Another stupid noobie here that needs help, please.

Bought a refurb Asus Chromebox, and proceeded with the instructions as written for a stand alone install of Libreelec. Naturally, I did not back up the original files, because I'm thinking there is nothing to back up as it is unused.

Got all the way through the downloads without a problem and created the SD Card for the Libreelec install. When I press "ESC" to get the boot prompt, I enter "1" to boot from USB I am thinking because I told it "1" during the creation. All I get is "can't find kernal image 1" and I can't get it to boot from the SD card. EDIT: I believe the sd card is fine, because it was a refurbished model I had to load a recovery from google at the very beginning because OS was damaged. I ran the recovery and it worked fine.

Is there some other way to tell the device to boot from USB, other than hitting "1"? What do you enter at the boot prompt? There is no menu like 1=boot from hard drive, etc.

I am hoping you guys can help, because Chrome OS has been wiped from my hard drive and I think it's a paperweight if this don't work! All I get is a black screen if I press the recovery button from power off.

Thanks for your help if you can.

At the SeaBIOS boot menu, you need to select the number that corresponds to the USB/SD card from which you wish to boot (Note: SD cards will show up as a USB device since the card reader is a USB device). Assuming you didn't choose to default to USB when installing the firmware, the USB/SD card will be option #2, as here:
.

The fact that you chose device #1 when creating the install media has no bearing at all (since the internal SSD wasn't an option then).

If the LibreELEC installer you created with the script won't boot for some reason, then download the LibreELEC SUB/SD creator tool on another machine and use it to create the install media, ideally on a different USB/SD device.
