Cant Install Windows 10 techinical preview on my hardisk?

[Schezan Mansuri]

I downloaded the technical preview.
And when I tried to install it in my internal hardisk I get an error saying cant install in your hard drive as it is of efi format and they want it to be of gpt format .
If someone can explain me what is the difference between these two and also a solution for my problem >?
Thanks a lot help appriciated
Have a great day ahead
And I am using windows 7 64bit.

tech preview says.. you should not try it unless you know what you doing..
You don't ... (you don't even know how use google!!! ;-) )
Wait for a customer preview.. or release.
Cheers

I can google that but its also better to ask someone who already knows about it so I may not run into any trouble
