Help with reinstalling Linux Cinnamon Mint of the Dell Ghost Laptop. No Bootable Device Found

Question on how to solve no bootalble divice error.

I have lost the boot to my Dell Ghost Linux Cinnamon Mint. Started the computer and message came up, No bootable device found, with several options. Tried them all, no success. Looks like I have lost evertything. Because it is a dell that was set up with Linux, not a side by side with windows, just Linux, I’m not sure if I can just make a bootable usb stick and load it into the dell. I can’t even seem to figure out how to make a bootable disk. Can anyone on here help me? Klb
