Well, it seems you are missing the Boot thingy.
With out this the computer will not boot.

bought computer new pair of boots, She's now 100% fab.
It means the hard drive your computer is loading from does not contain bootmgr which is required to load into your OS. So when starting up enter BIOS and navigate to your boot options and select the correct partition/drive that contains your Windows 10 OS.
