What have you tried: kali linux installed
What is the error: shell> …command
What device is this on: startup.nsh
Not kali related, it appears you did something to the bios of your machine you should not have done.
Consult the resources from its manufacturer or your favorite search engine
Thanks for the input! I didn’t expect that to be the issue. I’ll check the manufacturer’s resources and look for more info online to see what might have gone wrong with the BIOS. Appreciate the advice!"
