My sister likes to bush buttons, any buttons, all buttons. As a result, I felt her computer could not be fixed. I reinstalled Windows 10 pro for her from an ISO I got from MS. I had to reinstall Windows within Windows. USB would not work. The installation went well.
Novice me, I thought I could use the CD Key stored in the BIOS for activation. Apparently that key was erased and replaced with a default key supplied by MS during installation. Now, it looks as is I will have to purchase a digital license from MS.
AS the original CD Key was purchased legally along with the refurbished computer (from Dell, I think), why could it not be used? It was paid for? This is assuming I could find the original key. It is not on the case. I do have service tag #.
