USB Ubuntu installation fails - BOOTMGR is missing

Trying to install Ubuntu Linux using a bootable USB [pen] drive will result in nothing but the message "BOOTMGR is missing" after selecting to boot from the USB drive if the drive is not formatted with the FAT32 filesystem. This is the case even if you use UNetbootin, which only copies files and does not format the drive. You should not stumble into this problem if you use Rufus, although using that may require changing the version of Syslinux that Rufus is using.
