Arch Linux

my wife's laptop is currently on windows xp.  had puppy linux and debian stretch on it and decided to go back to windows because i couldn't get unetbootin to work in linux since the internal dvd drive is having problems, and i wanted archlinux32 on it since i just installed it on my own pc. i downloaded the iso image and used unetbootin to load the iso and all was going fine until i got to "mounting '/dev/disk/by-label/' to /run/archiso/bootmnt"
it just throws "ipERROR:' /dev/disk/by-label/ device did not show up after 30 seconds. Falling back to interactive prompt.  please help!!!!!!!!!
