Install Windows 7 On Mac Using USB

I'm trying to install Windows 7 on my Mac using a Windows 7 DVD.

I downloaded the ISO from My Digital Life and burned the image to a DVD. I then created a partition using Boot Camp for Windows on Mac and started the installation by inserting the DVD. Later when the Mac restarted, the Windows 7 installation begun.

I was then asked for the CD/DVD drivers. I searched Google about this but couldn't find any proper solutions. People say that the CD/DVD drivers issue is due to the downloaded ISO being corrupt or the DVD not being burned properly, but this is not certain.

As a result I've now decided I don't want to use a DVD for the installation. Is there any method for installing Windows 7 on a Mac using the ISO image downloaded, perhaps using USB?
