About all that I can suggest is that you need to be running a version of grub very similar if not identical to the version on the hard drive. Obviously, you need to use either grub or grub2, depending on what is on the drive, but you need to be more precise than that. It is probably worth tracking down every boot medium you have and trying the official grub MBR installation (there are instructions everywhere) from them. I recently copied my Lenny installation to a new drive, and it took me half a day to get grub working on it. I failed completely to install it from the original Lenny. As far as I can see, that really should have worked, but it is possible that grub cannot be installed to sda1 and then boot when the drive is promoted to sda0. Lenny's grub is not recent, and I think in the end, it was Knoppix 3.9 which worked, or possibly an early Ubuntu Live. I know the versions of System Rescue and Super Grub that I have failed miserably, and recent versions of Knoppix have grub2. The Lenny netinstall disc apparently doesn't have grub available for use from the disc. I had assorted problems, but mostly grub could see the grub directory contents on the hard drive, but was unable to read the files, though the running operating system could. And this wasn't LVM or some exotic new filesystem, it was ext3 on bare metal. Possibly grub2 is better... -- Joe -- To UNSUBSCRIBE, email to debian-user-requ...@lists.debian.org with a subject of "unsubscribe". Trouble?
