[SOLVED] From Ubilinux to Windows10

I need to reinstall one of our UPboard's.
At this moment it has Ubilinux installed and an UEFI/GRUB thing.
It won't see my original USB stick with Win10/64 in the BIOS boot menu.
Please help!

I used Rufus 2.15.x
And by default it was creating: MBR partition for BIOS or UEFI-CSM
But it should be: MBR partition for UEFI
