In this release an optional workaround has been implemented to make buggy BIOSes happy when they think that devices without partition boot flag toggled isn't bootable.
To enable this workaround you need to specify --workaround-bios-boot-flag in the WoeUSB command-line, the first partition's boot flag will be set after applying this workaround(which partition has the boot flag doesn't matter).
