Windows 7 did this. If your drive was empty, during partitioning it says it might add another drive for system recovery utilities and such. That's what this 100MB partition is for. | | My System Specs | | System Manufacturer/Model Number Self-Built in July 2009

Actually AFAIK the boot manager doesn't live there but in one of the bootable partitions (designated as System), but there are recovery & repair tools and such.
