Hello
Today I installed GRUB 2 and I configure it
But when I try to boot my system I got only Grub console , when I type manually settting form command line where kernel,initrd my systems boot to fallback and he says that he can't find '' device.
I got my system on /dev/sda1.
That's my working seetings from GRUB:

  1 # Config file for GRUB - The GNU GRand Unified Bootloader
  2 # /boot/grub/menu.lst

 41 kernel /boot/vmlinuz26 root=/dev/sda1 ro rootflags=data=writeback
 42 initrd /boot/kernel26.img

And that's my setting from grub2:

  1 # Config file for GRUB2 - The GNU GRand Unified Bootloader
  2 # /boot/grub/grub.cfg
  3 
  4 # DEVICE NAME CONVERSIONS
  5 #
  6 #  Linux           Grub
  7 # -------------------------
  8 #  /dev/fd0        (fd0)
  9 #  /dev/sda        (hd0)
 10 #  /dev/sdb2       (hd1,2)
 11 #  /dev/sda3       (hd0,3)
 12 #
 13 
 14 # Timeout for menu
 15 set timeout=0
 16 
 17 # Set default boot entry as Entry 0
 18 set default=0
 19 
 20 # (0) Archlinux
 21 menuentry "Archlinux" {
 22 set root=(hd0,0)
 23 linux /boot/vmlinuz26 root=/dev/sda1 ro rootflags=data=writeback
 24 initrd /boot/kernel26.img
 25 }

I tried this config:

  1 # Config file for GRUB2 - The GNU GRand Unified Bootloader
  2 # /boot/grub/grub.cfg
  3 
  4 # DEVICE NAME CONVERSIONS
  5 #
  6 #  Linux           Grub
  7 # -------------------------
  8 #  /dev/fd0        (fd0)
  9 #  /dev/sda        (hd0)
 10 #  /dev/sdb2       (hd1,2)
 11 #  /dev/sda3       (hd0,3)
 12 #
 13 
 14 # Timeout for menu
 15 set timeout=0
 16 
 17 # Set default boot entry as Entry 0
 18 set default=0
 19 
 20 # (0) Archlinux
 21 menuentry "Archlinux" {
 22 set root=(hd0,1)
 23 linux /boot/vmlinuz26 root=/dev/sda1 ro rootflags=data=writeback
 24 initrd /boot/kernel26.img
 25 }

But it doesen't work
But the problem is here that settings from GRUB2 doesen't works
They are the same I was trying set root=(hd0,0) but this doesen't work .
Thanks for any help

Ok problem solved I removed grub directory from and intall grub by:
grub-install
And I have GRUB2 working.
I have a question why we don't backup grub direcotry and make new?
We can do that in grub_install from tarballs of officail packages

Hello SpeedVin!

"I have a question why we don't backup grub direcotry and make new?

You did a backup, what's more ?

And after this install grub on mbr or boot partition
Command to install grub:
grub-install /device

Can't you only install grub2 if you have blank space at the start of the device or a partition with the bios_grub label (that can only be added from git parted)?
