Nothing happens on boot screen

No matter what i do on the boot screen nothing launches is there a way to revert to chromeos from this screen?? i have a usb with my backup

i would include a demonstration but it won’t allow me to upload videos or photos since i’m a new user

i tried each booting option and nothing happens it’s just a black screen, any help or how i can return to chromeos from here

Also maybe include the device name and what you did to investigate how your Chromebook got bricked.

I used an Asusc424 Nospike mother board and i followed this guide:

however when i got to the part with the boot menu nothing boots no matter what image i choose

As mentioned previously, please provide your device board name. You can find it by following the page below.

Sorry for the late reply the devices boardname is nospike
