Windows 7 Ult Boot Camp trouble

[Wateroksnmud]

I have the .iso file for windows 7 ultimate x64 on my Desktop of a Macbook pro 5,5. I clicked the .iso and selected burn to disc on a DVD+R. After the disc finished, started Bootcamp Assistant and alotted 5gb's to Bootcamp. After partitioning 5gb's, clicked start installation. When my mac tries to start the installation, it says there's no readable disc. Am I missing something?

5gb!? 😱 I'm sure the system requirements say at least 20gb for x64 win7

Did you verify the disc after burning?

No, it just said "validating" after it burned. How would I go about Validating it? I can move it to 20.... 😀
