No. Before MS-DOS ever existed, Digital Research had a disk operating system called CP/M for 8-bit Intel 8080 and Zilog Z80 based microcomputers. Bill Gates bought the original MS-DOS from a programmer at Seattle Computer Products named Tim Paterson who had developed a variant of CP/M-80 as an internal product for testing SCP's new16-bit Intel 8086 CPU card. The system was initially named QDOS (Quick and Dirty Operating System), before being made commercially available as 86-DOS. Microsoft purchased 86-DOS, allegedly for $50,000. This became Microsoft Disk Operating System, MS-DOS, introduced in 1981.
