METHOD AND SYSTEM FOR INSTALLING OPERATING SYSTEMS (OS) ON
TARGET NODES
TECHNICAL FIELD
[0001] Embodiments of the present disclosure generally relate to an operating system installation method and system. More particularly, embodiments of the present disclosure relate to methods and systems for installing one or more operating systems (OS) on one or more target nodes.
BACKGROUND
[0002] The following description of the related art is intended to provide background information pertaining to the field of the disclosure. This section may include certain aspects of the art that may be related to various features of the present disclosure. However, it should be appreciated that this section is used only to enhance the understanding of the reader with respect to the present disclosure, and not as admissions of the prior art.
[0003] An operating system (OS) is responsible for managing a plurality of resources of a computer. The OS acts as an interface between a software and a plurality of components of the computer or a computer hardware. The OS has the ability to manage multiple resources and multiple operations of the computer. The OS is a fully integrated set of specialized programs designed to handle plurality of operations of the computer such as inputting, processing, outputting, storing and controlling. The OS controls and monitors an execution of one or more programs that are stored in the computer such as application programs. Further, the OS is a collection of software for managing one or more computer hardware resources and provide a set of services for the computer programs.
[0004] Additionally, the OS in the computer helps the computer to be user-friendly as the OS provides an interface to a user which makes the application user-friendly. The OS includes a plurality of device-drivers and makes the OS reachable to a hardware environment. Hence, each application present in the computer requires the OS. Further, there are plurality of functions of the OS such as a resource management function, a process management function,

a memory management function, a security function, a file management function and a device management function.
[0005] While the OS plays an important role in user friendliness and functionality within the computers, however the installation process of the OS extends beyond individual systems to one or more servers and one or more network environment for supporting multiple workstations and terminals which are connected on the network such as local area network (LAN). For instance, the OS may facilitate two or more nodes to share one or more resources.
[0006] Conventionally, the OS is installed in the computer manually by an operator. The manual process of installation of the OS, choosing the OS, choosing a backup of a data, choosing an installation media, configuring the OS, and the restoring the data. Moreover, the manual installation of the OS additionally involve logging into an Out-Of-Band (OOB) graphical interface (GUI), setting one or more boot configurations, attaching a standard image uniform resource location to a virtual media, rebooting a server and manually selecting one or more option while the server is rebooting. However, the OOB-GUI does not download the standard file immediately, but rather streams the standard file from the uniform resource location as the OOB installs the OS. Hence, the installation speed of the OS depends on a network bandwidth and latency. Moreover, manual interventions are also required during the installation of the OS, which delays a deployment process. Also, the manual interventions lead to inefficiency and potential errors in the deployment process.
[0007] Further, over the period of time, various solutions have been developed to automatically install the operating system on a set of target nodes. However, there is no solution that exists in the market which provides a fully automatic way of installing the OS. Hence, in the current existing solutions, the manual interventions are required. However, there are certain challenges with existing solutions such as potential errors due to the manual interventions, delay in the deployment process, heavy dependency on the network bandwidth and latency which hinders an overall efficiency.
[0008] Furthermore, in scenarios where the network connection is slow or unstable, the OS installation process could be significantly prolonged or even disrupted. The lack of immediate standard file downloading adds an extra layer of complexity to the installation procedure. The currently known solutions require a continuous network connectivity and a reliable access to

the image Uniform Resources Locater (URL) throughout the installation process, leaving the system vulnerable to potential interruptions or failures in the network connection.
[0009] Thus, there exists an imperative need in the art to provide a solution which automatically installs the operating system on a set of target nodes.

[0050] FIG. 1 illustrates an exemplary block diagram of a computing device [100] upon which the features of the present disclosure may be implemented in accordance with exemplary implementation of the present disclosure. In an implementation, the computing device [100] may also implement a method for installing one or more Operating Systems (OS) in one or more target nodes utilising the system. In another implementation, the computing device [100] itself implements the method for installing the one or more Operating Systems (OS) in the one or more target nodes using one or more units configured within the computing device [100], wherein said one or more units are capable of implementing the features as disclosed in the present disclosure.
[0051] The computing device [100] may include a bus [102] or other communication mechanism for communicating information, and a hardware processor [104] coupled with the bus [102] for processing information. The hardware processor [104] may be, for example, a general-purpose microprocessor. The computing device [100] may also include a main memory [106], such as a random-access memory (RAM), or other dynamic storage device, coupled to the bus [102] for storing information and instructions to be executed by the processor [104]. The main memory [106] also may be used for storing temporary variables or other intermediate information during execution of the instructions to be executed by the processor [104]. Such instructions, when stored in non-transitory storage media accessible to the processor [104], render the computing device [100] into a special-purpose machine that is customized to perform the operations specified in the instructions. The computing device [100] further includes a read only memory (ROM) [108] or other static storage device coupled to the bus [102] for storing static information and instructions for the processor [104].
[0052] A storage device [110], such as a magnetic disk, optical disk, or solid-state drive is provided and coupled to the bus [102] for storing information and instructions. The computing

device [100] may be coupled via the bus [102] to a display [112], such as a cathode ray tube (CRT), Liquid crystal Display (LCD), Light Emitting Diode (LED) display, Organic LED (OLED) display, etc. for displaying information to a computer user. An input device [114], including alphanumeric and other keys, touch screen input means, etc. may be coupled to the bus [102] for communicating information and command selections to the processor [104]. Another type of user input device may be a cursor controller [116], such as a mouse, a trackball, or cursor direction keys, for communicating direction information and command selections to the processor [104], and for controlling cursor movement on the display [112]. This input device typically has two degrees of freedom in two axes, a first axis (e.g., x) and a second axis (e.g., y), that allow the device to specify positions in a plane.
[0053] The computing device [100] may implement the techniques described herein using customized hard-wired logic, one or more ASICs or FPGAs, firmware and/or program logic which in combination with the computing device [100] causes or programs the computing device [100] to be a special-purpose machine.
