Kernel update, system (Debian) doesn't boot anymore

Kernel was 2.4.18-bf2.4, excecuted

apt-get install grub
grub-install

apt-get install linux-image-2.6.18-6-686

So far so good. When I boot however, I get stuck in a grub command prompt. What i did there was

root (hd0,0)       result from "find /boot/grub/stage1"
setup hd0
kernel /vmlinuz-2.6.18-6-686 root=/dev/hda1         (i had 2 partitions / and /home they're on an IDE disk)

initrd /initrd.img-2.6.18-6-686

So far so good, no error messages, just confirmation messages.

Now when i boot, i get a message "waiting for root file system"...and after a few minutes i fall into the busybox shell. Nothing i do there seems to have any effect.

Booting into the old kernel also doesn't work because i've no initrd of it. Can i create this in the shell ? i suppose not? Why is the root file system not working, but the vmlinuz file in /boot can be found? /boot is not a seperate partition.

How can i boot into the old kernel?
what mistakes did i make in upgrading from 2.4 to 2.6?

Does anybody have any ideas?

Boot from the first installation CD, but instead of starting the installation type "linux rescue" to start the command prompt rescue mode.
Run chroot to set the / directory:
chroot /mnt/sysimage
See if you can install grub again:
/sbin/grub-install /dev/hda
This should have fixed the problem.

If not, boot again to "rescue mode". Execute "grub". Then install grub using this commands:
grub> device (hd0) /dev/hda1
grub> root (hd0,0)
grub> setup (hd0)
Should also work...

Here is a comprehensive guide for solving problems with grub:

Good luck,

Didn't solve the problem, but i think it was unsolvable, thankfully it was a test machine that was being phased out so no harm done. Just installed a new system from scratch, thanks for the link though :)
