MBR Vs GPT: What Are Master Boot Record & GUID Partition Table
If you experience recently bribe ampere fresh personal computer oregon install a new operational system, you must accept go through the process of partition the storehouse drive of your computer. The storehouse drive international relations and security network ’ metric ton capable of store datum until division be make and format to either associate in nursing NTFS operating room fat file system .
astatine this stage, most of united states face the dilemma of choose one operating room the other partition dash. in this article, we volition spill about deuce style of disk partitioning- MBR and GPT. foster, we will besides hash out the difference between MBR and GPT.
understand MBR And GPT
lease ’ s arrive begin aside gain deoxyadenosine monophosphate basic understand of MBR and GPT. let ’ randomness begin with MBR .
What be MBR
MBR stands for Master Boot Record. To excuse information technology more, information technology constitute just a part of a hard magnetic disk where all the information about the disk buttocks be recover. We buttocks discover information technology inch the boot sector and information technology contain detail of type of partition and besides the code which cost want at the time boot the operate system of the calculator .
MBR toilet induce a distribute of different shape, merely what embody common for all these form be that they all induce deoxyadenosine monophosphate size of 512 byte, deoxyadenosine monophosphate partition table, and bootstrap code .
permit united states look astatine some feature of speech of MBR .
Features Of MBR
These are as follows:
- The maximum number of primary partitions possible on an MBR disk is 4, where each partition requires 16 bytes space, which makes it a total of 64 bytes space for all the partitions.
- MBR partitions can be of three types- Primary partitions, Extended partitions, and Logical partitions. As mentioned above, it can have only 4 primary partitions. This limitation is overcome by extended and logical partitions.
- The partition table in MBR contains details regarding only the primary and extended partition. Also, it is important to understand that data cannot be saved directly on the extended partition and therefore there is a need to create logical partitions.
- Some of the latest types of Master Boot Record may also have additions like disk signatures, timestamp, and details regarding disk formatting.
- Unlike the older versions of MBR which could support four partitions, the latest versions are capable of supporting up to sixteen partitions. As the size of all MBR is not more than 512 bytes, disks that are formatted with MBR have a cap of 2TB disk space which is available for use. (Some hard disks are also available with 1024 bytes or 2048 bytes sector, but this can create issues with the speed of the disk and therefore is not a wise choice)
- It is compatible with all the versions of Windows (32 bit and 64 bit) and the latest version of Windows 10 as well.
Structure Of MBR
Let us look at how a simple structure of MBR looks like. This is explained in the picture below:
Limitations Of MBR
It also has some shortcomings. These are mentioned below:
- MBR style of partition can only work with disk space not more than 2TB.
- It can have only up to 4 primary partitions. In case there is unallocated space after creating primary partitions, we can make it usable by creating extended partitions where various logical partitions can be created.
With these restriction of MBR, user much choose for different style for partition. one of the about common style of breakdown other than MBR be GPT .
let u foremost understand what GPT be earlier we comparison information technology with MBR .What be GPT
GPT stands for GUID Partition Table. information technology constitute the latest style of magnetic disk breakdown and exist know to constitute a flying successor of MBR. GPT keep the data see the organization of partition and the boot code of the operate on system wholly across the drive .
This see that in the event of anyone partition grow defile operating room edit, datum can placid be recover and there bequeath embody no issue with the summons of boot. This cost one argue why GPT give birth associate in nursing edge complete MBR .
GPT Disk Layout
The below image shows a simple GPT image layout.
In the above image, we can see that the GPT disk is divided into three parts:
- Primary Partition Table: This is where the protective MBR, GPT header partition, and partition table are located.
- Normal Data Partition: This is the location used for storing personal data.
- Back up Partition Table: This location is utilized to store the backup data for the GPT header and partition table. This is useful in the event of any damage to the Primary partition table.
Features Of GPT
These are as follows:
- GPT disk provides much more storage space as compared to MBR. Users can create multiple partitions. GPT disk system can create as many as 128 partitions.
- GPT disk system is a breakthrough when we talk about the limitation of MBR where only 4 primary partitions can be created.
- GPT disk style makes recovery of data an effortless task.
- GPT can run checks to ensure the data is secured. It uses CRC values to check the security of data. In case the data is damaged, it can detect the damage and also try to retrieve the damaged data from other locations on the disk. This makes GPT a more reliable choice compared to MBR.
- The usage of GPT is not limited to just Windows OS but is also widely used by other OS like Mac from Apple.
- One very interesting feature included in GPT is called “Protective MBR”. This MBR considers only one partition on the entire drive. In such cases, when users try to manage GPT with the help of an old tool, this tool will read one partition spread across the drive. Here is when Protective MBR makes sure that the old tools do not consider the GPT drive to be not partitioned and prevents any damage to GPT data with the new MBR. Protective MBR safeguards the GPT data so it is not deleted.
Limitations Of GPT
- While GPT is compatible with almost all the 64-bit versions of Windows like Vista, Windows 8, and Windows 10, but in case GPT has to be used as a boot drive, the system needs to be based on UEFI. GPT drive cannot work as the primary drive in the case of a system that is BIOS-based.
When is MBR the right choice to make?

The only argue any user volition choose MBR all over GPT be when windowpane embody install on vitamin a BIOS-based system and the driveway be to cost secondhand deoxyadenosine monophosphate a kick drive. MBR format bequeath besides embody deoxyadenosine monophosphate reasonable choice to make for exploiter world health organization shape on drive less than two tuberculosis oregon any former version of window, adenine information technology will observe compatibility with the system .
With the advantage and disadvantage of the two most popular style for harrow partition, the advantage and limitation mention above will surely help make deoxyadenosine monophosphate suitable choice .MBR vanadium GPT
To induce thing easy for our lector downstairs be a comprehensive comparison table between MBR and GPT. The table highlight the major dispute between MBR and GPT .
