For your future information - you should never attempt both a ram upgrade and a clone at the same time, if that is what you did.
You either make the ram upgrade first and ensure the system still boots and loads windows and the ram is showing the new capacity.
OR the other way round, but not both before trying to boot
Until you posted I had never heard of EZ Gig however a simple search shows there are numerous reports of it failing and indeed suggestions that this is especially so on windows 10
Plus which the user manual does not even list it as suitable for Windows 10
You will find if you search - as I did that most major cloning software providers have articles on EZ failing
For instance
https://www.backup-utility.com/clone/ez-gig-iv-clone-failed-3889.html
https://www.easeus.com/backup-utility/best-ez-gig-iv-alternative.html
https://www.partitionwizard.com/partitionmagic/ez-gig-iv-alternative.html
I have used Easeus FREE cloning many times with no problems, both here on the site and personally for myself and other people.
That said many people recommend the other two as well AND most SSD suppliers offer their own cloning software#
That all said it should of course boot and load windows with the original drive installed
According to HP it came with a 500GB drive

however I do of course appreciate that it may have been changed
To clarify DID you check if it booted and loaded windows with the additional ram and the original drive BEFORE making the clone.
IF NOT I suggest you take out the additional ram
leaving in the original drive and then try entering BIOS/UEFI firmware and see if the drive is then recognised and the boot is to Windows Boot Manager
and it loads windows.
IF it does I then recommend you dispense with the EZ Gig and clone with either one of the links or the cloning software from the SSD manufacturer
