Added second hard drive and system will tivo will not boot

Hi,

I added a second hard drive to my Tivo using the setup CD option and now the Tivo will not complete the boot it enters into a reboot loop. The Tivo reboots when the Oz Tivo 1.6 screen is displayed.

Any thoughts what might have happened and how I can fix this?

The Tivo was working fine before I added the second hard drive
