Changing the boot order can be useful in situations where you need to boot from a CD/DVD or USB drive to repair or reinstall the operating system.
What is a boot loader, and how does it work?
A boot loader is a small program that loads the operating system into memory when the PC starts up. The boot loader is responsible for identifying the operating system and loading it into memory, allowing the system to boot correctly. The boot loader is usually installed on the hard drive’s master boot record (MBR) and is executed by the BIOS during the boot process.
In a typical boot process, the BIOS searches for a boot loader on the MBR, loads it into memory, and executes it. The boot loader then searches for the operating system and loads it into memory, allowing the system to boot correctly. However, if the boot loader is damaged or corrupted, the system will fail to boot, displaying an error message or failing to recognize the operating system.
