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 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,

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'.
