So yesterday I decided to upgrade my laptop to Windows 10 finally. It had been running a little slow so I thought maybe updating would help for some reason. It's been in the process of upgraded for probably about 18 hours now and its still on a black screen with the little windows 10 white loading circle dot thing and it seems to have made no progress. I'm just asking what I should do about this? I don't know what would happen if I shut it off so I haven't. Thanks for the help!
