Dell T7610 - Accidently turned on Secure Boot!

Hi @QuantGeek ,

A BIOS reset as described in this thread should solve you problem:

1. Power off and unplug
2. Press/hold power button for ~15 sec
3. Open case and remove motherboard battery
4. Press/hold power button for ~30 sec
5. Reinstall the battery (right-side-up!)
6. See if it boots now with only mouse, monitor and keyboard connected

Your GPU is not UEFI compatible?

The video card is a Radeon Pro WX 7100 Graphics Card!  So, I don't know why it doesn't work.  The Secure Boot is what is probably screwing it up.  I need to turn it off, but the above thread indicates that the BIOS can't be reset by removing the battery?  I am going to try it to see if it works...

How do I remove the CMOS battery from its "secured" position?

Its not like what the manual says:

Hi @QuantGeek ,

Checked picture of T7610 motherboard, like this.

Put a small screwdriver into hole on the right side and slightly push it to the left, then the battery will come out.

Please note that turning Secure Boot back on may require a BIOS reset. This does not cause your system to lose any data. It does, however, remove any custom BIOS settings. Moreover, there are some examples where users are permanently no longer able to turn on Secure Boot, so please bear that in mind.

Okay, here’s what you do:

1. Turn your computer off. Then, turn it back on and press the BIOS entry key during the boot process. This varies between hardware types, but is generally F1, F2, F12, Esc, or Del; Windows users can hold Shift while selecting Restart to enter the Advanced Boot Menu. Then select Troubleshoot > Advanced Options: UEFI Firmware Settings.
2. Find the Secure Boot option. If possible, set it to Disabled. It is usually found in the Security tab, Boot tab, or Authentication tab.
3. Save and Exit. Your system will reboot.
