Kernel not showing in grub2

I compiled a 3.0.0-rc7 kernel. Everything went smoothly except it doesn't show in the grub menu even after doing sudo update-grub. I see the kernel in /boot/grub/grub.cfg. Everything appears right with the UUID's and all. I noticed in /boot it doesn't list the abi-3.0-rc7. System-map initrd-img, vmlinux and config are all there.

Would the missing abi- keep grub from recognizing it or am I barking up the wrong tree. If it is, how do I go about creating the abi short of recompiling.

Thanks, Scott

Check the /lib/modules directory for corresponding entry for 3.0.0. sudo update-grub does only scanning of /boot directory and puts them in a list so its look like grub update error.
abi-3.0-rc7 will not create because its only present when your kernel comes from standard distro.
Anyway you can manually edit grub.cfg file.

I'm using Ubuntu and looking in my boot directory the only abi-* files are those of the 3 distro-native kernels (in fact I only noticed they existed when I read your email.) None of my own kernels have them (or had them even before I upgraded to Ubuntu 11.04 as I recall). And all the kernels (about 20-30) are installed and booting OK. So maybe it's not that.

There are a couple of things you could check though:

- You're not naming your kernel something odd. You can build the kernel fine of course and do a make modules_install, but when I've misnamed a kernel (I've accidentally used underscores instead of hyphens before) update-grub (which is run automatically on make install on Ubuntu 11.04) complains and refuses to install it.

- Your /boot isn't full. Mine maxes out at about 50 kernels with their associated files. Again, the new kernel will not be installed if it's full :-)

Assuming it's not either of those I can't immediately think of what the problem is. Sorry - this is probably not especially helpful.

You can install something called "grub customizer" (just google for it)

I have grub-customizer already. It shows in the menu in that, too. I even manually added it to grub.cfg. I'm beginning to think something is wrong with grub in general. I think I'll reinstall grub and see what happens.

Thanks,Scott
