Check and see if unetbootin these days writes the correct disk label on
usb.
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, and took me reverse engineering their boot process to even figure
that much out. Far quicker to burn an infernal cd-rom...
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.
