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.
What does changing CSM to UEFI?
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.
What happens if I change boot mode to UEFI?
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.
Do I use CSM or UEFI?
While CSM uses the standard MBR (Master Boot Record) partitioning scheme, UEFI uses the more advanced GPT (GUID Partition Table). GPT offers many benefits over MBR, such as increased flexibility and compatibility with large disks. As a result, UEFI is now the preferred bootloader for most users.
Does disabling CSM enable UEFI?
The UEFI and CSM boot mode go hand in hand. If either one is disabled, the other one will be automatically enabled. For example, if you set the CSM disabled, it means that UEFI supports will be enabled on your motherboard.

Should I enable UEFI mode?
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.
Should I disable CSM for Windows 11?
This component provides legacy hardware compatibility by imitating a BIOS environment. It results in losing certain UEFI features essential for the Windows 11 update. Hence, you’ll need to disable CSM to run the latest compatible operating system.
Does converting to UEFI delete data?
15063) or later, you can take advantage of the UEFI without having to reinstall Windows, by using the MBR2GPT. EXE command line tool. In this tutorial you ‘ll find detailed instructions to change the Legacy Boot to UEFI Boot, without having to reinstall the operating system and with No Data loss.
Is it safe to change Legacy to UEFI?
In conclusion, it is recommended that you change Legacy to UEFI boot mode if your operating system (OS) is compatible. As you can see, the entire process doesn’t take much time or effort since as you don’t need to reinstall Windows 11,10, 8, and 7.
Is UEFI faster 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.
Should CSM be enabled or disabled?
To put it in a nutshell, CSM exists to provide compatibility with systems that support or do not support UEFI completely, as well as systems that must be installed in Legacy. Therefore, if you need to boot a traditional MBR device, you need to enable the CSM.
Is CSM Secure Boot?
CSM Support is used for booting from legacy devices, which is the exact opposite goal of Secure Boot. Custom would allow us to set the keys used for attestation for Secure Boot.
What is UEFI boot mode?
UEFI Mode (default)—Configures the system to boot to a UEFI compatible operating system. Legacy BIOS Mode—Configures the system to boot to a traditional operating system in Legacy BIOS compatibility mode.
Does Windows 10 require UEFI?
No, Windows 10 will continue to support legacy BIOS. For new devices that are launched a year after the release of Windows 10, they must have UEFI and Secure Boot enabled at the factory. This does not affect existing systems.
Should I enable fast boot?
Leaving fast startup enabled shouldn’t harm anything on your PC — it’s a feature built into Windows — but there are a few reasons why you might want to nevertheless disable it. One of the major reasons is if you’re using Wake-on-LAN, which will likely have problems when your PC is shut down with fast startup enabled.
Does CSM work with GPT?
Yes, but from my experience, it is better to format the drive that you’re installing windows on into GPT first, and then disable CSM on the bios, and proceed install as normal.
Should CSM be enabled or disabled?
