Attempting to use the Boot Camp Assistant on my new iMac 27 (late 2012) with a regular 1TB HDD.   I had boot camp create a install disk on a USB flash drive from an existing Windows 7 Pro 64-bit ISO... it's the same ISO I used to install 64-bit Win7 on a PC earlier.


After selecting/dividing partitions and clicking Install, I immediately get the error "Need 64-bit Windows installation USB drive or DVD".  Searched the discussion forums but kept reading about people using 32-bit ISO's, which isn't the problem.    Why isn't the 64-bit installer not being recognized as such?

iMac, OS X Mountain Lion (10.8.2), Windows 7 Pro 64-bit
