To disable CSM (Compatibility Support Module) in BIOS setup, follow these general steps:
- Restart the computer and enter BIOS setup by pressing a key such as F2, Delete, or another specific key depending on the motherboard manufacturer during boot.
- Navigate to the Boot tab within the BIOS.
- Locate the CSM or Launch CSM option.
- Set Launch CSM to Disabled (or select UEFI only in Boot mode if that option is available).
- Save changes and exit BIOS (usually by pressing F10).
Details for popular motherboards:
- Asus: Boot tab > Launch CSM > Disabled > Save & Exit.
- Gigabyte: BIOS tab > CSM Support > Disabled > Save & Exit.
- ASRock: Boot tab > CSM > Disabled > Save & Exit.
- MSI: Boot tab > Boot mode select > UEFI only > Save & Exit.
Disabling CSM typically switches the system to pure UEFI mode, enabling Secure Boot and support for GPT drives, and enabling faster boot times. It is recommended to disable CSM if running Windows 10 or newer with GPT partitioned drives.
If Secure Boot needs to be enabled along with disabling CSM, some systems require disabling CSM first, saving, then rebooting and enabling Secure Boot afterward from the BIOS security tab.
If you encounter difficulties disabling CSM or the option re-enables automatically, it may be due to BIOS limitations or settings conflicts. Updating BIOS or consulting the motherboard manual/support is recommended in those cases.
This guidance covers the general method to disable CSM in setup BIOS. If a specific motherboard or model details are needed, please specify.
