   Have you modify your "HOOKS" in your /etc/mkinitcpio.conf as you said in your previous posts? Do not modify it unless you _really_ know what your doing.

   Also, are you sure your grub config is valid and correct? you should at least know how path and references works, and it should not trying to load an invalid file and block device.

   Could you post your /boot/grub/grub.cfg as well as your modifications in /etc/rc.conf and /etc/mkinitcpio.conf?

   Also, could you post your partition numbers and hard drives and where Debian and Kahel OS is installed and what partition your grub MBR is installed?

   /boot/grub/grub.cfg :
   ###BEGIN /etc/grub.d/30_os-prober ###
   menuentry 'Arch(on /dev/hda3)' {
   set root=(hd0,3)
   linux /boot/vmlinuz26 root=/dev/hda3
   }

   grub2 shows me debian and arch then enter to arch then ==> black screen ==> error: unknown filesystem press any key to continue...

   where hda1-> debian
   hda2 -> swap
   hda3 -> kahel[btrfs]
   hda4 -> /home

   is that really safe? debian and kahel uses one /home ?
   swap would be fine, but /home is used by debian and kahel

   hm...shouldnt be much of a problem ....
   well..theoretically..since home is just a place where you keep your files...
   though your home might be excessively big interms of size ...

   Im not sure if the current status page of Grub2 is up to date, but according to it BTRFS and NILFS is not a supported filesystem. So if its not supported yet, you will atleast need a /boot partition with a supported filesystem. Maybe even the root filesystem has to be a supported one, I dont know.

   I asked at their IRC channel for clarification: http://grub.enbug.org/IrcChannels

   <Fenrin> Hello, im just wondering if BTRFS is supported by grub2 or not yet? I know its not in the current status list...
   <Fenrin> maybe anyone can help?
   <fezie> no it's not
   <Fenrin> ok
   <Fenrin> does this mean that only boot has to be a supported filesystem or root too?
   <Fenrin> thanks
   <fezie> grub-mkconfig doestn't work even if just / and not /boot is btrfs
   <Fenrin> ok thanks
   <fezie> but except of that it doestn't matter if /boot is some supported fs and / btrfs
   <Fenrin> ok good to know

    I don't see any benefits of using Grub2 over Grub, only headaches, IMHO.

    Grub2 can't boot those filesystems while Grub1 can perfectly do it without any complications.
    Grub2 does not properly detect a separate /boot partition properly and won't install on them properly.
    Grub2 add things that doesn't really matter because you only need to boot your system, nothing more... Do you really need to play Tetris on your MBR bootloader?

    I don't really see the point of switching to grub2.

    I guess you would have to reinstall KahelOS with a seperate boot partition.
    Ext2 is a safe choice for the boot partition with >=256MB size. At the installation of KahelOS you could install your grub on the /boot partition (dont install it to hda, if you want to keep grub2 of Debian).

    so, if you would use following partition setup...
    hda1-> debian
    hda2 -> swap
    hda3 -> /boot [ext2]
    hda4 -> kahel[btrfs]
    hda5 -> /home

    both of the following entries should work to boot KahelOS:
    menuentry 'Arch(on /dev/hda4)' {
    set root=(hd0,3)
    linux /boot/vmlinuz26 root=/dev/hda4
    }

    menuentry "KahelOS" {
    set root=(hd0,3)
    chainloader +1
    }

    The second menu entry would open the grub of your KahelOS. Im really not sure about this solution. You can also use grub legacy like joelbryan suggested. I dont use Grub2 either.
