging from $85 to $95.
Be forewarned that full retail (non system builder OEM copies) of Win 7 have gotten very pricey.
