I am using grub2 also, but on another distro, with multiple kernels/partitions. I don't have a lot of firsthand knowledge, because not having a lot of patience, I usu just drop to the grub cli.
However, IIRC there is a grub2 command called update-grub that scans all your boot sectors on all your devices. At least that's the way its _sposed_ to work - ymmv. :-/ On Jan 24, 2014 12:32 PM, "James" <wirel...@tampabay.rr.com> wrote: > Grub2 on gentoo, seems a bit confusing.
