My tosh iba laptop was my reading my sd card so I went online and checked for solutions, and it told me to go to device manager and etc and uninstall whichever had the yellow exclamation points, and to restart, but then, my laptop won't restart. It is just looping from black, to the bios page that has the tosh iba leading innovations thing, and I don't know what to do, and I'm worried it won't go back to normal, what can I do?
