OS not found

[Shantriestechno]

Hi guys! 

I tried factory resetting my Pavillion DV6 notebook in preparation for uni. It obviously went wrong.

When I power on my laptop it says that my battery is dead (knew that already) and then it shows a screen which reads:

"An operating system wasn't found. Try disconnecting any drives that don't contain an operating system. Press Ctrl+Alt+Del to restart"

I have run the primary hard disk self test which passed so I think it is just having issues working out it is alone?

Can anyone help?

Thanks so much!

If your PC can not boot into Windows, a way around that is to follow the instructions below to create boot media from Macrium Reflect (MR) that can be used to rewrite/repair the boot media on your PC:
1) Download and install Macrium Reflect (MR) from this link: http://www.macrium.com/reflectfree.aspx
2) Use the option to create a boot USB stick or CD

That will create MR bootable media. Then, you can boot your PC into WinPE using that media.

Have patience, as that can take a while to start and bring up the screen.

Once the screen is there, select the option to Fix Windows boot problems. It will then search for the OSs installed and list them, Select the one you want to repair and click Next.

It will now do the repairs, listing the things it has done.

When finished, select the option to Restart the PC.

If this worked, the boot repair succeeded and you will have your PC back.
