how does network install figure out 64-bit from 32-bit?

But I don't see it as mounted in nautilus. Just that it is there. Indeed, I
make sure it is not mounted. 

You need to close the

I have done exactly the same thing. Just to clarify the following is the file I
am copying:

wget -c
http://mirror.anl.gov/pub/fedora/linux/releases/7/Fedora/x86_64/os/images/diskboot.img

And then I use the dd command:

dd if=/media/dvd/images/diskboot.img  of=/dev/sdb bs=512

but to no avail. Is it possible that I am making a mess somewhere? Is it that
bs has to be something else?

Note that I do potentially get a bootable USB since it says boot error, rather
than OS not found.

Can anyone please help?

Best wishes.
