Imao sam isti problem nakon što mi seuvalio nekav virus... dvostruki klik nije otvarao ni jednu particiju... ovako sam to riješio:
"Open your flash drive via Command Prompt (do this via Start->Run->cmd.exe).
Change your logged drive to your USB flash drive (e.g. if your flash drive is at drive E: then type E: on the command prompt then press enter)
Type ATTRIB -H -R -S AUTORUN.INF then press enter "
i onda restart i radi...
