[Juan63]

My Elitebook is not booting. I am getting this message "Bootmgr image is corrupt". I don't have a recovery disk, neither a windows installer disk. Windows 10 was preinstalled by the manufacturer. This laptop don't have CD/DVD drive. I have a windows license number already registered. Please let me knoy how to proceed to solve this problem.

Hello;
Allow me to welcome you to the HP forums!

There are a couple of likely scenarios here -- either of which could be the case.

First, the boot loader records could have become corrupted. If that is the case, the Windows OS is still there but you can not boot to it and the PC does not see the OS, as a result. This is something that with a second PC (used to download stuff and create boot media) can be repaired with a little work.

Second, the OS could have been corrupted to the point it will no longer initialize properly.  This is much more serious and would required reinstalling the OS.

Let's deal with the first one and hope that fixes your PC.

You will need to create Boot Media using a working PC -- as there is no way to repair this on your current PC.
 
There several different solutions for this, all of which are free and all of which work ...
 
1. Macrium Reflect
 
This 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 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 and select the option to repair the Windows Boot
 
2. Neosmart's Easy Recovery Essentials
 
As far as I know, this is also Free -- and here is a link describing it:

3. Doing Startup Repair using Win10 install media
 
Download and create Win10 install media from this link: http://windows.microsoft.com/en-us/windows-10/media-creation-tool-install?ocid=ms_wol_win10
 
Boot from the media you created, and follow the directions in this link:  http://www.windowswally.com/how-to-fix-error-code-0xc0000185/
 
You will probably have to run Startup Repair three times for it to fix all the boot loader problems.
