Symantec Ghost v11 has corrupted all the data and partition!!!!!!

Hi!

   I have tried to install the XP_3.gho from a bootable disk on my laptop which has 160GB harddisk whereas the ghost has been created from a 80GB hard disk.

  I don't know what happened wrong it has deleted all my partitions and data & now harddisk shows one partition combined the size of hard disk. I want to get my

  data back and in same position as it was before. Kindly help if some one have faced the same sitution and have a good solution to this problem.

Thanks.
