Hp laptop won't start up

[kayla420]

Got the laptop as a hand me down and was trying to factory reset it and it died in the middle of that process. When I go to reboot the laptop I click the option for Windows 10 (Volume 4) and the screen just flashes black like it's turning on and off rapidly. I've tried trouble shooting and have gotten the message "Unable to reset your PC. Missing drive partipn required."

This could be a couple of very different problems.

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

For the first, let's presume the drive is OK but the boot files are bad.  That is fixable.

Windows PCs use two different sets of files to get you to a working desktop.
In terms of the first, Windows boot files, you need to follow the instructions below to create boot media from Macrium Reflect (MR) that can be used to rewrite/repair the boot files on your PC:
1) Download and install Macrium Reflect (MR) from this link on a working PC:

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.

If that did not work, we have the second issue -- failing drive.
