Types of Booting In Computer

Booting is the process of loading an operating system into a computer’s memory, usually from a hard disk and sometimes from a soft disk. Important types of booting process are Cool Boot, Warm Boot, UEFI Boot, and Legacy Boot.

What is Booting in Computer?

Booting is usually an automatic process that starts or resets the system. The set of commands (read-only memory) in ROM starts executing. Desenurat performs a set of POST-self-tests to confirm the proper functioning of gadgets such as hard disks, then detects and loads the operating system. Finally, they give control over the operating system.

• UEFI Boot
• Legacy Boot

What Is Cool Booting?

Turn on the computer and load the operating system while the operating system is running. In the process, several hardware tests are performed routinely, and then the operating system is loaded from disk to memory.

What is Warm Booting?

It is one of the most important types of booting processes in which users have to restart the computer so that it does not need to be turned off and on. This process usually means reloading or reloading the operating system. On IBM and compatible systems, the user can perform quick start operations using the CTRL-ALT-DEL key combination.

UEFI Boot

UEFI stands for Unified Extensible Firmware Interface. The UEFI is the last way to boot a computer designed to change the BIOS. UEFI is a new boot system that addresses BIOS limitations. Most new motherboards are made this way. It has advantages over using BIOS.

More importantly, it provides an easy-to-use Graphical User Interface (GUI). The BIOS provides a blue screen with various options. A typical BIOS cannot detect large storage drives. UEFI offers a good alternative to this and can detect large storage drives.

In a typical BIOS that uses the keyboard to select options, UEFI lets you control the interface with a mouse. UEFI also includes a secure boot. These types of booting processes avoid loading unsigned digital drives and help prevent malware. Some UEFI-equipped computers allow the user to turn on BIOS Legacy Compatibility Mode.

UEFI boot uses the UEFI operating system. EFI maintains a list of valid boot units called service partitions. While the self-test (deployment) is valid to verify that all devices are working properly, the UEFI operating system checks all bootable storage devices connected to the system with a verified partition table (GPT). there.

Legacy Boot

LEGACY booting is the process of booting the system using the BIOS operating system. Saves a list of bootable storage devices such as floppy disks, hard disks, and optical drives in order of priority.

When power is connected to the system, the BIOS performs its own power test. Then a short beep sounds to indicate that the built-in speaker function is normal. The beep code helps to identify the code and perform troubleshooting exercises.

After completing the POST mode, the operating system loads the first part of each storage target into memory. It then scans for the correct master boot record (MBR). If the correct MBR is found, it sends the operating system to the boot loader to select the partition to boot. If no one is found, it will move to the next device in the boot queue.

Features Of Legacy Boot

Legacy boot system supports MBR disk, its features are as follows:

• Supports up to four primary partitions.
• This disk does not support more than 2 TB.
• An operating system boot record can only be stored on an MBR.

Difference Between Cold Booting And Warm Booting

Cold Booting and Warm Booting are two different types of booting in computers. Click here to know the differences between cold booting and warm booting.

Difference Between UEFI and Legacy

The main difference between UEFI and LEGACY boot is that UEFI is the last method of booting the system designed to change the BIOS, while the LEGACY boot is the process of booting the system using the BIOS. It is a new boot system that addresses BIOS limitations.

Heritage boot mode, as its name implies, is a type of traditional boot mode. It is popular types of booting process on pre-Windows 8 Windows systems. It has good compatibility and can be used on both 32-bit and 64-bit systems.

UEFI is a boot processor on modern computers that provides advanced BIOS capabilities. The legacy boot is the process of booting your computer using the BIOS. This explains the basic difference between UEFI and Legacy boot.

Ability

UEFI also uses the operating system URFI, which maintains a list of valid boot modules called EFI service partitions for the boot process. Conventional boot using the BIOS for the boot process.

Feature

Another important difference between UEFI and Legacy boot is that UEFI has additional security features and is more efficient than Legacy boot. More suitable for UEFI users than Legacy Lock.

Check Bootable Storage

While UEFI uses the GUID Partition Table (GPT), the BIOS uses the Master Boot Record (MBR) Partitioning Scheme.

Last words

The difference between UEFI and Legacy boot is that UEFI is the last method of booting the system designed to change the BIOS, while the Legacy boot is the process of booting the system with the BIOS. In short, UEFI changes the BIOS.
