Hello MD
Recovery disc creator and HDD recovery installation can work with original “factory settings” only and if you have made some modification like second OS installation or anything similar it will not work anymore.
Many people make this mistake and don’t follow Toshibas advice. What must/should be done is creation of recovery disc at first and best moment for this is after purchase.
When the recovery discs are created you can do with your notebook whatever you want and one day if you want to have “factory settings” again you can use your recovery discs for recovery image installation.
Sorry but now is too late and you cannot do anything about that. What you can do is to order original Toshiba recovery disc on
