I installed Debian Squeeze 2.6 (on a recently bought server) with a software RAID1. During installation I installed GRUB loader (1.9 version). System boots OK with GRAB loader BUT right after authorization it cannot execute GRUB command (I want to copy the GRUB from the SDA to SDB). System warning right after GRUB command invocation looks as: root@servername:~# grub -bash: grub: command not found How it could be? (GRUB already installed and no any other OS was installed at all)
