Hi,
Bootmgr is missing message can be a hardware failure but the good thing about is that you can still back your files inside the HDD. In order to back up your files, once you turned on your unit and received this message, press F1 to continue and let the computer load your desktop screen.
For further isolation about this you can also run diagnostics for HDD.
Restart the unit and keep tap the ESC button on your keyboard
It should show the Startup Menu and then select Diagnostics using the up and down arrow keys, press Enter afterwards
It should give some option on running a HDD check, if there was a failure ID or error code, please feel free contact HP support line. Now if its passed try to run a system recovery or factory reset on your unit if issue will remove
I hope this help you.....
