Grub Rescue Unknown File System when dualbooting

Hello. I want to install Windows 10 with dual boot.
So I reinstalled Arch, by manual partitioning I installed on 750GB, and made 200GB free partition for installing Windows later.
I made myself Windows USB, I press F12 then select the Windows USB to boot from it.
It says:
grub rescue unknown file system
As you see grub does not recognize my installer USB. How can I fix that and boot from that USB?

GRUB should be irrelevant from the perspective of your BIOS/UEFI selecting a boot drive. You are either not selecting the  correct drive  or you didn't create the stick correctly.
