Manjaro XFCE's Boot Menu didn't show up when I boot into live media

According to the User Manual, there is supposed to be a graphical boot menu prompting you to select drivers etc when booting into live media.

But on my live usb, there is no such menu. Instead, a bunch of text showed up and I boot straight into the desktop.

Is that a sign of a broken media? The checksum matched.

Help.

what manual, where?
no linux does that for proprietary drivers.
