Hello, I was wondering if any of you might be able to help me. Today I opened my laptop and saw a message that read: Secure Boot Image failed to verify with *ACCESS DENIED* Press any key to continue.
I can enter BIOS w/F1 when I press the power key, but that seems to be the only place I can go, and most of the options are grayed out. I pressed F11 on startup in an attempt to restore the system, but all I'm able to get is a stationary white cursor line in the upper left corner of a blank screen. Any suggestions would be much appreciated.
(Background: My computer is a Lenovo Thinkpad X1 Carbon, and I was running Windows 8 until the free Windows 10 upgrade came out a few months ago. I haven't installed anything in a while except Windows and Lenovo updates. I've had a bit of a heating issue, so eight days ago I replaced the thermal paste. The machine's been running much cooler, but I've been experiencing random hibernations--usually once every 3 hrs. or so, but occasionally two in 15 min. A few of those times, I had a message that said something about my battery not being detected, and this happened both when the computer was plugged in and when it wasn't. It still charged like normal.)
