I downloaded Alpha 2 and placed it on a USB key with unetbootin.

When I boot a Thinkpad x250 with Alpha 2 iso, it comes up with "Missing
parameter error". However, when I provide Install at the "Boot:" prompt,
it boots to the installer.

However, on a i386 desktop machine for which I would really like to
install devuan, booting the key comes up with "Missing parameter in
configuration file: Keyword: path". In this case, there is no Boot:
prompt.

I don't understand these messages or if they are compatible.
