Many modern PCs run the installed OS in UEFI mode. But almost all of them have a fallback mode which allows the hardware to be configured in the legacy mode called BIOS mode. Here is how you can tell which mode exactly is used on your Windows 10 PC.
Press the Win + R hotkeys together on the keyboard and type the following command in your Run box:
msinfo32
Tip: See the ultimate list of all Windows keyboard shortcuts with Win keys.
That's it. You can use this information in case you need to create some bootable media such as a USB stick. Using the output from MSInfo32, you can be sure which type, bootable UEFI USB stick or bootable USB stick (legacy) to create to install Windows 10.
Msinfo32 also lists the Secure Boot State, your PC's motherboard manufacturer and your BIOS Version/Date. It has plenty of interesting information about your PC.
