Sometimes the operating system may not be compatible with booting in the UEFI system. In that case, you need to enable CSM (Compatibility Support Module) to install the operating system.
But do you know how to enable CSM from BIOS settings?
Well, I have analyzed some top-branded motherboards and enabled CSM from there. I will discuss those methods.
So, let’s begin.

How to Activate CSM in BIOS
To enable CSM, first, you need to go to the BIOS menu. For different motherboards, the boot menu key is different. For ASUS, Gigabyte, ASRock, and MSI motherboards, the boot menu key is F2, F12, F2 and Delete key.
Note: If your motherboard is not one of them, you can try the following path. You will likely find CSM in your particular BIOS.

FAQs
Should I enable CSM in BIOS?
It is not mandatory to enable CSM on your computer’s BIOS system. But, if your PC has an MBR device and doesn’t support UEFI, you should enable the CSM.
What does enabling CSM do?
When you enable CSM, the PC can boot in legacy BIOS features. It uses MBR instead of GPT to run the operating system.
Should I use UEFI or CSM?
Usage between UEFI and CSM depends on the drive size. You should use UEFI if your computer has a large drive (more than 2 TB). But if you have a small drive (less than 2 TB) on your PC, it’s better to use CSM.
Final Thought
Depending on the situation, you should decide whether your device requires CSM boot in Windows or not. Because it would cause the system to run more slowly.
When you switch off CSM, your motherboard’s UEFI support will be activated. You will need a suitable OS and BIOS version to control the system.
If you have performed the following steps, you should not encounter any problems with enabling CSM.
