Help with Laptop

Hello!

My husband recently got a new work laptop and he gave me his old one (An Asus G53S) It’s older, but it gets the job done, and much better than my old 2010 dell.

My biggest thing is it does a dual boot (I guess is what it’s called), when it’s turned on a menu comes up that says

Linux Mint 16 Cinnamon 64-bit
Linux Mint 16 Cinnamon 64-bit
Memory Test (memtest86+)
Memory Test (memtest86+, serial console 115200)
Windows 7 (loader (on /dev/sda1)

It’s not actually windows 7 anymore, it was upgraded to windows 10, but how do I get it to just boot straight to windows? I’d ask him, but he’s been really busy with work =(
