My pc won´t boot Windows 10 from USB/DVD

So I wanted to change from my Windows 10 x32 bits to 64x. I downloaded the Mediacreationtool and used it in both a USB and a DVD. Tried used the usb, the disk and both at the same time but they won´t boot.

I have a P7H55-M motherboard, the BIOS is updated and configured to boot first DVD, second usb and third SATA.

So if someone could help me it´d be great.
