How do I switch from Legacy BIOS to UEFI?

Thanks for the reply. No, this isn't even an option for me. My computer's BIOS is in Legacy mode not UEFI. Therefore, I don't even get this option. But I'm looking for one like it. Nothing I've tried has turned up a good way of accessing the BIOS settings in Legacy. And upon looking at Sony Vaio SVJ202 motherboards on eBay, it doesn't appear that my motherboard has a CMOS battery I can use to reset the BIOS to it's factory UEFI mode. In short, the roadblock is that I need to find some kind of firmware settings or reset the firmware but because I'm in Legacy mode, I don't know where or how. It's not as easy as it is in UEFI mode.

I took as much of the computer's back apart as I could, but I couldn't find a CMOS battery.

I'm afraid you have to take your whole computer apart.

@kelsey,

Normally, you may be able to press the power button to turn on your Sony Vaio laptop, and then immediately keep tapping the F2 key or ASSIST button (may vary) until you see the boot menu.

From there, you should be able to use the arrow keys to select Enter Setup, and press Enter.

"Enter Setup" is at the bottom of my boot menu.
