I've lately been trying to upgrade to windows 10, which is available for free.
Since i have been using windows 7 for more 2.5 year on my desktop computer, I thought that now was a good time to do a fresh reinstall of windows from 7 to 10.
So I did a backup of all my important data to an external HDD, so they're all safe. I then tried to make a true clean install following this guide: https://youtu.be/K0oUuUsH4As?t=8m45s

Then THIS happened!!

How do I fix this?? please help

My computer:

Core i7 4770K
Asus Z87-Pro
16 gb ram
2x GTX 780 SLi
2x Samsung 850 250 gb SSD's (no RAID)
Corsair AX850W PSU

 
MBR was for old computers, since you have a UEFI bios you should be using GPT. This only happens on fresh installs, Win 10 seems perfectly happy on MBR if its an update but forces you to change when it comes to a fresh install.
 


Then how do I change MBR to GPT??
