What does changing to UEFI do?
There are further advantages: UEFI can manage partitions and hard drives with a capacity of more than two terabytes, supports not only the classic MBR format (Master Boot Record) but also the GUID partition table (GPT) and can handle up to 128 primary partitions — with BIOS there were only four.
What happens if I change UEFI firmware settings?
Important: Under normal circumstances, there's no need for you to change UEFI settings. If you change these settings, you risk the security and functionality of your Surface.

What are the disadvantages of UEFI BIOS?
Disadvantages of UEFI
The Unified Extensible Firmware Interface also has some disadvantages. UEFI has limited compatibility because it only supports 64-bit systems. While these are increasingly becoming standard, 32-bit systems are still widely used, especially in the Windows ecosystem.

The conversion usually works fine. But if Windows has put some system partition on another drive or if you have multiple OS on multiple drives, it can get messy. After the conversion (and restarting the system), System Information should show UEFI as BIOS Mode.
Why should you not update BIOS UEFI unless a computer needs it?
Motherboard manufacturers warn against updating your motherboard if your PC is working normally. Risks of updating your BIOS include corruption if power is lost during the minutes-long update or if a crash occurs. Updating also resets BIOS settings to their default values, which could impact system stability.
Is it safe to switch to Legacy boot?
It won't cause any damage. Legacy mode (a.k.a. BIOS mode, CSM boot) matters only when the operating system boots. Once it boots, it doesn't matter anymore. If everything works as expected and you're happy with it, legacy mode is fine.
Is GPT for UEFI or MBR for BIOS?
UEFI mode is compatible with the GUID Partition Table (GPT) partition style, while the legacy BIOS mode is compatible with the Master Boot Record (MBR) partition style. Most of the latest features and capabilities are only available in UEFI mode.
Should I install Windows on UEFI or Legacy?
In general, install Windows using the newer UEFI mode, as it includes more security features than the legacy BIOS mode. If you're booting from a network that only supports BIOS, you'll need to boot to legacy BIOS mode. After Windows is installed, the device boots automatically using the same mode it was installed with.
Is Legacy boot better?
Legacy boot mode is an older method of booting up a computer, and it is compatible with older operating systems. However, it has certain limitations, such as the inability to boot from disks larger than 2TB. UEFI boot mode is a newer standard that offers many advantages over legacy boot mode.

Is UEFI required for Windows 11? The answer is yes. But with the help of AOMEI Partition Assistant, UEFI is no longer a hinder to the Windows 11 upgrade. You can convert MBR to GPT disk safely.
Is BIOS still used?
In modern PCs running modern operating systems (such as Windows and Linux) the BIOS interrupt calls is used only during booting and initial loading of operating systems. Before the operating system's first graphical screen is displayed, input and output are typically handled through BIOS.
Which is faster MBR or GPT?
Although both GPT and MBR work fine, to have a speedy Windows boot, GPT is the better choice yet again. And because you require a UEFI-based system for faster bootup, and UEFI only works with GPT partitioning. So once again, GPT seems the more logical option when it comes to MBR or GPT for SSD.
Does Linux use UEFI?
Unless your computer is pretty old, it probably uses UEFI (Unified Extensible Firmware Interface) to boot. The idea is that a bootloader picks up files from an EFI partition and uses them to start your operating system.
Is it bad to disable Secure Boot?
Disabling/enabling SecureBoot doesn't affect already installed operating systems in any way. The only thing SecureBoot (if enabled) does is to verify that the Operating Systems bootloader has a valid security certificate and it refuses to boot it it doesn't have one.

Legacy BIOS is the old mode that uses a 16-bit code and a limited number of options.
Is GPT UEFI or Legacy?
There is the Legacy mode (BIOS + MBR) and UEFI mode (UEFI + GPT). UEFI needs an EFI driver which only can be created on a GPT disk. Since GPT boots the system in a different way than MBR, if you use the traditional system installation method can cause a 'Cannot be installed to this disk' error.
