If you're the lucky owner of an Intel Galileo board then you'll probably know that the device has an 8MByte flash chip, which contains the BIOS and a Linux boot image (even the ones that MS shipped apparently). Sadly, it is possible to accidentally trash the contents of flash chip rendering the device unbootable. The good news is that it is possible to recover the device if you have hardware that talks SPI. That could be a BusPirate, a BusBlaster, a PICKit2 (Linux only) or one of the many FT2232 SPI or JTAG boards.
