I uninstalled an old virus protection software in order to install abother one. After i uninstalled it told me it needed to restart so I did. Now my HP laptop will only load till the date and time screen before you click to logon. The time still changes, but the touchpad wont work, i cant see a cursor and my laptop will not load in safemode. Nothing happens when i hold down shift on any of the F buttons, only F2 which took me to the BIOS screen but that did nothing either. I feel like i've tried everything and I dont know what to do?
