Upgrade a 13" Early 2011 MBP to Windows 10 from Windows 8.1

I have never seen the word Windows written in there . . . only EFI both for the USB Stick or the Windows partition

You should see 3 or 4 options. Macintosh HD, Recovery HD, Windows and EFI Boot (the last two are from the USB with the USB Symbol).

I only have MAC (renamed from Macintosh HD), EFI (2nd HDD) and EFI (USB symbol)

Is it possible to post diskutil list from OS X with the USB plugged in?

there

This is a usb stick that i have just made MBR and FAT32 and it doesn't even recognise it when i boot with OPTION key

And this is another usb stick that i've made yesterday for my desktop it doesn't gave MBR it's GPT and it says EFI

Did both these USB sticks get built using BC Assistant?

None of them were !

Can you insert this disk and post the output of

diskutil list

sudo fdisk /dev/diskN

N points to the USB which is shown in the output of the first command.

Your Mac (2011) does not really support USB booting, so we will see such issues. Let us see what you get from the above two commands.

Maybe it only supports EFI boot.

On my MBP, there are differences on my MBP using the BCA-created USB.

I don't see any option that could let me make bootable usb from BCA

Can you post the file structure for the USB from Finder? It should look similar to the following.

it's almost the same without $WinPEDriver$ and AutoUnattended.xml but i think this is because i didn't download the bootcamp drivers via BCA
