Bootcamp, Device drivers not found
Hi.
I am trying to install Windows 7 using Bootcamp. I have put the Windows 7 iso file onto a memory stick using the bootcamp assistant. I have also done the other 2 checkpoints on bootcamp assistant. When I boot up the Windows install, I get to the point where I click "install now" but then a screen appears that says that a CD/DVD device driver is missing and that no device drivers were found. I can not procede from this screen. I have tried having the .iso file on one stick and the support softwre on another, both on the same, ive tried various memory sticks (usb 3.0 and 2.0) and nothing works. At one point I managed to get past this screen seemingly randomly when I used 2 USB sticks. However then I got a message saying that Windows cant be installed on this partition as it is not NTFS partitioned. So I clicked Format and then it just gave me an error. I have been at this for 4 hours and have found no solution.
