I have this file server with CentOS 4.0 Each time a new kernel comes out, i have to recompile it, becuse i need Appletalk support and the kernel doesn't have it.

I've done this before many times and in other servers, and all went well.

Now, in this particular server, with the new 2.6.9-11, after i've recompiled it, created the .img and edited grub, the machine doesn't start at all. It says it can't find the kernel image.

I would guess you somehow did a mistake editing /etc/grub.conf which is a symlink to /boot/grub/menu.lst.

I cannot even boot with older kernels.

To worsten things, i have LVM, so "linux rescue" tells me there's no Linux installation in the server and leaves me with a prompt.

The rescue mode is aware of LVM2 and can mount that.

Now, i can mount /boot because it is outside the LVM, but when i do it, i lost access to any command, even a mere ls.

Tried to pre-copy vi before the /boot mount and could access /boot/grub/menu.lst

Everything seems fine, the files are all in /boot ...!!!

Do i need to run grub command after editing menu.lst ?

No. This is one difference to lilo. It may be helpful if you show us your menu.lst / grub.conf.

Never did that. And why can't i boot from older kernels ?

I can only imagine that the menu.lst is broken somehow (strange characters in it).

Now, the really nasty thing: somehow, i don't have the smallest hint, i had a 500 GB external USB disk to make the backups, and the "linux rescue" erased it :( :( :(

What do you mean with "erased"? You plugged the drive in on a different host and the drive is completely empty?
