recently ide hdd became hdb after coming back from vendor with new mobo. need to access /mnt/hdb2/boot to edit /grub/menu.lst to reflect new partition name. i used: sudo mount /mnt/hdb2/mnt & various permutations, e.g., .../boot/grub, &c., since was suggested, same with dev although grub resides at /mnt/hdb2/boot/.

what commands do i use to access ubuntu/linux with knoppix? i used ver 3.4, C'T Edition. did not suspect that grub could not read hard drive dynamically to boot to new & correct name. ide hdd is slaved to rom, only one ide connection.
it has been frustrating trying to mount the partition to edit grub/menu.lst. unable to boot into ubuntu othet than read only fcn of knoppix.
