call them.
If you bought it from a reseller, call Toshiba and ask for the CD.
Some systems have a recovery partition on the HD. Access is machine dependant, you'll have to look around the Start menu.
I`m not very computer literate so I hope you can help me. I recently bought a Toshiba A20. I was expecting there to be a CD included in the box which takes my computer back to the beginning as if it`s never been used ( I don`t know what you call this process) as I had these CD`s with my old laptop- Toshiba A10. Have I been fleeced? If so, how can I get a hold of these CD`s or is there a way to do this without the CD`s.
Thanks in advance.
