🔑BIOS and UEFI are firmware that allow the operating system to interface with the hardware of the motherboard.
🔑UEFI supports drives larger than two terabytes and is designed for GPT partitioning.
🔑GRUB 2 is the bootloader used in Linux systems and can boot different operating systems.
🔑Initramfs is a temporary file system that loads the necessary kernel modules during the boot process.
🔑The Linux boot process starts with the BIOS/UEFI, followed by the GRUB 2 bootloader, and then the initramfs.
What is the difference between BIOS and UEFI?
—BIOS is older and stores its configuration on the motherboard, while UEFI is newer and stores its configuration on a partition of the hard drive.
What is GRUB 2?
—GRUB 2 is the bootloader used in Linux systems. It allows you to choose which operating system to boot and can boot from various sources.
What is initramfs?
—Initramfs is a temporary file system that is loaded during the boot process. It contains the necessary kernel modules to mount the full file system.
What is the Linux boot process?
—The Linux boot process starts with the BIOS/UEFI, followed by the GRUB 2 bootloader, then the initramfs, and finally the full file system.
Can GRUB 2 boot different operating systems?
—Yes, GRUB 2 can boot different operating systems. It allows you to choose which operating system to boot during the boot process.
