I have installed galliumOS onto a USB flash drive using Win32 Disk Imager, still exactly the same when i boot, OS verification page followed by seabios followed by blank screen

so how did you manage to boot the ChromeOS recovery media? And if you can still do so, then we can possiblyre-run the script from there and set your GBB flags back

I booted it using the recovery media on usb but as I said before it just took me to a blank screen or a screen with the chrome logo and nothing else, with the gallium am I supposed to do anything in particular when I boot up, put the USB in before I power up e.g?
