If you visit the manufacturers website and search for the "Support" pages for your specific model, you may be able to download some software to help with this task.
Update:
"Smart restore" is a Packard Bell program. If you have a Packard Bell computer you can run Smart Restore from Start
> All Programs
> Packard Bell Support
> SmartRestore
. I believe that it can also be invoked by pressing F11 soon after the computer is turned on. It seems likely that "Smart Restore" depends on software installed in a special system-recovery partition of the hard disk.
Apparently, one of the things you can do is create a recovery CD or DVD. You should do this when you first get the computer, before you have problems.
When you run smart restore, it may be possible to overwrite the system-recovery partition on the hard disk. Perhaps this is what has happened. If you do this, further restores are probably only possible if you have previously created a recovery CD or DVD.
I have read that you can purchase from Packard Bell a recovery DVD for a specific Packard Bell model, I would start at the support section of their website.
From a Packard Bell manual:
• Use the Packard Bell Recovery option in Smart Restore:
a. Click on ‘Start’ > All Programs > Packard Bell - Security & Support.
b. Select Packard Bell Recovery, then click on the Packard Bell Recovery button.
c. Your computer will restart and enter the Recovery Program.
• Use the F11 key when your computer starts:
a. Start (or restart) your computer.
b. Press the F11 key when the Packard Bell logo appears.
• Start your computer using Recovery or Master DVDs:
a. Turn ON your computer.
b. Insert Recovery DVD 1 (or Master DVD1) into the drive and close the tray.
c. Restart your computer.
d. Press any key on the keyboard when asked to boot from the DVD.
e. The drive's busy light should blink to show that your computer is booting from the disc.
Note: If your computer does not boot from the disc, restart your computer, press the F8 key when the Packard Bell logo appears and select the optical drive from the list.
• Start your computer using an external drive:
a. Connect the external drive that contains the recovery data to your computer.
b. Start or restart your computer and press the F8 key when the Packard Bell logo appears.
c. Use the arrow keys to select the external device from the list and press the Enter key.
d. The drive's busy light should blink to show that your computer is booting from the drive.
If none of these options start the recovery process, or are not available (for example, you have not created Recovery DVDs and the recovery data is no longer on the hard disk drive), you may request Recovery DVDs from the Packard Bell Call Centre (a fee may be charged)
