Can you debug this? I've checked this again. If I do this booting from my pc I get the grub2 floppy booting again. If I do this from qemu the FATAL: INT18: BOOT FAILURE appears again. I would bet that it is a qemu bios's lack of the 18 interruption. >> 20) grub rescue help >> ======================== >> >> help : Types the commands and a minimal explanation: OK >> help any_command : Types the commands and a minimal explanation: NOT OK >> help not_a_command : Types the commands and a minimal explanation: NOT OK > > huh?

This comes from GPL 2: If the program is interactive, make it output a short notice like this when it starts in an interactive mode: Gnomovision version 69, Copyright (C) year name of author Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'.

I only wanted to make you know that the "root" variable was actually a read only variable because there is no way to delete (unset) it. It always comes to live again. Is it a normal thing? adrian15
