error when trying to run "balena" command

I’m getting error when trying to execute this command:
$ balena os configure /home/admin-jetson/Desktop/gate_report1.config.json --fleet gate_report --version 15.2.0

ERROR:
Invalid MBR boot signature. Expected 0xAA55, but saw 0x0

Please any idea?

Hello, it looks like you are missing the path to a balenaOS image file which should be the first argument. Instead, you have the path to a config file, but without the --config option. So you’d want something like this: balena os configure /path/to/image.img --config /home/admin-jetson/Desktop/gate_report1.config.json --fleet gate_report --version 15.2.0
Please see this doc for more details: balena CLI Documentation - Balena Documentation
