Hey guys, someone approached me today with a problem, he just got a new hp desktop pc with win10 but had a guy install a dual boot system with Ubuntu. Now whenever he tried to log in he is seeing a lot of "scribbings" and wants to know what he can do to correct this situation. I have never installed any linux system, I only use knoppix, Puppy Linux and Parted magic to do data recovery or formatting e.t.c.
He wants to drop off the pc here for me on Wednesday but since he uses that pc for his work I willonly have one day at the most to correct this problem. What can you guys advise me to do here please?
