Upon powering on, most computers will begin by reading data stored on the internally located hard disk. On the other hand, you will have to modify your computer’s boot order to prioritize booting from a DVD or USB drive.

A Boot Sequence: What Is It?

The computer does a self-check, loads the operating system, and loads some minimal operational applications during boot.

The term “boot sequence” describes the initial set of steps that a computer takes whenever it starts up. The computer performs self-checks, activates hardware, loads operational software, and finally loads the operating system during the boot procedure. This allows the user to interact with the machine.

A computer’s boot sequence—also known as boot options or boot order—defines the devices for which the operating system’s boot files and startup should be checked. A computer’s boot sequence—also known as boot options or boot order—defines the devices for which the operating system’s boot files and startup should be checked. It goes on to detail the procedure for checking each component of the computer.

The boot sequence consists of the following steps:

1. Booting up a computer starts with gaining access to the system ROM or BIOS, depending on whether you are using a Mac or Windows PC. The computer’s fundamental boot instructions are located in the BIOS and ROM.
2. The computer central processing unit (CPU) gets starting data: The central processing unit (CPU) receives these instructions from the BIOS/ROM.
3. Data was received by the computer’s memory: Computer memory received information: Data is subsequently loaded into the system RAM by the CPU.
4. After the computer detects a bootable disk, often known as a startup disk, it starts loading the operating system into system memory.
5. Upon completion of the operating system’s loading process, the computer is prepared for usage.

The time it takes for the computer to boot up might range from a few seconds to a few minutes, all depending on its configuration. Keep in mind that the boot time could be much longer when the system is starting from a CD or DVD rather than a hard disk.

The system may execute extra checks to ensure everything is OK, which could cause the boot time to rise if your computer was shut off unexpectedly. On the other hand, there could be some boot issues in your computer you also need to check out.

How should I start my computer?

Customize the way your computer boots by adjusting the boot sequence. For example, the hard disk need to be the initial boot device if you never intend to boot from a disc drive or a portable device.

Take into consideration that modifying the boot sequence can be necessary while attempting to repair or reinstall an operating system on a machine. When performing these types of operations, the most common initial boot options include an optical disc drive or a detachable drive (thumb drive).

The computer’s BIOS allows you to rearrange the boot order list, as demonstrated below.

Instructions for Altering the Sequence of System Boot

The BIOS setup utility is where you can alter the boot order of your machine. Here are the steps to follow to find out:

The instructions below are meant to provide broad guidance only, as this can differ between different PCs. Please contact the manufacturer for clarification if you are uncertain.

First, launch the BIOS setup program on your computer.

• It is common practice to press a key (or multiple keys) while booting up a computer in order to access the BIOS.
• Restart your computer and pay close attention to the information displayed at the beginning of the startup process if you are unsure of which key to press. You should see a prompt that says “Press XXX to enter setup” or along these lines.
• Restart your computer and try again if you do not press the setup key fast enough before the computer starts loading from the internal disk.

Attention: In the event that you are unable to locate the necessary information regarding the key to press, Lifewire has compiled a helpful reference encompassing the most frequent keys utilized by various computer systems and motherboards. You may wish to peruse this guide.

Second, in the BIOS, find the boot order menu.

• To alter the boot sequence, go to the BIOS setup program on your computer.
• Although each BIOS utility is a little bit different, you can find it under the Boot, Boot Options, Boot Sequence, or Advanced Options menus.

Important: Some BIOS utilities may not allow you to use a mouse, so be sure to follow the on-screen prompts to select the options you need.

Third, rearrange the boots.

• After navigating to the BIOS page that allows you to change the boot order, you will be able to see a variety of possibilities from which your computer can boot.
• Although the exact choices may vary greatly from one system to another, common ones include Hard drives, optical (CD or DVD) drives, removable devices (such as USB or Floppy), and networks.
• Arrange the items in the list so that USB devices or removable devices are at the top.

Move on to Step 4: Save Your Modifications.

• If you want your modifications to stay after you quit BIOS, you must save them.
• Find the “Save Changes” or “Exit with Changes Saved” (or comparable) option in the Save and Exit or Exit menu, and select it.
• As you are about to quit BIOS, you can see a confirmation notice. Be sure you are selecting the right option to confirm the changes by reading it thoroughly.
• After you quit BIOS, your machine will restart itself.

Ending Remarks

You now understand that a computer’s boot sequence is the order in which it looks for nonvolatile data storage devices that have the software needed to load the operating system (OS). To initiate the boot process, a Windows PC typically makes use of BIOS, whereas a Macintosh system makes use of ROM. We trust this information is helpful.
