Hi I added a second monitor to my U300 and had flickering issues. Was instructed to go into Safe Mode and delete graphics drivers. Unfortunately when I set up the computer I set up an admin password that I can't remember. Soon after setting up I transitioned to using my Microsoft password. Without my admin password I'm unable to log in or perform any troubleshooting of my windows installation. Including resetting back to original. BTW, I'm stuck in boot to Safe Mode without network drivers. In an attempt to reset password by booting to usb utility or even reinstalling windows the bios will not allow me to boot to anything else but the hard drive. I've disabled all other boot options. The system just keeps returning to bios settings. Help!
