I'm curious. If I put a debian iso on a flash drive can I put a second file on that flash drive with a boot parameter or two in it which the iso will find when booted and use? I'm asking this since I'm trying to help a friend remotely to rescue his hard drive and both of us at best have infrequent sighted assistance available. Alternatively if his system boots a flash drive (we haven't established that yet) would there be some way for him to know when to key in boot parameters without looking at the screen?
