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.

On an older computer that does not support UEFI, MBR partitions are 5-6x faster than GPT. If you have an olde computer, do NOT use GPT

In this case it did not do a huge differnece but it will on hardware that still uses hardisk

"Why GPT? Because the older MBR is unable to address storage media capacities higher than 2, 199 GB" - It's so actually for 120GB Samsung SSD that you have))

I'm looking for a video like this but for linux. Wondering how much time uefi would shave off the boot time.
