As per your description, you are getting the error: "Your PC need to be repaired

File: \Windows\system32\winload.exe

Error Code: 0xc000000e” while trying to boot your Windows 8 computer.

If you have the Windows 8 installation media, then I would suggest you to run an Automatic Repair of Windows 8 using the installation media. You can perform this by following these steps:

a)       Contact the computer manufacturer to know on how to change the boot order of the computer. You will have to change the boot device to CD/DVD drive and then boot from the Windows 8 installation disk.

b)       In the “Windows Setup” dialog box that appears, set the Time and currency format, Keyboard or input method and the language to install and then click “Next”.

c)       Click on “Repair your computer” from the lower left corner.

d)       From the “Choose an option screen”, click on “Troubleshoot”.

e)       Click “Advanced Options” in the “Troubleshoot” screen.

f)        In the “Advanced Options” screen, click “Automatic Repair”.

g)       Follow the on-screen instructions to complete the Automatic Repair.

Start by booting the computer with the recovery media inserted. The computer should load the CD or USB. (You may have to change the BIOS boot order to boot the USB drive first.)

Choose your language. Click Next
You will now see Install in the center of your screen. On the lower left side you will see Repair your computer.
Choose the repair option.

You will have several options including:
Refresh Your Computer
Restore Your Computer
Advanced Options

Choose Advanced Options.
Launch the command prompt

bootrec /scanos
