Sorry Michael, I copied the .rbf to lib/firmware/socfpga and I used the full path when I did the "setenv bitimage …".
I ran make dtb on the QuartusProject. It produced soc_system.dtb and soc_system.dts in the project directory. When I did "env default -f -a" it restored the fdtfile to socfpga_cyclone5_de10_nano_fb.dtb and when I tried booting it I was able to boot again. I wish I understood what the device tree blob is accomplishes, that would make it easier to avoid these errors. I am thinking about buying a small LCD monitor say (16” 1366x768). So that I can have a monitor on the putty console at the same time I am trying to see if the de10-nano is booting into the desktop. Right now I can’t easily switch between the x86 linux desktop and the de10-nano desktop to see if I am being successful or not. When I turn off my development box and try to boot the de10-nano desktop I am not seeing anything, the monitor just reports no signal.
