Question Mark On Start Up?

Hi all,

I'm having a serious problem. Every time I turn on my macbook a question mark appears with a greyed-out folder. I've researched it online and the best solution, it seemed, was to put the installation disks in and reinstall. The problem is, my macbook just spits them back out. I'm really worried. I have uni' assignments to hand in after Christmas and, although most of my work is backed up, I need all the software on my computer. My last backup was about three months ago - and I really, really need to retrieve some of the files.

Any help is welcome.

Thanks in advance.

Have you investigated here? A flashing question mark appears when you start your Mac

Yes, but it didn't solve my problem.

I really need to retrieve the data. Coincidentally my pen drive's broken. I'm failing university because of this.

Can you start your computer in Safe Mode? How To Start Your Mac In Safe Mode (Technology & Cars: Protecting Your Computer) and Mac OS X: Starting up in Safe Mode Keep us informed, we'll help as promptly as we're able.

Meantime, in your situation, plead with whoever is to receive your assignment, surely they have others to assess.
