Kernel not showing in grub2

Kernel not showing in grub2

[scott]

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

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

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.

Cheers
Julie

No naming convention problems. /boot is not full either. I'm stumped on 
this one.

Thanks for the reply anyway, Scott

PS: Sorry for the post to your private email, Pritam. I hit the 'reply' 
button instead of 'reply-to-list'.

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

Evidently is was something in grub. I reinstalled it and everything 
works as it should.

Thanks for all the help,
Scott
