Nero Backup

Hello

I have ran nero back up on my laptop a about 4 months ago. It backed it up to about 7 CD-Rs. The other day I had to reformat due to someone messing around with the laptop.

After running the restore utilitiy one disk 1 and inserting all the disk I reboot. Then I get an error saying “a disl read error occured” press ctrl+alt+Del to restart. Also sometimes it says no OS found.

Has anyone encountered this?
