Help replacing primary HD in HP laptop

[derail43]

I have an HP Win 10 laptop and shortly after the warranty expired it started doing random restarts. I ran diagnostics on it and it indicated that the hard drive was the problem. When it started doing the restarts, I created a recovery DVD and I have it on hand and would like to use it on the new drive. I bought a new Western Digital HD for it (the original was Seagate). It has probably been at least 20 years since I set up a new HD from scratch and I don't feel comfortable doing it now.
Can anyone give a step by step? Thanks much!

Recovery DVD is not going to help in this case, you need to replace disk and install OS on it.

Recovery disk is used to restore your current system to a new drive only in the sense that you need it to restore the backup system image, which you need to create first. It's also what you use to boot your system up when your installed version won't so you can troubleshoot or to install windows fresh (from scratch). Its like an improved version of the old F8 option which Windows no longer has.

To make a system image of the current drive.
Search for & Run Backup and Restore &^Run Create a System Image. You will need several blank disks (4+ depending on how full) or an external HDD. I highly recommend the external HDD since they can hold multiple images. The app will tell you how much space it needs to make the image.

To restore the image:
Boot from your recovery disk. Windows will load and ask you to verify a few settings, like Language. Click Next when they are correct for you.
You will now be presented with the Install Now screen. - Click on Repair my Computer followed by Troubleshoot.
Next click on System Image Recovery, select your OS (win10 I assume), and then the Use latest System image option.
Because you did a full system image, select Format and Re-partition disk.
You will be asked to verify and then click Finish and stick around to swap in the disks you made if you didn't use an external HDD.
