Recovery Message -Your PC/Device needs to be repaired Error Code:0xc0000185. 

How do I repair the Notebook? Are there recovery tools available online?

This message means one or more of the Windows boot files has become corrupted.  This is most likely caused by a failing hard drive.

If your PC is new enough to support UEFI, you can use these steps to test the hard drive: http://support.hp.com/us-en/document/c00439024

If not, to check the drive 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
3) Press the Function key for testing the hard drive (usually F2) and let it run.

-------------------------

If the drive checks out OK, then you can follow the instructions below and use another PC to create the media you need to rewrite the boot files on your PC.

Macrium Reflect is a free tool that can be used to image and restore PCs, but it also has an option to create Rescue Media (in disk or USB form) that can then be used to bot and/or Repair your PC.

It is available from here: http://www.macrium.com/reflectfree.aspx

What I recommend is the following:
a) Download and install Macrium Reflect (MR)
b) Use the option to create a boot USB stick or CD
c) Boot your PC from the MR media -- it will take a while, so be patient!
d) If needed, select the option to repair the Windows Boot

The PC should now reboot without problems. IF it still has problems, there are other issues at play.
