was given an older Toshiba Satellite C50-A-157 laptop by a lady who wants to give it to her great granddaughter for school work. Tried twice to install windows 10 and installation fails. Just doing an upgrade using this option from microsoft site "create windows 10 installation media, download, then run it" . I wanted to make sure it installed and activated okay, before I purchase a SSD and do a clean install. Any help would be much appreciated.
