So my Lenovo AiO was updating upon startup, when it was about 70% i decided to force shut down my pc because my friend keep asking me to accompany him to this stupid place. And when back home, after starting my pc and then passing the "Lenovo" screen, my pc just go black with the white underscore in it. I thought it was like cmd, so i can just like type "sfc/scannow" but no, its not. After doing a LOT research, most of them having this problem can just press F8 and go to safe mode, but mine not work. The only thing works is presing CTRL+ALT+DEL. Instead of opening those choices like switch user, signing out, etc, it restart my pc. I dont know what to do anymore. There's a ton of important data in my pc. Ffs I'm starting to lose my because of these potato. PLEASE HELP ME ASAP!
