[SOLVED] Grub2 EFI and Windows 7

Hi to all,
I am using arch x64 on a laptop with also windows7 installed in UEFI mode and GPT. I have always been able to use also windows by starting it form grub2, which has to call window's boot manager .efi. However, recently I installed grub again due to some systemd issues. Now the entry for windows disappeared and I don't remember how I did last time. If I try to probe windows's boot manager (following the wiki) it can't find a grub device for it. Maybe it's because the efi partition does not get mounted when using arch?

 grub-probe --target=fs_uuid /boot/efi/EFI/Microsoft/Boot/bootmgfw.efi.backup 
error: cannot find a GRUB drive for /dev/sda3.  Check your device.map.

Ok I solved, it was just because I wasn't using the command as root
