Mid-2011 and later include UEFI support, and Microsoft requires that PCsīearing a Windows 8 logo ship with UEFI (and a specific UEFI feature knownĪs Secure Boot) enabled. Among common computers, Apple Macintoshes are the systems Unfortunately, EFI is stillįairly rare on the installed base of mainstream PCs, but most new PCs are GPT is part of the EFI specification, so of course booting from GPTĭisks becomes easier if your computer uses EFI. BIOS booting booting with EFI and booting with The rest of this page is broken down into three main sections: Keep in mind, though, that these details are Support for booting from GPT is limited compared to support for bootingįrom MBR, although this is changing rapidly with the adoption of UEFI. One of the challenges of GPT is that of booting from it. Note: This page is part of the documentation for my GPT fdisk program.

In the second step, the bootloader loads the kernel of the operating system, that is, the primary component of the system software that controls all storage and processor permissions and contains all important drivers. The first task is to load the main memory, which is essential for the processor to work. As soon as a bootloader has been initialized by the respective firmware, it has system responsibility to get the boot process going.

For devices with UEFI, for example, the format is PE/COFF ( Portable Executable / Common Object File Format).īootloaders serve as a mediator between hardware and the operating system. The decisive factor here is always the firmware, which stipulates a specific file format for the boot manager in this bootloader storage model. In the second case, the operating system uses a selected partition as the storage location for the bootloader, though the underlying file system and the partition tables used can vary greatly.

Because of this important function, it is also known as the boot block or boot sector. The first available memory block or sector in the medium is always reserved for the record. The first variant is closely connected to the principle of master boot records, which don’t just contain the link to the bootloader required by the firmware, but the boot software itself.
