There should be more than two CD's for Toshiba Recovery. Possibly two DVD"s, but it would be more like 5 or more CD's if that's what you're using.
Did you burn the disks from the Toshiba Recovery disk creating program? Did you complete all of the steps supplying all the disks it required?
If so then it should prompt when to change from one disk to another. Are you getting this prompt?
If this fails you can try running Toshiba Recovery from its partition on the HD, using one of the methods given here:
Toshiba HDD Recovery Utility
If this fails then you can
