Dual boot Windows multiple HDD os-prober problems

Hi,

I'm here because I've ran out of ideas. Let me explain the problem.

I have a running Windows 10 on an SSD with a data partition on another HDD.
This other HDD is also the HDD I want to use to install Arch.
So I made partitions on the HDD for windows and Archlinux.

Now, the problem I'm having is that os-prober doesn't recognise Windows and I don't know why but displays this error:

Generating grub configuration file ...
Found linux image: /boot/vmlinuz-linux
Found initrd image: /boot/initramfs-linux.img
Found fallback initramfs image: /boot/initramfs-linux-fallback.img
  /run/lvm/lvmetad.socket: connect failed: No such file or directory
  WARNING: Failed to connect to lvmetad. Falling back to internal scanning
MORE ERRORS HERE
done

I can't redirect the errors (which is weird). It seems they're not on stderr or stdout.

Here's my fdisk -l:

Is there a way to fix this?

Thank you!

Your Windows system boots in UEFI mode and you have installed Arch in non-UEFI mode (EDIT: I think).

You should either re-install a UEFI system or convert your current box.

The Windows-generated EFISYS partition (/dev/sdb2) should be shared and mounted to /boot (or /boot/efi) in Arch.

Just to note, you should always include the exact commands used (and their verbatim output) rather than posting a vague description of the commands used.
