I have a laptop that windows 8.1 on it, is there a way to transfer it to a new gaming desktop that i'm building? the desktop has no operating system on it
Contrary to the above comment...almost certainly not.
The OS license for that laptop is almost certainly an OEM license, and as such is licensed to that particular motherboard.
And even if you could, now the laptop has no valid OS.
Your new desktop needs its own OS.
Solution? Sell the laptop. Buy a new OS with the proceeds.
