Help! Secure Boot Image failed to verify with *ACCESS DENIED*

If you cannot remove the secure boot you won't be able to boot to anything but the system.
Are you certain you cannot disable secure boot and enable legacy boot, that way F12 or F9 should work so you can boot to cd or usb flash drive.

 

^Yeah F12/11 and select your CD rom as boot and if you have the restore disk -- restore the OS to factory, or you can do a non destructive restore as well to keep your data.

Edit: if this does not work I recommend taking it to an Authorized IBM/Lenovo repair facility and seeing if you can get them to either clear CMOS and reset defaults, or similar, and look for your "legacy" option and for a BIOS update.

What I am thinking is that by updating to Windows 10 your graphics adapter is now seen as a Secure Boot only GPU, and/ or that your model for some reason isn't fully compatible with the Win 10 upgrade unless you are able to use a legacy mode within the BIOS. I do think that by merely reloading the Original operating system yous BIOS would then function correctly with the laptop hardware. So my final advice : Take it to an authorized IBM/Lenovo relair shop let them do this for you. It could be that the BIOS would need an update for the Windows 10 to work correctly with the BIOS.

 

Linda do you have any new information for us?
