Hello, my Dell Lattitude 7280 recently lost charge and then asked for a Bitlocker code.

I couldn't find this so proceeded to mess around with somw of the uefi settings. This bypassed the bitlocker code but now I keep getting the pictured attached.

I've downloaded Windows 10.iso from Windows and unable to boot from USB.

What am I missing, is there a step by step to follow?

First ensure there’s no USB drive connected & restart the PC. If the same then the HDD/SSD has lost the boot partition or has been changed from UEFI to the old MBR. What did you exactly do to the UEFI? Can you access the BIOS to change it back?
Chances are you’ll require installation media to repair the problem.

I actually don't know what I have done but this is my boot sequence. I've tried downloading Windows onto a USB and it dosnt want to have any of it.

I can access bios....
 
If the message appears when there’s no usb devices connected then the HDD may have failed.
If you force restart 3 times does the pc reach the troubleshoot menu?
