New installation of Manjaro XFCE to its own hdd

This is my post from May 2019 pulled form old Newbie Corner.
I added a 500GB HDD to my desktop computer and installed Manjaro XFCE on it, the installation set up ask where to put GRUB bootloader I selected the same 500GB hdd I installed Manjaro on. I have Windows 10 installed on a 250GB ssd and two storage hard disk drives. When I turn on my computer, I hit the F11 key for boot menu and select the 500GB hdd to boot from for my Linux, or my 250GB ssd to boot Windows 10. I have not had any problems running both operating systems on the same desktop pc. Since I am new to using Linux, I wanted to know if it is ok to do it this way since I have seen so much talk about running two OS’s on the same pc and dual booting. I no this may be a silly question for most of you, but I need to know if my setup is ok. Thanks for any help. I also did the inxi -Fxz command and copied and pasted the information below as was recommended when asking a question.

If you see anything that needs fixed let me know. Preformatted text

If it work for you, then is the right way.
Let say that the usually way is using grub to choose between SO not bios.
Try in manjaro terminal this
sudo update-grub

See if it show your win system

you should add
in file /etc/default/grub

sudo nano /etc/default/grub 
sudo update-grub

You should format the inxi text with the </> button in the toolbar.
