OK, I pointed initrd to (hd0,10)/KNOPPIX......iso, but I don't know how to= =20 mount /dev/sda11 as part of the booting process. This is how I specified it: title Knoppix ISO root (hd0,9) kernel /boot/isolinux/memdisk iso raw initrd (hd0,10)/KNOPPIX_V7.0.5DVD-2012-12-21-EN.iso Where (hd0,9) is my /boot partition and (hd0,10) is a large partition that= =20 contains various images. > > Trying to understand your grub entry - what is /boot/memdisk?

Yes, that's right: http://www.syslinux.org/wiki/index.php/MEMDISK Unfortunately, it can only boot some images it seems, or it can only boot t= hem=20 if they have been stored in /boot. I copied memdisk from the KNOPPIX DVD t= o=20 my /boot, grub finds it and runs it, but then it fails to load the Knoppix = ISO=20 with this error: MEMDISK: No ramdisk image specified! =2D-=20 Regards, Mick --nextPart2198366.VoZRxJaTGn Content-Type: application/pgp-signature; name=signature.asc Content-Description: This is a digitally signed message part. -----BEGIN PGP SIGNATURE----- Version: GnuPG v2.0.19 (GNU/Linux) iQEcBAABAgAGBQJRmiI6AAoJELAdA+zwE4YeDSIIAL6uma5hLNWslOY+vlCtIP4l 4XehKYcbHtgAfY/aOPz9uCkVb1yTU7rBHKKFC6OAKKnA8PZtEl3BKuB8kqPqGxOg PQPN3lDmebfz7EJneSovcKsyI+SJ3Qob3F3iPadWNGT9th971HAI9zFquxzipyap 7narRhDembO34zcdrAh3qRs5eJ4xZYuuu1qvIDQ6tbRNuivc0CRda9yXEPTUt40C glgwGn0GrRMYNIShdZrIazc+LH/JU6xCEEBSd15SZlAiKjkzIAuz6zdZuyGxD28S cz6/V1MIqiSfyYgU99ccGRbkqdmJpSgAiHnPl03nH/DdQvgrJiUiAd1zAoKccxI= =7laK -----END PGP SIGNATURE----- --nextPart2198366.VoZRxJaTGn--
