This Is Not a Good Time For This

I thought it would be nice to check my email before I left Ash's place this morning, so I pulled out my laptop and pressed the "on" button... and got the message "Operating System Not Found".

Now what?

I'm kind of scared to try anything because I took the bar on my laptop, which means that I am not allowed to mess with the hard drive until the results are released. But I cannot wait months to use my laptop again. For one thing, all of my job search stuff is on it, including my CV.

But truly, I don't know where to start. Any of you have some advice for me?
