In the process Learn How to reinstall Windows or create USB Boot, you will often be the blog site mentioned the phrase Legacy and UEFI, GPT and MBR. So what is it and how it works on your computer? Should use UEFI and Legacy or MBR and GPT?
If you still don’t understand exactly how the Legacy and UEFI BIOS and the differences between them as to how between MBR and GPT? In this article, I will fully back the General information on this phrase as well as share personal experiences to help you can answer this questions is the best way.
Learn Legacy BIOS and UEFI?
The standard concept of the Legacy BIOS
Legacy BIOS or be referred to as the BIOS (Basic Input Output is System) was born in 1975. It is a software that is stored on your computer’s motherboard chips, the main function of this software is to guide running the hardware components to boot the OS on the computer.
When you open your computer, the BIOS start operation to check the hardware like Ram, the processor first, followed by the peripherals such as mouse, keyboard, printer, … then boot option, the order from CD-ROM drive , Hard disks, Lan, …
Standard concept about UEFI
UEFI was born in 2005 and the full name is Unified Extensible Firmware Inter, it also is a software used to guide the hardware after the switch to help launch the computer operating system, however the UEFI is designed to address the weaknesses of the Legacy BIOS and now it is being used widely and will replace Legacy BIOS in the future.
In common between the Legacy BIOS and UEFI
Basically both the Legacy BIOS and UEFI is the software interface to test the device on computer and help for computer operation, it acts as a translator between your hardware and operating system to help computers launch.
When you turn on the computer, both UEFI and Legacy will check and guide the hardware of the computer to help the beginner slopes of the computer can run the operating system contained on the hard drive.
Other points between the Legacy BIOS and UEFI
|Standard Of The Legacy BIOS||UEFI Standard|
Computer supports UEFI or Legacy BIOS?
1. Access the BIOS your computer PC or Laptop
Step 1: You need to use the shortcut keys on the keyboard to access the computer’s BIOS
Step 2: In the view of the BIOS, go to the Boot Menucard. If you see the lines as UEFI , or Security Boot when your computer that has UEFI support, if not found, the computer is not supported.
2. Use third software-HWiNFO
Step 1: You can download this software in this link: HWiNFO 32 bit & 64 bit HWiNFO
Step 2: Proceed to extract the downloaded files, then right click on the .exe file to selectRun As Administrator.
Step 3: Click RUN to run the software, will have two interfaces appear, you take off the window System Summary.
Now, let’s chý to line the UEFI Boot on software. If the line appears “Present”, meaning the computer mode support UEFI.
In case you find the line “Not Present” then your computer is operating in Legacy mode, the BIOS and does not support UEFI. However, you need to check out one step further to see if the computer has support for UEFI or not for sure yet “Not Present” says that the computer does not support UEFI.
On the left side of the interface software HWiNFO, click on the Mainboard >> line Search line UEFI BIOS as below.
If you see the words “Capable”, IE the computer you have supports UEFI, also if the line appears “Not Capable” then your computer does not support.
3. Using the System Information program
Step 1: Open the Run dialog from the computer, can quickly open by the keyboard shortcut Windows + R .
Step 2: Proceed to enter the command line below and then press Enter.
The UI System Information appears, you look to the line BIOS Mode, you will identify the computers that are using Legacy or UEFI.
4. Use the DiskPart program
Step 1: Open the Run dialog box, type in “diskpart” then press Enter.
Step 2: Quickly enter the next command “list disk” and hit Enter.
Meanwhile, the list of hard drives on the hard drive will appear. If in the column marked GPT “*” means that hard drives are running in standard of GPT, also not marked with “*“, then it is running in the MBR. From there, you can get to know your computer has support for Legacy BIOS or UEFI.
However, this alone is not advisable to use because it does not check correctly if the computer has support for UEFI. This way only fit to check the hard drives that are using the standard MBR or GPT .
Learn about MBR and GPT?
When initialized in new disk on the Windows operating system, you will be asked in the choice between the standard MBR and GPT. Although the MBR has a higher compatibility compared to the GPT but it has quite a lot of restrictions should in future standard will replace GPT MBR. Moreover, increasingly are many other operating systems, GPT support not only Windows but also macOS, and Linux are all supported.
MBR and GPT are both on the hard drive’s standard rules how the import data, sort as well as partition of the hard drive.
Details about MBR
Details on GPT
Comparison between the standard MBR and GPT
|Standard MBR||GPT Standard|
|Supports a maximum of 2 TB
Lets just create 4 partitions
Less secure than GPT
Can be used on a computer with both standard BIOS or UEFI
Only supports Windows 32 bit
|Supports up to 1 TB rate
Allows to create up to 128 partitions
More secure because of the having support create multiple backups of data
Only supports the standard computer using UEFI
Support for Windows 64 bit from Windows 7, Windows 8 to have more support 32 bit.
