So i decided to reinstall windows. I have Windows home premium 64, but when i donwloaded different versions of this windows (from torrent and official versions) it says that the type of OS installed on notebook differes from the one im trying to install. Dont know what to do.
Are you able to start the HDD recovery?
Power up the unit, press F8, then choose Repair my Computer and then choose Toshiba HDD recovery
If this is not possible, you can order a recover disk which you have forgotten to create using the preinstalled tool called Toshiba recover disk creator:
