the bootloader ntldr/bootmgr-- > generates a multi-system boot menu based on the profile BOOT.INI/BCD and loads the corresponding system based on the path stored in the selected system and configuration file. (The so-called chained load, the master boot record is to find the partition where the system resides, i.e. the active partition)　　For UEFI start-up,the main process for UEFI+GPT is power-on self-test, scanning the storage device according to boot order, reading the FAT format of the

partition table, supports only hard drives with capacity below 2.1TB. Drives exceeding 2.1TB can only manage 2.1TB, up to 4 primary partitions or three primary partitions and one extended partition, with multiple logical partitions under the extended partition. 2. GPT partition table: GPT, globally unique identity partition table (GUID Partition table), GPT has no limit on the number of partitions compared to the MBR maximum of 4 partition table entries, but Windows Max supports only 128 GPT pa

The difference between EFI and MBR startup Large hard disk and WIN8 system, let us from the traditional bios+mbr mode upgrade to UEFI+GPT mode , now buy mainstream computer, are pre-installed WIN8 system, in order to better support 2TB hard disk, faster start Win8, Pre-installed systems are formatted with GPT partitioning, and the motherboard BIOS supports UEFI boot .introduction to MBR and GPT:MBR and GPT are two different partition forms, like

mount and read the second stage of the code.Note: Because the bootloader code is small, you cannot drive advanced features, such as Lvm,raid. Then the/boot file cannot be placed on the logical volume. The kernel files can only be placed on basic disk partitions.EfiThis is also a bootstrap program that is made up of Intel developed its own underlying program to replace the BIOS. The BIOS assumes responsibility for initializing hardware, detecting hardware functionality, and booting the operating
