GPT
GPT is the newer of the two. GPT is closely associated with UEFI, the firmware solution modernizing the old alternative, BIOS. GUID Partition Table assigns every partition on your drive a globally unique identifier (GUID) which is a 128-bit number that identifies only your hardware (a 128-bit integer has a maximum value of 1.7 x 10^39---a phenomenally large number).
GPT drives suffer few of the limitations of an MBR drive. GPT drives can be vastly larger than their MBR counterparts (with the right settings, a theoretical 256TB drive would work). On a Windows system, GPT drives can have up lớn 128 different partitions without using an extended partition. Other systems allow even more.
One addition major difference is in GPT drives store boot data. Unlike the MBR drive, the GPT drive stores multiple copies of the boot data across several partitions, making recovery much easier.
Compatibility
Not all versions of Windows can boot from a GPT partitioned drive, with many requiring a UEFI-based system.
64-bit Windows 10, 8/8.1, 7, & Vista all require a UEFI-based system khổng lồ boot from a GPT drive. 32-bit Windows 10 & 8/8.1 require a UEFI-based system to lớn boot from a GPT drive. 32-bit Windows 7 & Vista cannot boot from a GPT drive. All mentioned Windows versions can read from và write khổng lồ a GPT drive.Other operating systems also use GPT systems. For instance, táo now uses GPT rather than its táo Partition Table (APT). Furthermore, Linux has built-in support for GPT drives.
How to Convert MBR khổng lồ GPT
As we have seen, GPT is the more modern partition table type, offering better recovery and more overall versatility. For a long time, converting from an MBR drive to a GPT drive meant wiping the drive as part of the conversion process. But now there are two tools you can use to safely convert your drive without any data loss.
Note: There is no going back unless you wipe your drive. MBR lớn GPT is a one-way transformation. Please also remember there is a small chance your drive will cease to function after the conversion. While this is an extremely small chance, heckorea.com và I accept no responsibility for your hardware if you continue with this tutorial after this warning. In this, the validation step in the upcoming tutorial is very important.
There is one final kiểm tra to make before converting your disk. Does your hardware tư vấn have UEFI-support? If not, your hardware won"t register the drive following conversion and, if converting a bootable drive, you will not have access to your operating system.
MBR2GPT
Microsoft"s MBR2GPT tool is already on your system as part of the Windows 10 Creators Update.
The tool primarily caters to lớn sysadmins who have khổng lồ deploy Windows 10 installations on a large number of computers. However, you can use it to switch your MBR drive to lớn GPT with minimal hassle. Here"s how.
First, check your disk number. Complete a Start menu search for Computer Management and select the best match. Select Disk Management and locate the disk you want lớn convert, noting the disk number. Right-click the disk number, select Properties and open the Volume kiểm tra the current partition type is MBR. Press Windows + X, then select Command Prompt (Admin) from the menu. If Command Prompt (Admin) is no longer an option, complete a Start menu search for Command Prompt, then right-click and select Run as Administrator. Now, validate the disk you want khổng lồ convert. Type mbr2gpt /validate /disk:
Type mbr2gpt /convert /disk:
EaseUS Partition Software
The second option for converting MBR khổng lồ GPT is lớn use EaseUS Partition Master Professional. Honestly, this is the easier of the two conversion options, using a similar UI khổng lồ the Windows Disk Management screen. However, EaseUS Partition Software has several additional options, not least of which is the Convert MBR to lớn GPT tool.On the other hand, EaseUS Partition Master Professional will mix you back $39.95, while the Windows integrated MBR2GPT tool is already part of your operating system.
open EaseUS Partition Master and wait for your drives to load. Locate the drive you want to convert. Select the disk, right-click, & select Convert MBR khổng lồ GPT. Press the Apply button on the toolbar. Once you hit apply, your system will reboot. You"ll arrive at an EaseUS Partition Master operation screen that shows the conversion process taking place.
You need lớn change your firmware khổng lồ boot to UEFI mode. After your system restart, press your BIOS/UEFI entry key. Change the boot type lớn UEFI mode, as opposed khổng lồ Legacy Mode or other equivalents.
In my opinion, EaseUS Partition Master makes the process easier but is slightly slower than its free Microsoft counterpart.
MBR khổng lồ GPT Conversion Complete!
You have now converted your old MBR drive into a GPT drive, granting additional control over how you use your drive. If your system fails khổng lồ boot after conversion, remember lớn head khổng lồ your BIOS/UEFI settings and make sure the UEFI boot option is turned on.
