I just can't find a straight answer to this question.
I'm going thru an ordeal trying to get Linux on to a new laptop. Network installs are ruled out by an issue with my network card, and Knoppix won't give access to the CD writer to make intallation disks. (And there's no floppy.)
I've read and re-read the Suse CD-less installation guide at http://en.opensuse.org/Installation_without_CD
and this seems to show how to boot an .iso directly from Grub. But everywhere else, the line is "that's impossible".
Anyone have a definitive answer on this?
