See http://www.youtube.com/watch?v=iyx8LUHshsc for BIOS/MBR booting.
See lothaz0r's comparison (http://www.youtube.com/watch?v=dQIE5tV2LAs) with 2x Kingston HyperX 3K SSDs in RAID 0 on Windows 8 with larger effect if GPT is used along with UEFI.
UEFI/GPT (left) leads, BIOS/MBR (right) trails.
Per Adobe Premiere Pro CC 2015's timecode precision at 30 FPS, 1 frame equals to ~33 milliseconds.
The rig is running Windows 10 Pro 64-bit with all updates installed on a Samsung 840 EVO 120GB SSD. The system has been completely optimized using tweaks from Ultimate Windows Tweaker 4.0 and from TweakGuides Tweaking Companion.
Both boot and storage drive have been converted to use GUID Partition Table without data loss using AOMEI Partition Assistant Professional Edition. Boot mode has been set to UEFI Only in Gigabyte's UEFI DualBIOS setup before conversion.
Storage drive has three partitions merged into one using the same software mentioned above.
Why GPT? Because the older MBR is unable to address storage media capacities higher than 2,199 GB (4,294,967,296 x 512 bytes).
The video is edited on Adobe Premiere Pro CC 2015 and is then exported as a mathematically lossless video using MagicYUV.
Captured at 3840x2160 resolution using Samsung Galaxy Note 3. Video stabilization is not available at 3840x2160, however, available at 1920x1080.
To watch this in 3840x2160 resolution, click Settings and select Original in Quality selection. You need a really fast Internet connection and a monitor that can display up to 3840x2160.

01:18 What is UEFI
02:14 What's the difference between UEFI vs BIOS
03:01 How to interconvert MBR and GPT
04:19 How to set UEFI or BIOS boot mode
For more details, refer to: https://bit.ly/3W9Gfbq
What is BIOS?
BIOS stands for Basic Input/Output System. It is stored on an EPROM (Erasable Programmable Read-Only Memory), allowing the manufacturer to push out updates easily. The BIOS must run in 16-bit processor mode and has 1 MB of space to execute it.
The BIOS goes through a POST (Power-On Self Test) to check if your hardware configuration is ready for normal work, and after that, the BIOS looks for a Master Boot Record (MBR) to launch the bootloader to eventually launch Windows. It's how the MBR works that constraints the BIOS cannot recognize the hard drives larger than 2TB.
You can access BIOS during the initial phases of the boot procedure by pressing del, F2, or F10.
What is UEFI?
UEFI stands for Unified Extensible Firmware Interface. It does the same job as a BIOS, but with one basic difference: it stores all data about initialization and startup in a .efi file, instead of storing it on the firmware. This .efi file is stored on a special partition called EFI System Partition (ESP) on the hard disk. UEFI has a graphic and slicker interface, supports over 2 TB hard drives.
When you deploy Windows to a UEFI-based device, you must format the hard drive that includes the Windows partition by using a GUID partition table (GPT) file system.
What's the Difference Between UEFI and BIOS, Which is better?
UEFI supports drive sizes up to 9 zettabytes, whereas BIOS only supports 2.2 terabytes.
UEFI provides faster boot time.
UEFI has discrete driver support, while BIOS has drive support stored in its ROM, so updating BIOS firmware is a bit difficult.
UEFI offers security like "Secure Boot", which prevents the computer from booting from unauthorized/unsigned applications.
UEFI runs in 32bit or 64bit mode, whereas BIOS runs in 16bit mode. So UEFI is able to provide a GUI (navigation with the mouse) as opposed to BIOS which allows navigation only using the keyboard.
How to Interconvert MBR and GPT
You can interconvert MBR and GPT with EaseUS Partition Master without data loss.
Step 1. Download and launch EaseUS Partition Master on your Windows computer.
Step 2. Right-click the MBR disk that you want to convert and choose "Convert to GPT" or "Convert to MBR".
Step 3. After that, find and click the "Execute 1 Operation" button on the toolbar and choose "Apply" to start the conversion.
How to Set UEFI or Legacy BIOS Boot Mode
Step 1. Restart PC and press F2, F8, F12, Del to enter the BIOS boot menu.
Step 2. From the BIOS Main Menu screen, select Boot.
Step 3. From the Boot screen, select UEFI/BIOS Boot Mode, and press Enter.
Step 4. Save the changes and exit BIOS, reboot the PC from the GPT disk.

0:20 To start with, I will first look at what the BIOS is. Essentially, the BIOS is a microchip found on the motherboard. BIOS is essentially what is referred to as firmware. Firmware contains basic low-level software that controls the hardware in the device it is installed in. In the case of computers, the BIOS contains basic input and output software which is used to communicate with hardware. When the computer is first switched on, the BIOS software is used to test the hardware within and connected to the computer. Once complete, the software in the BIOS is used to access the hardware.
BIOS was first created in 1975 by IBM. It was later reverse engineered to be used in non-IBM computers. Nowadays there are three companies that make the majority of BIOS chips and IBM is not one of them. I will now have a closer look at what happens when a computer starts up, to give you a better understanding of how the BIOS works and what it does.
Powering Up PC
1:20 To start with, I will first look at what happens when the power button is pressed on a computer. When the power button is pressed, a circuit is closed which causes a test to be preformed of the computer’s power supply. If there is a problem with the power supply, usually there will be no power output at all and the computer will not start.
If the power supply test is o.k., the power supply will send power to the CPU. Now the CPU has powered up, it will start executing instructions, because that is what a CPU was designed to do. In order to do this, it needs software and this is where the BIOS comes into play.
Load BIOS Software
1:56 The BIOS is essentially a microchip on the motherboard. This is also often referred to as firmware. Older BIOS chips use Electrically Erasable Programming Read-Only memory called EEPROM, whereas modern BIOS uses flash RAM. This allows the code in the BIOS to be updated, but the code on the BIOS cannot be directly run from the chip itself.
In order for the CPU to execute the code in the BIOS, the code in the BIOS is copied to the memory inside the computer. So essentially this means that in order for a computer to start, it requires memory. If you attempt to power up a computer that does not have memory installed, the motherboard will emit a number of beeps to alert you that there is a problem.
Once the BIOS code has been copied to memory, the CPU can now start executing the code. So essentially what happens is this. When you press the power button, the code in the BIOS is copied to memory and then is executed by the CPU. The next question is, what does this code do?
POST Tests
2:57 The next step is that the BIOS performs a number of tests. These tests are referred to as POST or power- on self-test. These are a number of quick tests to check everything appears to be working. There may still be hardware faults, but the POST tests should pick up any basic problems.
POST tests include but are not limited to, checking the memory installed. This is a quick check to see if everything appears to be working correctly. There are a number of memory testing software tools available that can do more advanced tests if required.
Tests also include checks of any attached storage devices. This is basic testing to ensure the devices start up and are accepting commands. For example, a hard disk test would spin the drive up and test it to ensure the drive can be accessed.
Other checks include checking the keyboard. The check tests every key on the keyboard. Depending on the BIOS, if a stuck key is detected a warning message will appear.
Any devices like a mouse are also checked. This includes devices like trackpads and trackballs.

This section of the ITFreeTraining courses will look at the BIOS. BIOS or Basic Input/Output System is the software that is responsible for initially testing and communicating with your hardware. Without the BIOS the computer would not start. This video will look at what the BIOS can do, upgrading the BIOS and how the BIOS works.
