Update on this issue:
Resolving this issue has been very frustrated and time consuming.
Here is what I did to take care of this slow boot problem.
The original 256gb M2 boot drive was removed and replaced by a new M2 drive.
A fresh Win 10 pro OS was installed followed with updating all necessary drivers ordinarily required for a new pc including HP Support Assistant.
Voila, the pc boots up nicely with the 10tb drive and recognizing it without delay,
I tested with several other combo such as adding 2 of 10tb drives, 2 drives of 4tb / 10tb, 10tb / 500gb SSD, etc...
everything ran without a hitch.
I do not know what is wrong with the original built-in Win10 pro done by HP.
Apparently, crashing the whole OS with new hardware and OS is my desperate choice after wasting so much time to find a solution.
Any answer or guidance to this issue is very much appreciated.
Thanks
