HDD unreadable

[RiBi]

When starting my laptop, it says there is no boot device available.  I've purchased an external HDD caddy.  It's not really reading much; it will sometimes show the main 932 GB and recovery disk briefly, but I cannot access them.  It says the main disk is not a system disk.

Is there an ISO I can get containing the original software that came on the laptop?  If so, do I need to copy the image to the same size drive?  I have also obtained a 500 GB SSD to replace the original HDD.

Once I get everything working again, I will need to know the orginal Win10 product key.  I don't see any information about drivers and software on the product page,

In terms of your questions ...

First, no, there is no ISO you can download from HP.  HP does not post stuff like that online.

Second, you don't actually need the product key.  That is embedded in the BIOS firmware and is used my MS to activate Win10.  So, once you get Win10 reinstalled and go back online, it will reactivate automatically.

Third, the Win10 drivers and software for your model PC can be found on this page:  https://support.hp.com/ie-en/drivers/selfservice/hp-15-bs000-lapatop-pc/15551412/model/16901645
