What was before ms-dos? PC-DOS was before that. CP/M on the Z80's... Anything older than that couldn't be called an "Operating System" as we know it.

The earliest operating systems were developed in the late 1950s to manage tape storage, but programmers mostly wrote their own I/O routines. In the mid-1960s, operating systems became essential to manage disks, complex timesharing and multitasking systems.
Today, all multi-purpose computers from desktop to mainframe use an operating system. Special-purpose devices (appliances, games, toys, etc.) may or may not. Instead, they may employ a single program that performs all the required I/O and processing tasks.
Common Operating Systems
The primary operating systems in use are the many versions of Windows (95, 98, NT, ME, 2000, XP), Macintosh OS X, Linux, the many versions of Unix (Solaris, AIX, HP-UX, etc.), OS/400 (IBM iSeries) and z/OS (IBM zSeries mainframes). DOS is still used for some applications, and there are other special-purpose operating systems.
MS-DOS, is the name given to Microsoft's Disk Operating System, from which came all the Windows. It was just called DOS or disk operating system until Bill Gates and Paul Allen gave it a specific name.

Which hardware platform are we considering here? Personal computers (or something like them) are relatively new.
How much do you know about computer systems and operating systems? Are we starting with the ENIAC?
I started with MFT in 1966. OS/360 MFT was the name of the operating system.
You truly do need to do your own homework.

I'd answer this question, except that it appears to be a homework problem. If that's the case, then please do your own research; you'll learn more.
