Well I'm using the same 64-bit installer from the official site along with a few tweaks that I've read in FGO reddit. That allows me to unroot the system while enabling access to my HDD drives like a rooted device. FGO won't run on root afterall.

Link to the FGO reddit guide: https://www.reddit.com/r/grandorder/comments/63scjr/installing_remix_os_then_unrooting_it_for_playing/?st=j2fnn0el&sh=0d6e0aae

Also, I'd recommend you uninstall Remix first and start from scratch.

Here's the Steps I followed in the comment.

Use a partition tool to do your job, there are a lot out there. Changing your drive type from primary to logical still works, because usually that's the easiest way of separating space from a drive into a standalone one. I recommend AOMEI, it's more user-friendly than the default windows one and usually works.

Extract it and run the .exe installer, and follow the steps. Make sure to select the install option as "Hard Drive" and not anything else. Use the drive you just created as well (I recommend giving it 20GB space, explanation down below)

Once it's finished installing, do not restart right away. Go into X:\RemixOS (X is obviously where you installed your RemixOS), find menu.lst, open it up with Notepad or something similar. Add the following entry on top of those already available:

title Resident mode system_dev find --set-root /RemixOS/kernel kernel /RemixOS/kernel root=/dev/ram0 SERIAL=random logo.showlogo=1 androidboot.selinux=permissive quiet SRC=RemixOS/ DATA= CREATE_DATA_IMG=1 REMOUNT_RW=1 initrd /RemixOS/initrd.img boot

This entry will basically create a system_dev.img partition and mount it as R/W so you can unroot inside RemixOS and still browse root with a file explorer in case you need something with it later. Why do I do this? Because it leaves your system.sfs intact so if you screw something up you could just delete that system_dev.img and create a new one with said boot option. But of course it'll take extra space.

Restart, boot into RemixOS with the first option, it will do its thing, and then after you're finally in, here's how to unroot RemixOS easily: just download Root Browser, get into \system\bin and \system\xbin and delete the 2 su files there, leave busybox intact. Restart. Don't use SuperSU, it's wonky and usually doesn't work, because there's already a Superuser entry available inside RemixOS and those two conflict.

You're done.
