Hello, I upgraded my 4th computer that was pretty old to Windows 10 today. It booted in fine after install, but it looked as if I was in a sort of safe mode, as mu graphics display driver was apparently not good. Windows told me it was going to install another graphics driver, so I let it do so and reboot, and it has sat at a black screen with no mouse for quite some time. I tried plugging it in to to my TV though HDMI, no luck, tried entering a password after hitting another key, and I tried installing a usb wireless keyboard/mouse combo (the computer dinged which indicated it knew I inserted a usb device), to see if maybe I could get a mouse cursor, and have had no luck. I have two graphics cards, an intel and an AMD so I'm thinking something went haywire there, but I can't figure out how to get into safe mode with Win10, everything I see shows you how to do it from within windows, not when you can't see the screen. Can anyone help?
Also, I am worried about reinstalling past the deadline. If it booted into Windows 10 and I had the OS operational when it said it was going to intall the driver, I'm ok if I have to restore to windows 7 and then reinstall later, right?
