How should I perform a system repair or system restore if I'm not able to go through the welcome screen itself? Can it be done from boot serup?

On start up repair it gives the following message
Status: 0xc00000e9
Info: An unexpected I/O error has occurred.
Does it mean my hard disk has been damaged?

I dont have any bootable windows disc. Because I've even lost my drivers CD. But that's not a problem because I'll arrange all that if there's a problem with windows and not any hardware fault. But here I'm not able to understand what is wrong in my laptop.
