Operating system must be loaded first so that other applications and programs will be able to work.
The Operating System (OS)
The operating system resides in secondary memory i.e., hard disk.when we boot our computer it is loaded into Primary memory i.e.,RAM and then loaded,this process is called booting
it is loaded on the ram of a computer ( memory ) and it is also loaded on a partiton of your hard drive if your operating systemwas installed when you broiught it it is partitiion 1
System software that is responsible for the functioning of all hardware parts and their interoperability to carry out tasks successfully is called an operating system (OS). OS is the first software to be loaded into computer memory when the computer is switched on and this is called booting.
The memory must be available, so no operating system can be loaded. Though technically there is no reason why you cant run it from a hard disk.

The operating system is loaded into the computers internal memory (RAM) at start-up. The operating system needs to 'reserve' chunks of memory to enable it to perform its functions swiftly and accurately. If a computer doesn't have enough RAM, the computer cannot run the operating system efficiently, often using empty hard-disk space - which slows down the computer.
