This is not a personal criticism -- but all hardware fails, eventually -- which is why, if you can't afford to lose something, you need to spend a little money and time to back that stuff onto a USB stick.
Since you apparently did not bother to do that, and your laptop now won't boot into Windows, if this were mine, I would focus on recovering the files I needed from the drive. To do that, you will need a couple of USB sticks and to read the information below about making a boot USB you can use to boot your PC and then copy the files to the other USB stick.
If your PC can not boot into Windows, a way around that is to follow the instructions below to create boot media from Macrium Reflect (MR) that can be used to boot your PC even if the hard drive is not working: 1) Download and install Macrium Reflect (MR) from this link: http://www.macrium.com/reflectfree.aspx 2) Use the option to create a boot USB stick or CD
That will create MR bootable media. Then, you can boot your PC into WinPE using that media.
Have patience, as that can take a while to start and bring up the screen.
