First off, I am a complete newbie and with that disclaimer, I am concerned that I bricked my Asus Chromebox M107U. In efforts to install dual boot with OpenELEC, I went to reboot and my USB ports are no longer active. The following is what appears:
__________________________________________________________________________________________________________
SeaBios (version -20141003_164257-build122-m2)

Press ESC for boot menu (as keyboard no longer works, I wait and then the following flashes on the screen before going black. Captured text with Slo-Mo on iPhone).

Decompressing Linux..... Parsing ELF.... Performing relocations... done.
Booting the kernel.
___________________________________________________________________________________________________________

Screen goes black and nothing. When I press the Recovery button and power on, I get the Chrome window with message that Chrome OS is missing, etc. In the upper left, I have the following script

gbb.flags is nonzero: 0x00000489
read-only firmware id: Google_Panther.4920.24.26
active firmware id: Google_Panther.4920.24.26

Inserting a ChromeOS recovery image on USB is non-responsive.

Does anyone have any helpful advice as to next steps ? Being the newbie, I have neither the tools nor the expertise to flash the firmware but am willing to take any advice and give it a try (minus hating on iPhones).

Thanks
