RE: Recompile error

[Rod Rioux]

Im sorry.. yes it is a redhat system and I wanted to replace
the kernel with newer... I compiled the the modules in the kernel
and I have compiled the kernel with modules also.. I have created
initrd images for both .. still no luck.

fdisk -L:

You don't need to touch the labels.

Are you having a redhat system and you replaced the redhat kernel with
your own ?
And you did not make an initrd ?

More details would be helpful :
 - fdisk -l ( the partitions of all your hard drives )
 - cat /boot/grub/grub.conf ( your grub configuration )
