Boot camp not working

[Mufflen]

Hi i am trying to install windows 10 on my macbook air, but every time i try i run Boot Camp Assistant i gives me this error "Your disk cloud not be partitioned". I have tried to run the first aid in Disk Utility (as the error code says) in both recovery mode and booted in macOS. I have tried the "fsck -fy" in single user mode, and i still doesn't work. I cant figure out what to do now, can anyone plz help me?

 

I am running a MacBook Air (13-inch, Early 2015) 121 gb

macOS High Sierra version 10.13.1

 

Note: i have installed windows 10 on one of my friends macbook air (the same model as mine) and i works perfectly.

I don't recommend boot camp on a 128gb or even 256gb computer, unless your main has 100gb+ storage.  It uses 40gb when you partition (5ish for windows 35ish for storage in windows).  Even if there are programs you want to run on windows, there's not much benefit running it on a macbook air.
