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
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 t
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
Use gdisk to adjust the size of the gpt/ext4 partition and gdiskgptext4 Partition
Host: CentOS release 6.4 (Final)
Purpose: GB from the/home partition to create a new partition/vm

First figure out what is MBR partition table, what is GPT disk? (1) MBR and GPT are two different disk types, the main difference is the different partition structure and partitioning method. GPT is a new type of hard drive that has emerged in recent years. (2)
How do I change a GPT partition to an MBR partition?"Because the laptop hard disk partition table is GPT and you can't install the boot system. The need to convert to an MBR partition can also be successfully installed. “The probl
USB disk Boot installation RHEL5.8 prompt: Boot partition is located in a GPT partition scheme error prompt, English: "Your boot partition is on a disk using GPT partitioning scheme but this Machin E cannot boot using GPT, unable
When the USB flash drive is started and rhel5.8 is installed, the following error message is displayed: "your boot partition is on a disk using GPT partitioning scheme but this machine cannot boot using GPT", unable to continue the installation.
Cause of error: the hard disk format was changed to
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. NBSP;MBR and
The GPT partition under Linux, which is another partition for MBR partitioning, has many advantages:(1) Almost break the limit of the number of partitions.Up to 128 primary partitions can be supported in a GPT partitioned table.(2) The capacity of a single partition is almos
How to solve the problem of GPT partition table during linux installation I. problem: if Windows, VMware, and MacOS have been installed on the server before, you may encounter a GPT partition table used for your boot partition, but this machine does not support starting with
Before converting, let's take a look at what is GPT and why do you want to convert it?
Gpt:guid Partition table (GUID partition table disk partition style supports maximum volume of EB (exabytes) and up to 128 partitions per disk)
We can go to "Disk Management", right click on the disk model below, see the
As we all know, I cannot use common Fdisk commands when the disk partition in linux is larger than 2 TB. Is there no way to use large-capacity disks in linux? Answer: No. In linux, we can convert a large-capacity disk to the GPT format. As the GPT format disk is equivalent to the four partitions in the original MBR disk, we all know that in linux, when the disk
primary partition location.Logical partitioning: Logical partitions are created based on extended partitions. Linux supports a maximum of 63 IDE partitions and 15 SCSI partitions.Seven, GPT (GUID Partition table, globally unique identity partition table)GPT is a newer parti
How to solve the problem of GPT Partition Table during linux installation I. Problem: If Windows, VMware, and Mac OS have been installed on the server before,You may encounter the problem that "your boot partition uses GPT partition tables, but this machine does not support
Nowadays, hard disks are very cheap and the capacity is N large. common dos partition tables cannot meet the needs of large hard disks. The sin of a dos partition table is that 1. only a limited number of partitions are supported. for historical reasons, only 64 K (4x16 k) is reserved for the primary partition, that is, four primary partitions; 384 k (24x16 k) is
In linux, we can convert a large-capacity disk to the GPT format. Because the GPT format disk is equivalent to the 4*16 bytes of the four partition tables originally reserved in the MBR disk, only the first 16 bytes are reserved. Others are similar to extended partitions, the real partition table is 512 bytes later, so
Nowadays, hard disks are very cheap and the capacity is N Large. Common dos partition tables cannot meet the needs of large hard disks.
Dos partition table:
1. Only a limited number of partitions are supported.
For historical reasons, only 64 K (4x16 k) is reserved for the primary partition, that is, 4 primary partitions; 384 k (24x16 k) is reserved for the logic
Most of the computers preloaded with WIN8 are in the new version of the UEFI firmware + GPT format disk, which has the advantage of enabling additional features such as safe booting, and support for more hard disk partitions and larger partition capacity. Here we describe how to create an OEM partition on a GPT hard dr
