I am using the windows 7 on mine Toshiba Portege M900 and I have upgraded mine operating system form windows 7 to windows XP. After upgrading to windows XP I wanted to restore all original factory setting on mine system. I have tried the factory setting by using the HDD Recovery Wizard but during this time I have got the error message and I am unable to create the default factory setting. Now I donít what to do. Can anyone suggest on this and so that I can solve mine issue.
