Dell installation - Grub won't detect Windows [SOLVED]

Hi all,

I'm installing Arch Linux to dual boot with Windows 10 on a Dell Inspiron 15 7000. I now have the Arch installation working, but I can't get Grub to recognise Windows and add it to the menu.
Windows is still working fine, I just have to enter the Boot menu to boot it. I have turned off Secure Boot and Bitlocker, then run os-prober and grub-mkconfig to pick it up, but it still only sees Arch.
I tried mounting the Windows partition to see if that would work, but it made no difference. This is an EFI system. I mount /dev/nvme0n1p1, which contains Windows' EFI files on /boot and install Grub and the config files there.
Is there something else I need to do to get Arch to see Windows?

Thanks

Turns out running os-prober and grub-mkconfig after booting into Arch directly solved the problem. I did it initially from the livecd in arch-chroot and it didn't work there. All sorted now.
