I have a HP 110-014 desktop with Windows 8 on it. When I turn it on, I can see the mouse but the screen is black & it will go no further into the boot process. I see no desktop or icons. How in the world can I troubleshoot this? How can I try to boot into safe mode since with Windows 8 you have to boot into Windows first to reboot in safe mode? I have a Windows 8 installation disk...any help will be appreciated.
