Sorry for top posting. Sounds like your BIOS will read the botox64.efi from the removable USB drive, but won't from the hard drive. Force BIOS booting instead of UEFI and it will install correctly. However, it may not boot Windows, which I think requires UEFI these days. The root of the problem is that we have no way to setup the EFI boot variables in the installer that we need to properly installed under UEFI. I'm working on that, so you'll need to be patient...
