This appears to be a problem with the install-amd64-minimal-20160908.iso image's kernel. Looks like there's a bug in it that prevents it from recognizing or using USB drives. dmesg from the shell shows it can't even see USB drives when they're plugged in. Yes, I tried multiple drives, and said drives work fine with a vanilla kernel. No label problems, just "we didn't bother to test whether the USB storage system worked".
(I have run into enough weird bugs with Gentoo's supplied kernels that now I grab a vanilla tarball and build it as soon as I can. YMMV.)
I ran into an issue years ago fiddling with Arch where their iso would only boot with a particular disk label, using that (in theory) to find what /dev/sdX it was found by udev as. A flawed ass-u-me'ption, as unetbootin didn't bother to write the correct label the iso was looking for
This seems odd, because when you dd something to a raw device, you shouldn't even have to write a label--the label is already in the ISO (or whatever).
I've personally never had good luck making/booting linux iso's from usb oddly, especially debian-installer-based systems just never work right even once booted. I keep an old usb cdrom around as sadly we can't seem to move beyond them.
We will always have the old stuff with us, because the new fancy stuff so often overpromises and underdelivers in spectacular ways.
