Well, digging around got me no-where...: # fdisk /dev/hdb Unable to open /dev/hdb I get the same for /dev/hda. And fdisk -l gives: # fdisk -l cannot open /proc/partitions When I tried the same on Knoppix I get: knoppix@1[knoppix]$ fdisk -l Can't open /dev/hda Can't open /dev/hdb So let's try e2label: # e2label /dev/hdb e2label: No such file or directory while trying to open /dev/hdb Couldn't find valid filesystem superblock Ok, what about parted? knoppix@1[knoppix]$ parted Error: No device found Retry/Cancel? Anyone have any ideas on what I should try now? Please help me get this straight... - I can't have two partitions with the label '/' (even though Ubuntu starts fine!) - I therefore should change one of the '/' labels to something else - what could that be? - After I've changed it I need to edit 'grub.conf' and '/etc/fstab'. Since it's tricky for me to even read those files just now, could you give me an example of which bit to edit? In 'grub.conf' I think it's something like root=Label='/' should change to root='/dev/hdb1 and something pretty similar in fstab. Am I getting the idea of this problem? Duncan
