Can't run setup after factory reset

I've inherited my uncles MacBook Pro model a1278 after he died. I had no way of guessing his password so reset it factory settings. I went through the setup process and put in my existing Apple ID and password, it went to the spinning pinwheel at this point and then nothing. After an hour I assumed it had crashed or something so force closed and went through the process again although now it gets as far as "select your keyboard" then gets stuck every time. What do I do now? I'm not a mac user only use iPhone so am a bit stuck. I don't have any recovery disks or anything but the laptop itself. It's a shame to abandon it as it's hardly been used so is in great condition. Cheers in advance!
