    Please don't listen to these people telling you to disable secure boot; this is used to stop malicious drivers or rootkits. If you're getting this error you need to figure out what caused it, not just turn off your security.

    I am experiencing this issue as well on a Venue 8 Pro.  Secure boot enabled = invalid signature, secure boot disables = prompt for bitlocker key.

    Searching for a way to re-generate the signature, but have not found one yet.

    Experienced this with the Venue 8 Pro as well. Seems like I installed some optional win8.1 updates and after the 2nd reboot, secure boot is bricked.

    I have the same issue as Terri-Lyn.  Looking for someone to explain how to actually fix the issue so I don't have to enter my bitlocker recovery key every time I boot my Dell Venue 8 Pro.  If I re-enable boot security in the BIOS I continue to get the boot failure/red screen of insecurity.
