Downloaded an ubuntu and then mint distro today put them on a usb and was able to load them. Went through the install process to put Linux on a separate usb and two other external hard drives at different times and removed the original usb. went into the bios to boot from said drive and each time I get no operating system found. messed with some settings but no change. boots into windows fine every time. Trying to make a mobile Linux that I can take with me. I know I'm very new to this but it's been frustrating me all day that I can get a "Try Ubuntu" to work but not a proper install. Assume that I know nothing and I'll try to keep up. Thanks for the help if you need any automotive advice I can give my opinion on that.
