Today I installed my first Manjaro system. I am very new to linux and want to create a dual boot system with Windows 10. After successfully installing Manjaro through Architect I installed the boot loader and selected grub. Apparently it installed successfully but when I reboot my pc it just immediately boots into Manjaro with no grub screen or way of booting into Windows. My Windows and Manjaro installs are on separate sata m2 drives and not separate partitions. I tried reinstalling grub again from my Manjaro box (from my actual installation and not a live boot so I didnt chroot in). This is what happened when I reinstalled grub:
[mike@mikebox ~]$ sudo grub-install /dev/nvme0n1p1 [sudo] password for mike: Installing for x86_64-efi platform. Installation finished. No error reported. [mike@mikebox ~]$ sudo grub-install --recheck /dev/nvme0n1p1 Installing for x86_64-efi platform. Installation finished. No error reported. [mike@mikebox ~]$ sudo update-grub Generating grub configuration file ...

After I rebooted the same thing happened, straight back into Manjaro, no grub screen. The following is what my lsblk looks like
NAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINT sda 8:0 0 1.8T 0 disk ├─sda1 8:1 0 16M 0 part └─sda2 8:2 0 1.8T 0 part nvme0n1 259:0 0 465.8G 0 disk ├─nvme0n1p1 259:2 0 512M 0 part /boot/efi └─nvme0n1p2 259:3 0 465.3G 0 part / nvme1n1 259:1 0 465.8G 0 disk ├─nvme1n1p1 259:4 0 529M 0 part ├─nvme1n1p2 259:5 0 99M 0 part ├─nvme1n1p3 259:6 0 16M 0 part └─nvme1n1p4 259:7 0 465.1G 0 part
sda is just a big empty data drive.
nvme0n1 is my manjaro drive (where root and boot are installed)
nvme1n1 is the windows disk drive.
It looks like grub doesnt know what to do with nvme1n1 or how to probe it.
So why am I currently not seeing Grub and just going straight to Manjaro (is it because only Manjaro is available?).
What do I need to do to get it to detect the windows drive to allow dual boot?
