[SOLVED] CSM or UEFI?

[Drew2345]

So i just installed a new mobo ( msi b450 pro carbon max wifi)and watching a guide in installing windows after build the guy said to change CMS to UEFI in the bios settings even though its optional. So I basically have no idea what UEFI or CMS is and now i dont know which one should i use

csm is used for legacy hardware/operating system (like windows 7 combined with some aged addin cards which doesnt have uefi bios)
