Q: Problems with formatting USB flash drive for boot camp. Help!
I formatted a 16 GB flash drive to Master Boost Record and it's only have one partition, and it's under the FAT32. It has 16.04 GB of free space and my Windows 7 ISO will take up 16.02 GB. Every time I drag it into the partition I made, it says the fine is too big. So i decided to use my 1TB external hard drive, and even though when I format it the same exact way, and it has 1 TB of space it still says it doesn't have enough free space. What gives?
iMac, OS X Yosemite (10.10.3), Model ID 11,2 (21.5" mid 2010)

Your iMac is iMac (21.5-inch, Mid 2010) - Technical Specifications, which has a known issue with AMD GPUs as noted in Boot Camp: iMac displays a black screen during installation of Windows 7 - Apple Support . The second link has a set of steps that you should follow.
The second link only mentions 2009/2010 iMacs, but the AMD GPU is common. I have seen this behavior on iMacs with AMD GPUs.
