I have a new computer and I have installed windows 7 home premium 64 bits. My motherboard is only compatible with GPT partitions, I tried the activation of the daz loader and the partition is not compatible. Therefore this system cannot use it. can someone explain to me in detail (I am not very expert) how to obtain a digital license of windows 10 home by updating from windows 7, 8 or 8.1 home or failing that, another system that is currently valid. Thank you.
