Yes grub is install properly and yes the boot partition was mounted when I copied the new kernel across and changed the grub.conf. What's really confusing me is there's no syntax error in the grub.conf that I can see, and the first kernel on the list boots fine. Anyone got any cluse as to why grub can't see the second kernel?

HTH Matt Hi, Another thing you can try is tab completion in the grub menu. Just hit the "e" key twice and let grub help you with what kernels it can see. Hope that helps.
