What are the advantages of UEFI over BIOS?

Benefits of UEFI boot mode over Legacy BIOS boot mode include:

• Support for hard drive partitions larger than 2 Tbytes.
• Support for more than four partitions on a drive.
• Fast booting.
• Efficient power and system management.
• Robust reliability and fault management.

Is UEFI faster than BIOS?

UEFI can run in 32-bit or 64-bit mode and has more addressable address space than BIOS, which means your boot process is faster. ... UEFI is essentially a tiny operating system that runs on top of the PC's firmware, and it can do a lot more than a BIOS.

Both of these interfaces are used at the startup of the computer to initialize the hardware components and start the operating system which is stored on the hard drive ...

What are the disadvantages of UEFI?

The biggest problem with UEFI is hardware and software support. In order for it to work properly, the hardware and operating system must both support the appropriate specification. This isn't as much of a challenge with the current Windows or macOS but older operating systems such as Windows XP do not support it.

Can I change BIOS to UEFI?
