Upgrade Debian Etch to Lenny ,

A client of mine got a root server with 1and1, it's debian 4.0 etch and I'm trying to upgrade to 5.0, but when I upgrade, I end up with a xen kernel that won't boot.

The new boot after upgrade is


I listed the error I receive below

I still have two other older kernels I can boot into, could you be more specific on how to "install the available kernel image in debian repo"

I tried just about every method I could for installing a kernel online, not sure what you mean.
