OS: windows 10 pro retail
Build: 1903 OS Build 18362.356
computer: custom built
install type: from scratch, not an upgrade


Hello,



When I try to activate windows with my product key I get "Unable to activate windows" and get an error code 0x803fa067 no letter l or L at the end. Help please.

:)

 

in other words dual boot W10PRO ... one key w10pro.

dual boot... one key w10pro.

I have a tricky Q

I have two bays/drives HDD (C:/ w10pro 650GB+ T:/ 350GB) +( D:/ 500GB) currently

if take the D:/ out AND IN ITS PLACE put SSD and install W10Pro (same key as C:/ - is upgrade from 8.1 pro needs key???) on SSD

can boot choose on turn on of PC either from C:/ or from SSD???

in other words
dual boot W10PRO ... one key
w10pro.

IF CAN, HOW FIND KEY W10PRO IN CURRENT???
