If I understand you correctly, you restored a partition using Acronis True Image from a previously made image file and afterwards lilo stopped working.
That frequently happens when using imaging software like acronis or partimage when you have lilo as the bootloader. To get lilo working again, you need to reinstall lilo using a livecd like slax:
Boot from the slax cd and login as root. Determine the mountpoint for the partition that your linux installation is on, say for example you installed linux on sda1 and the mountpoint in slax for sda1 is /mnt/sda1. Then open a console and run:
# chroot /mnt/sda1
# lilo -v
When you run lilo -v, you should see the output that indicates lilo was successfully rewritten to the mbr.
Reboot without the slax livecd and see if that fixes your lilo problem.
