Hello;

Allow me to welcome you to the HP forums!

This situation is usually caused by a corrupted file system -- which can often be caused by a failing hard drive.

To check that, you have to follow these steps:
1) Press Esc key repeatedly, several times a second, while rebooting the laptop. Do NOT hold the key down, just press it over and over.
2) Eventually, you will see an HP Startup Menu -- that will look similar to the image below ...

3) press the Function key for testing the hard drive (usually F2) and let it run.

Please report back the test results.

If the hard drive checks out OK, then you MIGHT be able to fix the filesystem problem using a Windows Repair Disk.

You will need access to a working PC for this step in order to create the media needed to repair your PC boot loader.

You will need to create something known as a Win7 Repair CD. This will repair the boot loader files, and if that is the problem, your PC will boot OK after that. This can be obtained (for a fee) from this link: http://neosmart.net/blog/2009/windows-7-system-repair-discs/

When you download this file, it will be an ISO file.

To make a bootable CD from it, you will need to download and install ImgBurn: http://www.imgburn.com/

Once you have that installed, run it, select the option "Write image file to disc" and select the ISO file you downloaded, and point it to a blank CD.

To make a bootable USB stick from it, you will need to download and install RUFUS: https://rufus.akeo.ie/

Once you have that, run it, in the Device entry, use the pulldown to select the USB stick. Down near the bottom right, where is says "Create a bootable disk using", select the ISO file you downloaded.
-------------------------------------

Boot from the media you created, and follow the directions in this link: http://www.sevenforums.com/tutorials/681-startup-repair.html

You will probably have to run Startup Repair three times for it to fix all the boot loader problems.

When done, your PC should boot OK. If it does not, there is a more serious problem.

Good Luck