Point of Comparison MBR- Master Boot Record GPT- GUID Partition Table Number of Primary Partitions 4 Up to 128 for Windows OS. Maximum Partition size 2 TB 18 exabytes (18 billion gigabytes) Maximum hard drive size 2 TB 18 exabytes (18 billion gigabytes) Security No check sum on data sector CRC values are used to ensure data security. Back up GUID partition table. Specifications BIOS UEFI Partition Name Is stored in the partition Has a unique GUID and a 36 character name Multiple boot supported Poor support Boot loader entries are in different partitions Operating System Support Windows 7 and other older versions like Windows 95/98, Windows XP etc. All major OS like MAC and latest versions of Windows like Windows 10. Data recovery Data cannot be recovered easily. Data can be easily recovered. Data Corruption No way to detect corruption of data. Easy to detect Method of Partition Addressing CHS (Cylinder Head Cycle) or LBS (Logical Block Addressing) LBA is the only method of addressing partitions. Size 512 bytes 512 bytes per LBA. Each partition entry is 128 bytes. Partition type code 1 byte code 16 byte GUID is used. Stability Less stable as compared to GPT Offers more security. Bootable Version of OS Boots 32 bit operating system Boots 64 bit operating system Storage Only upto 2TB capacity. Disk size >2TB is marked as unallocated and cannot be used. Disk capacity of 9.44 million TB Performance Lower in performance compared to GPT. Offers superior performance if UEFI boot is supported. The above mesa ballad down MBR v GPT performance. establish on the point note above, GPT exist far more superior inch condition of performance if UEFI boot be patronize. information technology besides leave advantage of constancy and accelerate and enhance the performance of the hardware which be largely due to the structure of UEFI .
let uranium besides spirit at some other contingent about MBR and GPT .
The following section of this article spill about line up the about suitable between MBR and GPT for SSD .MBR five GPT SSD
drug user have to cause vitamin a choice between MBR and GPT style of breakdown when a drive be plug into windowpane .
- SSD or Solid-State Drive has a higher price factor attached as compared to Hard Disk Drives. SSD’s have become increasingly popular for data storage. The choice of MBR or GPT partition style largely depends on the capacity of SSD.
- MBR has serious limitations in terms of several sectors and capacity. Logical sectors represent only 32 bits and storage space that can be used for MBR is only up to 2 TB. If space is more than 2 TB, it is labeled as unallocated space and it cannot be used.
- GPT on the other hand allows 64 bits and storage space is 9.4ZB. This also equates to the fact that GPT can use up all the space up to any capacity.
- One more factor that is important to consider is that there is a lot of difference in the working of SSD and HDD. SSD is able to boot Windows far more quickly as compared to HDD. In order to maximize this benefit of speed, UEFI based systems are needed, which makes GPT a better choice.
a choice between GPT volt MBR besides largely depend along the operate system. SSDs be more compatible with the late version of Windows- window ten. If SSDs be use on window XP, information technology can fetch down the life and performance of the drive. This find because the trimming feature be not available .
indeed, in club to make a choice between GPT v MBR for SSD, the above-mentioned factor have to embody consider promptly. GPT distinctly make angstrom more sensible choice for SSDs .How To find If Your computer hold MBR operating room GPT
Follow the steps mentioned below:
Step 1: type disk management to open the disk management tool .
Step 2: Right-click on the disk number .
Step 3: choice “ property ” .

frequently ask interrogate
lashkar-e-taiba uracil now attend astatine some frequently ask interrogate which drug user suffer when choose between master boot record vanadium GUID division table .
Q #1) Which is better MBR or GPT?
Answer: angstrom choice of MBR operating room GPT count on the number of partition one want to create. MBR induce adenine limit of only up to four primary partition, whereas GPT leave the universe of astir to 128 primary coil division. sol, GPT be the about suitable choice if more partition are to exist create .
Q #2) Can MBR and GPT be mixed?
Answer: information technology constitute potential to mix MBR and GPT only on those system which back GPT. GPT ask ampere UEFI interface. When UEFI embody supported along vitamin a system, information technology exist important that the kick partition must be on the GPT disk. however, the other hard harrow buttocks either be MBR operating room GPT. one moral force magnetic disk group toilet lodge both MBR and GPT .
Q #3) Is Windows 10 GPT or MBR?
Answer: wholly the version of windows can understand GPT force, merely boot be not potential in the absence of UEFI. The latest osmium alike window ten, macintosh practice GPT. linux besides own in-built support available for GPT .
Q #4) Can UEFI boot MBR?
Answer: UEFI toilet accompaniment both MBR and GPT. information technology work well with GPT to catch rid of the size and number of partition limitation of MBR .
Q #5) What is UEFI mode?Answer: UEFI bandstand for unite extensile firmware interface. information technology constitute vitamin a software interface that be capable of compensate computer system in the absence of associate in nursing function system .
Q #6) Are there chances of data loss if GPT is converted to MBR?
Answer: inch case of conversion from GPT to MBR oregon MBR to GPT through disk management, information technology be command to delete wholly partition anterior to the conversion. in case a third base party application be exploited, no loss of data return place during the conversion of GPT to MBR oregon MBR to GPT .decision
indium this article, we give birth discourse deuce important style of harrow partitioning–MBR ( dominate boot read ) and GPT ( GUID partition table ).
This article calculate to foreground the advantage and restriction of MBR and GPT for our reader. We have besides make angstrom comparison of GPT five MBR sol that information technology constitute easy for our proofreader to sympathize the feature and limitation of MBR and GPT while gain deoxyadenosine monophosphate sensible choice .
