What Is The Boot Manager And How Does It Work In BIOS?
The Boot Manager in BIOS is a crucial component responsible for loading the operating system when the computer starts up. It works by storing information about the operating systems installed on the computer, along with their corresponding boot loaders. When the computer boots up, the BIOS searches for the Boot Manager and loads it into memory.
Once the Boot Manager is loaded, it presents a list of available operating systems to the user, allowing them to select which one to boot into. The user can then choose their desired operating system, and the Boot Manager will load the corresponding boot loader, which in turn loads the operating system. The Boot Manager also provides options for configuring boot settings, such as setting a default operating system or adding new boot options.
Why Would I Need To Change The Boot Manager In BIOS?
You may need to change the Boot Manager in BIOS for several reasons, such as installing a new operating system or troubleshooting boot issues. When installing a new operating system, the Boot Manager may not automatically detect it, requiring you to manually add a new boot option. Additionally, if you experience issues with your current Boot Manager, such as it not loading the operating system correctly, you may need to reset or change the Boot Manager to resolve the issue.
Changing the Boot Manager can also be useful when dual-booting multiple operating systems. If you have multiple operating systems installed on your computer, you may want to change the Boot Manager to set a different operating system as the default. This can be useful if you use one operating system more frequently than the others. By changing the Boot Manager, you can ensure that your computer boots into your preferred operating system every time.
What Are The Different Types Of Boot Managers?
There are two main types of Boot Managers: Legacy Boot Manager and UEFI Boot Manager. Legacy Boot Manager is an older type of Boot Manager that uses the Master Boot Record (MBR) to store boot information. It is typically used on older computers or computers that use the BIOS firmware.
UEFI Boot Manager, on the other hand, is a more modern type of Boot Manager that uses the GUID Partition Table (GPT) to store boot information. It is typically used on newer computers or computers that use the UEFI firmware. UEFI Boot Manager offers more advanced features than Legacy Boot Manager, such as support for larger hard drives and improved security features.
