Windows 11 is just around the corner and everyone is rushing to fix their systems to be compatible with the upcoming operating system. Windows 11 has certain security requirements that make it difficult to install the operating system on older systems with legacy components. A good example of this is the need for TPM, Secure Boot, and UEFI. These are all boot menu settings that enhance the privacy and security of your system, allowing the additional security features of Windows 11 to work well on your system. If you are using legacy hardware, you might have come across CSM. What is it? And should you disable it? Let’s find out!
WARNING: CSM is loaded! Enable TPM & Secure boot in BIOS for Windows11 update (GPT partition only)
CSM or compatibility support module is a part of your UEFI system. UEFI is a modern form of letting your hardware communicate with your OS through the BIOS. UEFI is fairly new and if you have CSM on your system you are probably running an outdated OS that is not currently supported by your UEFI system.
Therefore, CSM helps emulate a BIOS environment that is compatible with your current OS. By disabling CSM, you can enable UEFI on your system, which is necessary to install most modern compatible operating systems.
You will need to access your system’s BIOS menu so that you can disable CSM on your system. Depending on your manufacturer, use the guides below to get started. If your manufacturer is not listed below, you can use the general terms in the next section. These are the commonly used terms in BIOS menus that allow you to disable CSM. You can find the same in your specific BIOS and disable them at your convenience. Let’s get started.
