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

Large hard disk and WIN8 system, let us from the traditional bios+mbr mode upgrade to UEFI+GPT mode, now buy mainstream computers, are pre-installed WIN8 system, in order to better support 2TB hard disk, faster start Win8, pre-installed systems have taken the GPT partition format, and the motherboard BIOS supports UEFI boot. 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,

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.

The previous section implements the extraction of the main GPT header, which continues to extract the entire GPT data, and merges the GPT partition table and MBR partition table into a single module, so that the master function (or the consumer) does not need to care about the partition table type of the disk: it is too low, and does not need too much care.Contin

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

drive of the installed operating system. The so-called bootloader is a small piece of code that is used to load larger loaders on other partitions on the drive. If you have installed the initial information for the Windows,windows boot loader in this area-if the MBR information is overwritten causing Windows to not start, you will need to use the MBR Repair feature of Windows to get it back to normal. If you have Linux installed, it will usually be t

special boot sector that exists in the start part of the drive. This sector contains logical partition information for the boot loader and drive of the installed operating system. The so-called bootloader is a small piece of code that is used to load larger loaders on other partitions on the drive. If you have installed the initial information for the Windows,windows boot loader in this area-if the MBR information is overwritten causing Windows to not start, you will need to use the MBR

the WINRE environment:1, if the use of Win7, restart the computer. When the brand logo appears, press F8, and then select "Repair Computer" in the "Advanced startup Options" that appear.Figure 2:windows7 Advanced Boot OptionsThen, if a list of select repair operating systems appears, select "Command Prompt".2, if you are using Win8, enter Win8 first, then open the Right Charm menu, click "Settings"--"Chang

HDDWait.USB HDDUSB flash drive, clickCentOSThen you can start CentOS. It is successful here.Experience It took me a long time to install this dual system, but I also learned a lot, such as the difference between UEFI and traditional Legacy, the working principle of UEFI, and the role of PE, the final file is not lost, which is a value. The following is a summary.1. UEFI + GPT dual system installation is really troublesome2. Microsoft's monopoly menta

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, re
