Knoppix boot from different partitions

[kl522]

Technically interesting but it's academic. I don't see any reason why you should install it that way - except just to challenge your ownself. What's the difference if you install the usual way by copying the KNOPPIX directory ?

Thanks for your answer. The reason is not acadamic, but simply I don't manage to make it working.

maybe it is because of the complex environment (Gujin on MBR and additional chained bootloaders) or my pc bios which does not show the USB disk mapping.

I do manage to boot KNOPPIX if it is on the local disk by adding this entry to 40_custom

menuentry "KNOPPIX LXDE" {
set root=(hd0,2)
linux /KNOPPIX/linux boot=/dev/sda2/KNOPPIX/KNOPPIX ramdisk_size=100000 lang=it vt.default_utf8=0 nohome apm=power-off vga=normal norandr xmodule=vga nomce loglevel=1 tz=Europe/Rome
initrd /KNOPPIX/minirt.gz
}

but on the USB disk it does not work.

<span style="background-color: #99FF99;">Thanks kl522,

that's not academic as I cannot boot KNOPPIX on my USB driver with the described tecnique. I wish I could.
Actually I can succeed copying KNOPPIX, linux and minirt.gz on a NTFS partition of my INTERNAL DISK the three files are fired with this 40_custom grub2 entry:

menuentry "KNOPPIX LXDE" {
set root=(hd0,2)
linux /KNOPPIX/linux boot=/dev/sda2/KNOPPIX/KNOPPIX ramdisk_size=100000 lang=it vt.default_utf8=0 nohome apm=power-off vga=normal norandr xmodule=vga nomce loglevel=1 tz=Europe/Rome
initrd /KNOPPIX/minirt.gz
}

no success on USB drive instead.</span>

kl522, I followed your criticism and I moved the same working configuration from the internal HDD to the USB drive to the NTFS partition (the former was ext2) and I can boot KNOPPIX finally.

If I add the cheatcode desktop=kde I get the following error: "Call to lnusertemp failed (temporary directories full ?) Check your installation"

can you suggest a working set of cheatcodes for kde ? gnome and lxde work fine.

thanks again
