About UEFI Boot

Why do so many people want to create a UEFI boot USB? In order to create a UEFI bootable USB successfully, it is necessary to figure out the following 2 questions first.

What Is UEFI

UEFI (Unified Extensible Firmware Interface) is known as a motherboard firmware interface for computers. It serves as a “middleman” between your computer’s firmware and the operating system. With UEFI boot mode, your computer can initialize the hardware components and boot the OS stored on the hard disk.

In recent years, UEFI boot mode seems to be the successor to the BIOS. More and more users tend to boot their computer in UEFI mode. This is because the UEFI mode breaks many limitations of BIOS mode, including the restrictions on the size of hard drive, booting process, number of partitions, and security.

In a word, UEFI boasts more advanced features compared with BIOS. Here we summarize them as follows:

• UEFI allows users to handle a storage device that is larger than 2TB, while the old legacy BIOS cannot handle so large d
• With UEFI boot mode, you can create more than 4 primary partitions on a GPT disk.
• UEFI supports secure startup. It is capable of checking the validity of the operating system to prevent malware from tampering the startup process.
• UEFI firmware supports various optimization and enhancement, which can help your system boot more quickly than it could before.
• UEFI supports both 32-bit and 64-bit architectures, which helps the computer use more RAM to handle a more complicated process than BIOS.
• Under the UEFI mode, the computer supports networking function that can help remote troubleshooting and UEFI configuration.
• UEFI has much more setup menus and simpler graphical user interface than legacy BIOS.

What Support UEFI Boot Mode

UEFI has lots of advantages over BIOS, but not all computers and devices are supported. In order to boot from USB in UEFI mode successfully, the hardware on your hard disk must support UEFI. One of the most important things is to make sure that your system disk is GPT form. If not, you have to convert MBR to GPT disk first.

If your hardware doesn’t support the UEFI firmware, you need to purchase a new one that supports and includes UEFI.

Now, you may have an overall understanding of UEFI boot mode. Let’s see how to create a Windows 10 UEFI boot stick. Please keep reading the following part carefully.
