Upgrade from Etch to Lenny, server no longer reboots

Hi, I just upgraded my (remote) webserver to Lenny from Etch. and no real issue occurs except that I cannot reboot that server. (I can only start in a rescue mode) I recall that a MBR change performed and I am wondering if that could be the reason for this failure. Would someone know how I can revert this MBR change ? I had switched back to my previous linux kernel, still cannot reboot. I would appreciate your help. thanks

• Upgrading from Etch to Lenny involves an upgrade from GRUB to GRUB2. For this reason Debian has lots of alert dialogs during the installation to tell you that this upgrade is going to happen and to confirm your GRUB config file and how to complete the upgrade process. You must not have paid attention to these dialog messages during your upgrade. There should have been at a minimum 2 such dialog boxes requiring interaction given the changes that were about to take place.

• you are lucky if you can get rescue shell.

  i don't know what is your rescue shell, but i've managed to repair grub few times by booting from knoppix from a cd, chrooting to the actual unbootable disk and following steps as described for instance here.

• after a few hours research. It seems to be related to a known issue, lenny changes the network rules during the upgrade process solution : delete the file /etc/udev/rules.d/70-persistent-net.rules and reboot

  Hope that helps
