If it is, when you type 'root >> (hdX,0)' it should report that a file system was found. The 'setup >> (hdX)' will tell grub to write the MBR to the specified disk. > THANK YOU! I could have used that once or twice, and had no idea that grub > could create a std. MBR. When I set up a RAID 1, I do it like this: device (hd0) /dev/sda root (hd0,0) setup (hd0) device (hd0) /dev/sdb root (hd0,0) setup (hd0) device (hd0) /dev/sdc root (hd0,0) setup (hd0) This way, all the drives are set up as if they are hd0. This way, any of them will boot normally as a stand-alone drive. -- Bowie
