As many people pointed out, it's not a grub problem, it's an ext3 LABEL problem. It's only useful if you make sure that you label all of your partitions with unique names. My guess is that when Linux surveys partitions to find a label/partition mapping, it surveys all the partitions, and in the case of duplicates, it's the last one found that makes the mapping. (any other guesses?) ------------- There are essentially two ways around the problem: One is to use the method that you did (use hard partition names). The other is to ensure that your partition gets a unique name when you create it (but you'll still end up messed up if you do disk cloning like you did). If you're doing an ad-hock forensic mount where you have partition label clashes,you can always break into grub and edit the boot line to specify the proper boot partition. If you're also mounting LABELed /usr, /var, /home, etc. directories, then you'll probably have to do a rescue boot from CD and edit /etc/fstab and grub.conf before you boot the system with the spare disk. (If you look in /etc/fstab, you'll see LABEL= entries for root and any other labeled FS that you created with the system.) I belive that this problem can also occur for LILO boots under recent kernels.
