Lost GRUB Menu after Windows10 Install

Hello Guys,

I know Linux should be installed after installing windows, but I was using Arch as my daily driver for almost 6 months now, and I needed windows because of a company software that I had to install.
Therefore, I did.

I have Arch installed on my SSD
And I installed Windows 10 on my HDD

But apparently, Windows used the existing EFI partition on my SSD to install its bootloader and now I can't get into grub.

Even from the UEFI Menu it only shows my SSD (With Windows Boot Manager) written next to it.

Right now,
I am using a Manjaro Live USB to get into arch,
It has an option to "Detect UEFI Bootloaders" and when I select that I can find my grub menu under (gpt dev/sda1)  which then has my arch install as well as my windows. (Just like I wanted)
But I couldn't possibly always carry around the USB to boot into Arch.

Any help guys?

Rerun the appropriate GRUB install command from the chroot.
