Hello Michael
There are a number of conditions to make a proper diagnosis without having to make up your device:
1) Your Bios must be set up to boot from a USB port.
2) You must have a USB stick or an external hard drive with a portable Windows version, your case Windows 10.
You can solve the first by adjusting the boot order in the bios.
For the second you need software and another PC.
You get it from the MS site and choose “Download tool now”:
https://www.microsoft.com/en-us/software-download/windows10?
Follow the instructions so that you have the same version of your PC as portable windows on your USB stick or your external hard drive.
The rest is a matter of connecting, booting and seeing if it detect your old hard drive.
Good luck
