A problem occurred when windows tried to activate. Error Code 0xC004F063. the Software Licensing servies reported that the computer BIOS is missing a required license.

I can tell you why you are getting this error. How to fix it depends on the reason you are getting this error.
Windows software licensing means that a copy of Windows is only valid for a Single PC. As part of the installation process the Licence key is linked to the motherboard of the PC.
The error is telling you that the Licence key you have for Windows has been activated and linked to a specific Computer B IOS. You can re-activate it on that computer, you cannot install it on another computer.
There are 3 reasons you can be getting this error

• You have changed the motherboard or the BIOS chip in your machine and you are re-installing Windows. The Licence will not be accepted and this breaks MS licensing agreement.
• You are trying to re-use an existing Windows Licence on a different machine - Not allowed using a OEM (operator installed) version of Windows.
• You have reinstalled Windows on your machine using a different installation disc - this can cause confusion when re-installing an OEM version of the software. e.g. Dell branded OEM Windows will only install to Dell machines.
