I have use the start up disc creator in Ubuntu 18.04 to make a bootable USB to install an OS on a pc. Unfortunatly when I plug in the drive the PC will not boot from the drive. I have tried 3 different OS's including Ubuntu 16, 18, and Mint 19 and none of them will boot properly. I tried 4 different USB drive and still having problems with drives not booting. Am I doing something wrong or is there a problem with the startup disk creator? I appriciate any assistance. :)
You tried 3 different OS's including Ubuntu 16, 18, and Mint 19 and none of them would boot properly. So I think the problem is not Ubuntu 18.04 LTS. The following link may help, Booting the Computer from USB.
Maybe I was mislead by the information about the motherboard via the internet stating that 64-bit versions should work. Maybe you should try a 32 bit version of Lubuntu or Xubuntu.
I have two old machines with Athlon CPUs. One of them has an ASUS M2NVM_DVI motherboard, and I have tested several Lubuntu iso files on it including the 18.04.1 LTS and 18.10. Booting and running works.
You can try cloning the working operating system borrowed from your laptop (source) to the drive that is dedicated for the problematic machine (target), if the target is at least as big as the source (storagewise).

Ubuntu Startup Creator can generally make other Ubuntu startup USBs. However, I recently found I couldn't make a Centos USB using the Ubuntu Startup disk creator. I used
dd if=/path/to/Cento.iso of=/dev/sdb status=progress. Note that the destination device is the device, not a partition on the device.
