The No. 0 Sector of the GPT disk retains the partition table and the "55AA" flag, but only one partition table entry is used to describe a partition with an entire disk size and a partition type of 0xEE.
Because GPT disks back up important information about disks and partitions at the end of the EFI section, if only the EFI information and partition tables in the front of the disk are compromised, copy the

If you are unfamiliar with these special terms, I would simply explain: MBR and
In fact, a few articles on Uefi wrote very early, just read it once and feel very dissatisfied, decided to rewrite. The goal is to write the content in the simplest and most straightforward language so that everyone can read it easily. Of course, if you have a deep understanding of the content, this article in addition to wasting your time is probably no good, it is recommended to go to the UEFI official website to download the UEFI specification document, where detailed description of UEFI,
MBR and GPT partition table detailed
Before a new hard disk (uninitialized) system is installed, the partitions must be aligned, and the hard disk partition initialization format includes MBR and GPT two. There are, of course, a special Apple partition map for PowerPC based Mac computers, which is not covered here.
the full name of the MBR is the Master boot record (master boot Records
How is the hard disk MBR format converted to GPT format? This is a lot of small white computer users do not understand. First, on the hard drive GPT format, GPT is a globally unique identity partition table (GUID Partition table, abbreviation: GPT), which refers to a globally uniquely labeled Disk partition table type.
understand the GUID partitioning scheme. Don't forget, the speed of hardware development is always surprising. 1.5TB of hard drives are already on the market, 2TB or more of the capacity of the hard disk will soon become popular, EFI-based motherboards are also being sold. The GUID partitioning scheme will eventually become mainstream.As a section software,DiskgeniusThe GUID partition table is supported starting with version 3.1. This is the first partition software that supports GUID partition

Basic knowledge of secure boot in MBR, GPT, ESP, MSR, EFI, Uefi, and WIN8:1.MBR partition table: Master boot record, which is the hard drive master boot Record 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.
, Now forming part of the UEFI standard. Its increasing popularity are easily understandable, as it provides several benefits over the traditional PC master boot re Cord (MBR) scheme. Furthermore, people using Intel based Apple products (like MacBooks) would most likely is using GPT (with a hybrid MBR sche Me). While the Internet was full of documents that go to the details of this format, there is a few benefits worth mentioning Here

Objective: To generate a large number of cases of simulating broken GPT partition structure, and to generate a unique method for the evaluation of the post-repair.Failure: On a full GPT partition disk, the GPT Primary partition table is missing or the partition table is backed up.Requirements:1, using Winhex manual method, repair the partition structure of the gi
partition table in EBR describes the first logical partition, and the second item points to the EBR of the next logical partition. If the next logical partition does not exist, the second partition is not required.
The structure of the MBR partition is roughly described here. If the MBR of the hard disk is damaged, you can copy the MBR of another hard disk to the faulty disk, repair the partition table, or initialize the faulty disk and then repair the partition table.

When you set up a new disk in Windows 8 or 8.1, you are asked whether you want to use an MBR or a GPT partition. GPT is a new standard and is gradually replacing the MBR.GPT brings a lot of new features, but MBR still has the best compatibility. GPT is not a new standard for Windows-specific--mac OS X,linux, and other operating systems use
Computer Driver MBR GPT
GPT protection partition:A disk partition architecture used by the extended firmware interface (EFI) on an itanium-based computer. Compared with the primary startup record (MBR) Partitioning Method, GPT has more advantages because it allows each disk to have up to 128 partitions and supports a volume size of up to 18 Gigabit bytes, the par

NBSP;MBR and GPT are two different par
MBR partitioning and GPT partitioning
There are two types of partitioned tables: MBR and GPT. MBR is the traditional format of the partition table, in the hard disk capacity of today, the MBR inherent some deficiencies, resulting in MBR partition table can not very good management of large-capacity hard drives; GPT is a new generation of partitioned tables, much
was later realized that the pit was caused by a GPT partition on the hard drive. So why did I let Ubuntu automatically partition it into a GPT partition? It also blames this HP's working machine is very exotic, it supports the legacy BIOS, also supports EFI, when the original WinXP exists, it uses of course the MBR partition (MSDOS partition), So the installation of Ubuntu is the use of the MBR partition,
Tags: BSP UI space UUID ROC technology span SaveMSDOS (MBR) and gpt--early Linux systems used MBR to process boot and partition tables, usually placed in the first sector of the disk (512 bytes), but the MBR partition can only crawl 2TB of capacity, and so on, the new partition format GPT resulting
