I'm trying to have OMV run from a usb stick on an old laptop to test things out. When it load I can successfully enter the boot menu to select USB, but the OS on th HDD always loads anyway.
I created the usb stick with Etcher for windows with this iso file.
My old laptop is a Toshiba Satellite L870D currently running LibreELEC.
I'll be glad to provide more information if need be,
Thank you
