I have tried this flash install (in Knoppix 6.1 from LX Magazine) with a couple of USB sticks of different brands.
The Knopiix system seems to install OK. At least I get no error messages. No other guiding messages either, for that matter.
A preliminary (my level of understanding) inspection of the flash drive content seems to agree.
But. the computers I tried will not boot from thoose USB sticks. I have enabled boot from USB-sticks in the bioses,
and even tried disabling all other boot options. They simply complain they cannot find an OS.

Am I supposed to have done other things as well, like installing GRUB or Lilo in MBR (not a thing I look forward to). I have been under the impression that this is done by the Knoppix flash drive installer.

Please help with some hints.
