    If you have access to another Mac, you could create a usb high Sierra installer.

    If your computer was running high sierra, the boot rom will have been updated so that holding CMD+Option+R will automatically go to system recovery for the latest supported MacOS version. If you do Shift+CMD+Option+R you will get the original OS it shipped with or the oldest still available.
