@Jam2509 Welcome to HP Community!
I understand that you are getting error Cannot open bios signature file message while rollback the BIOS.
Do not worry. I will try to fix the issue.
You can try to manually perform a BIOS recovery by following these steps:
Turn off the computer.
Plug the notebook into power using the power adapter.
While the computer is still off:
Press and hold the Windows key and the B key at the same time, and then press and hold down the Power button on the notebook for one second.
Release the Power button and the keys.
By following these steps the BIOS will reach the UEFI partition in order to recover the BIOS to the last known good version of the BIOS from the hard drive. Let me know how it goes.
