Sorry, but when you installed Linux, most likely, you corrupted the HP OEM Recovery information, so now, no such recovery is possible anymore.  You undoubtedly had to repartition your drive to make room for Linux, and when you did that, it "broke" the recovery process.

When you installed Linux, it overwrote the MBR on your dive to point to GRUB -- which is why you are getting that error message.

If all you want to do now is be able to boot into Windows and Linux, then do the following:

1) Boot into Linux

2) Open a terminal and enter "sudo update-grub"

3) Reboot

After you reboot, you should then see a GRUB menu with entries for Windows and Linux.

Good Luck

Hi WAWood,
It's posssible to do the update in linux platform, is it possible to access my windows 8 ...

I want to install new windows 10, is there any option to do...

While i was trying to install my new windows 10, its not getting boot..

Did you try the "update-grub" solution?

Asking because if that works, you might then have a working Win8.1 system.

With that working, we can then talk about a possible Win10 uopgrade.

Good Luck
