What is boot mode UEFI with CSM?
UEFI and BIOS are used interchangeably nowadays, but your motherboard most likely uses UEFI. Enabling CSM allows for legacy BIOS features that aren’t supported in normal UEFI mode. CSM uses an MBR (master boot record) to boot the operating system. UEFI uses files within a larger partition to boot the OS.
Should I enable CSM in BIOS?
The answer depends on your Windows versions. If your computer is fairly new and comes with Windows OS pre-installed, the BIOS CSM is usually disabled by default. For example, if you are ready to install/reinstall Windows 10 on a new SSD, you don’t have to enable CSM support while installing.
Can I boot from USB in UEFI mode?
If the Boot Menu isn’t available, you can force your computer to boot from an external and removable media (such as a USB flash drive, CD or DVD) by configuring your BIOS/UEFI settings. Newer computers models with UEFI/EFI need to have the legacy mode enabled (or disabling the secure boot).
What happens if I change CSM to UEFI?
UEFI is basically the new BIOS, performing the same job but better. With UEFI, you get faster boot times (ostensibly), higher drive capacities, better update methods and driver support, and a 64-bit mode (where BIOS is only 16-bit). In other words, switching to UEFI is a bit of an upgrade and worth doing.
What boot mode should I use?
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.
What is the difference between UEFI and CSM boot?
The Compatibility Support Module (CSM) is a component of the UEFI firmware that provides legacy BIOS compatibility by emulating a BIOS environment, allowing legacy operating systems and some option ROMs that do not support UEFI to still be used.
Is CSM secure boot?
CSM is a parallel item with Secure Boot. Through CSM, UEFI firmware implementations on PC-class machines can also support booting in legacy BIOS mode from MBR disks, because CSM provides compatibility for the legacy systems.
How do I know if my USB is UEFI?
The key to finding out if the installation USB drive is UEFI bootable is to check whether the disk’s partition style is GPT, as it’s required for booting Windows system in UEFI mode.
Which boot mode is better UEFI or legacy?

Is UEFI better than Legacy?
Nowadays, UEFI gradually replaces the traditional BIOS on most modern PCs as it includes more security features than the legacy BIOS mode and also boots faster than Legacy systems. If your computer supports UEFI firmware, you should convert MBR disk to GPT disk to use UEFI boot instead of BIOS.
Why is my USB not bootable?
Restart the system into the BIOS. Ensure the Boot Mode is set to EFI (or UEFI). This is found in the Boot Options menu. Make sure that the USB Boot Priority is enabled.
Should UEFI boot be enabled?

Does SSD use UEFI or legacy?
It will depend on the SSD you install. If you install an M. 2 SSD (assuming the laptop has an M. 2 connector) you’ll probably need to use UEFI to get it to boot.
Which is better legacy or UEFI for Windows 11?
Is CSM the same as secure boot?
Do I need to disable CSM for Windows 11?
Hence, CSM helps emulate a BIOS environment that is compatible with your current OS. Disabling CSM will allow you to enable UEFI on your system which is needed to install the most modern compatible Operating Systems.
Which boot mode should I choose?
Does UEFI speed up computer?
