 Others have reported this error from a failed boot drive, e.g.,

It can be helpful to try booting a live Linux distro.   If it works then
you can try reinstalling MacOS.   I had a similar vintage macbook pro with
failed graphics hardware.  MacOS refused to run, but Ubuntu was able to
boot to a text console from which it is possilbe to tweak the configuration
to work around the failed hardware.    Linux `dmesg` often has details of
hardware issues found at startup.
