I am attempting to repair my friend's Samsung laptop running windows 8.1. I don't have the model name in front of me but I can post it when I get home if important. After a software update (as was told to me) and then subsequent reboot, the little cyclone spins around for a few seconds and then just a blank, white screen, no BSOD or something similar . I downloaded the manual which says in case of windows not starting to hit F4 upon start up. Hitting F4 does not cause any different change of events, just the spinning cyclone and then white screen. I can hit F2 to get into the BIOS but I don't see any settings in there such as "access recovery mode" or something similar that can help me. Unfortunately there is no cd/dvd media with the laptop.
Any suggestions? Are there any bootable troubleshooting programs I can download and burn to a CD that might help me? I was tempted to pay $120 for windows 10 and just see if it would boot off that and then load windows 10 but I'm afraid if it's not a software issue then I would be out $120.
