If it is school property, just take to whoever is responsible of tech support.

It probably has a rescue partition but it's been some time since I had a Windows laptop.

You probably broke the installation by interrupting it mid way. You're never supposed to interrupt an update. 

Good luck

Its my own laptop. I bought it for my school. Hopefully this clears the misunderstanding.
