Greetings: I'm upgrading a fileserver running 3.4 (upgrade to a larger disk). I backed up the data from the "old" disk and slapped in a newer, larger disk and installed Centos-3.4. No problems. Now, there are some files on the "old" disk that I forgot to move to the back-up disk, so I'd like to mount the "old" disk as /dev/hdd and reboot the system and transfer the files [hdd (old disk) --> hda (new disk)]. However, the old disk still has Grub on the MBR and when I boot, the system tries to mount the "/boot" and "/" partitions from BOTH disks! I get errors about duplicate partitions and that those dups won't get mounted.The fileserver does boot but with a configuration combination of both systems. Question: Grub is correctly installed and configured on hda. How do I get the boot process to ignore the old disk (and MBR) on hdd??? I tried google but I can't seem to find this fix. Thanks, Michael Chinn
