Can't find drivers when upgrading from 32 bit to 64 bit  

Hey I'm trying to upgrade to windows 7 64 bit and during the process it says it can't find the drivers and thus I can not go any further. I really have no idea what to do and my hours of research has so far be fruitless. Any help would be greatly appreciated as I'm starting to become slightly frustrated
I'm hoping that these two pictures are able to help any questions people may have:

What specific drivers are you looking for? Is this a desktop, or a laptop?

I get a message saying "A required CD/DVD drive device driver is missing" It's for a desktop. Sorry for the limited information don't really know what to look for

Where does this message come from? Windows? Or a third party program?

Windows when I'm trying to install 64 bit from my disk. I choose my language click next and that is the message that comes up

Where did you get the Windows Disc from ? It is more than likely a bad Installer .. Read the Tutorial below it is from one of our Installation Experts .. If you need to burn an ISO it is included in the guide ..

It was from a download in the link provided in the guide

Did you follow all the steps in the Tutorial ? ... Have you Downloaded another ISO .. Have you tried using a USB stick ..

Followed all the steps including the partition and now my computer just has a BOOTMGR is missing error every time I turn it on. So now I can't get another ISO or move it onto a USB stick
