+The MBR partition table on the SD card should contain one bootable FAT32 partition. Use `fdisk`, `cdisk` or `sfdisk` to create this scheme. Some examples of a SD card located in `/dev/sdc`.

+Warning: If you do not know what you are doing here you should NOT do it or accept the risk of potentially loosing ALL your data including those of the host system.
