Comment 2 for bug 281851

I have experienced a similar issue.

Installed from 8.10 beta AMD64 desktop cd. I selected a fresh root fs, but selected an existing ext2 fs as /boot without format. (This partition used for /boot in 8.04)

After install, grub was configured with 8.04 kernels (2.6.24-X) with 8.10 fs as root

vmlinuz-2.6.27-4-generic was missing from /boot

Files that were copied to /boot -
initrd.img-2.6.27-4-generic
abi-2.6.27-4-generic
config-2.6.27-4-generic
System.map-2.6.27-4-generic
vmcoreinfo-2.6.27-4-generic
