LM20/Win10 Dual Boot No GRUB

I am trying to return to Linux with LM 20 Cinnamon. The install went very well but when I rebooted I booted right into Win-10. There was no GRUB screen... no choice. When I went into the UEFI settings, only Windows is listed. During the install after I was finishing creating the partition layout I selected Windows Boot Manager as the device for installing the boot manager and committed changes to disk.

How do I get to the GRUB or to have UEFI to see Linux?

Any help is appreciated,
Ed
