OK, not sure what the error is; But what I would recommend doing, if you're not already is to follow some instructions unless you know what you're doing. When you put Windows 10 on the USB, use the media creation tool to make sure you get it on the USB correctly(https://www.microsoft.com/en-us/software-download/windows10). Now plug it in and let it do that, and once it's done plug it into your PC you're trying to install Windows 10, and then when its starting up mash the BIOS button(del) or whatever it is for you to get into that and select the boot device as the USB. Once you select that go to Install Windows, after that select which drive you want to install it on, and then install, it should reboot afterwards and then you should be able to go into BIOS again, and boot from the HDD. It should work from there out, if not quote me and I can help you personally with Skype, TS, or whatever you'd like.
