I have an older Dell Inspiron whose CD drive does not work, and whose bios dose not allow booting from a usb device. So, I downloaded the ADRIANE iso to the hard drive (it currently runs xubuntu) and configured grub with this boot entry:

menuentry knoppix {
loopback loop (hd0,1)/home/ADRIANE....iso
linux (loop)/boot/isolinux/linux debug nousb bootfrom=/dev/sda1/home/ADRIANE....iso expert knoppix
initrd (loop)/boot/isolinux/minirt.gz
}
When I boot the computer, Knoppix appears to boot ok --it displays a message that it finds knoppix 6 at /dev/sda1/home/.... It displays a messages that kernel 2.6.39.3 is loaded. Then it displays a message:

sh: can't access tty; job control turned off

It then displays a prompt. The hard disk is mounted at /mnt-iso. I cannot run any programs on the hard disk such as firefox. Even if I type the full path, a message is displayed that the program is not found. A character interface is displayed -- no graphical windows manager. Obviously somethins is wrong. Any ideas?

Thanks much!
