My solution is to get Rufus 2.8.886 bootable usb maker (it's free) and run through the usual configure, however when you select your linux ISO file, choose in Rufus the "DD" mode which in layman's terms means to simulate a HDD so that the computer and installer don't get confused but partitions and file types. Don't worry if you can't see the prepared DD type USB drive in windows file explorer, you will only see a couple .EFI files. Just boot off the USB drive as usual and it will properly install the bootloader.
