GPT and MBR are hard drive partitions that always appear when installing Windows. Maybe you have found a case on the latest computer / laptop why can't install Windows with the "Windows can not be installed on this disk." The selected disk is the GPT partition style. "The meaning of the message is having to use the MBR partition type because the current hard disk is GPT. In order to be installed Windows will have to change or convert to MBR type.
There are several ways to convert GPT to MBR, but the most recommended and easy to do using EaseUS Partition Master. This application can be downloaded through the official website of EaseUS then select Partition Manager. One of the excellent tools of EaseUS Partition Master is Convert GPT to MBR
Well before the discussion phase How to Convert GPT Harddisk to MBR you should first understand the typing and differences of the two types of partitions, here are the reviews.
Understanding GPT Hard Drive
Guide Partition Table (GPT) is a new partition standard on computers that support UEFI BIOS. This type of hard disk has been applied to the latest laptops that use Windows 10. The difference with MBR is that the number of partitions is unlimited even though the maximum is only 128 partitions while the MBR is a maximum of 4 partitions.
In the GPT hard drive type, the partition table layout is defined using the Global Unique Identifier. The presence of GPT is expected to cover the shortcomings of the MBR, so that the GPT also has many advantages compared to the MBR. This is the advantage:
1. Supports storage media or hard drives up to 9 ZB (Zettabyte). Zettabyte is 3 levels above Terabyte (TB). On top of TB there are Petabyte (PB), Exabyte (EB), Zettabyte (ZB), and Yottabyte (YB)
2. Can support up to 128 Primary Partitions
3. File system information and operating system location are stored in more than one location, so that if the main is damaged, the system can still run normally using other backups.
MBR Harddisk Testing
Master Boot Rercord (MBR) is a type of old standard hard disk partition that is still used by many computer users in the world. In the MBR system it is only limited to using 4 primary partitions on your hard drive. The fourth partition is the main partition on the hard disk, the rest will include extended-partitions that can be made sub-partitions in it. MBR itself uses a 32-bit system to record partitions, of course, each partition of the MBR will be limited, the maximum can only reach 2 Terabytes in size.
In the MBR there is a partition table consisting of:
1. Primary Partition
The main partition type on the hard drive. This partition processes the boot to enter the operating system. In each hard drive, the number of primary partitions is limited to 4.
2. Extended Partition
Is part of the main partition whose function is to duplicate logical partitions. The amount is only 1 on each hard drive.
3. Logical Partition
This partition cannot run the boot process, but can only store data. The number on each hard drive is unlimited. This logical partition is in an extended partition. So, this logical partition rests on the extended partition.
GPT is present to cover up the flaws in the MBR partition type, if the above has been explained using the GPT partition type, the following are the shortcomings of the MBR:
1. Can only support a maximum 2 TB hard drive
2. Can only support for making a maximum of 4 Primary Partitions
3. If you want to make more partitions, 1 primary partition must be sacrificed into an extended partition so that you can create several logical partitions
4. Information about the location of the file system and operating system partition is only stored in the first sector on the hard drive, so that if it is lost or corrupted the operating system will be damaged.
How to Change GPT Harddrive to MBR With EaseUS Partition Master
1. Download https://www.easeus.com/partition-manager/epm-free.html
2. Then install it to your computer and run it
3. Please pay attention to the picture below, which is a GPT hard drive on Disk 4. Please click on the Disk (remember don't drive it ...)
4. In the Operations menu option select Convert GPT to MBR
