How to recover Windows key from failed hard drive BIOS

[Ddrite46]

   Greetings to all,

   My question regards an HP Pavilion x360 - 11-k117cl (ENERGY STAR)

  On lifting the lid from sleep it displayed the dreaded "Boot sector not found" message. Hardware diagnostics yielded a failure code which translated on    the   HP diagnostics page as hard drive failure.  POWER + ESC ----> Startup menu. I can get to System Info, System diagnostics, and select boot device. I cannot get to BIOS setup, where I presume lies the Windows key.

The hardware solution is replace the HD, but how to retrieve the Windows key from BIOS? Can I get it after replacing the HD? I would like to be sure I can access the key before investing $$.

Thank you for any information about my issue.

Normally the KEY entry can be skipped and will register AutoMagically, however.....

You could try dropping to the Command Prompt and...
Doing research, and none of the methods are mine, I have some, simple single lines of code that will list the same value for your Windows 10 Product Key…

W10 Using cmd.exe as an Administrator (copy and paste accordingly).

Last, but not least....
