Can't see anything after boot?

When I boot I just see nothing and my GPU and PC is on and my monitor says input but I just see a black screen. every other thread I found about this has stuff about using grub or a terminal or something but I can’t do any of that because my screen is completely black??? Ive tried control alt F2 as well and also tried pressing every key on my keyboard it just doesn’t do anything. I seriously have no idea what to do and I’m panicking because I really really don’t wanna have to reset and reinstall my os.

There are a number of threads about how to proceed.
Here is one.

Now it’s just showing the Manjaro loading screen indefinitely.

???
What do you mean? What did you do?
We need more information to be helpful.

I booted through a USB and reinstalled GPU drivers and disabled my pcie passthrough stuff in chroot.

can you report from usb live manjaro

inxi - Fza 
sudo manjaro-chroot
mhwd-kernel -li
mhwd -li
exit ( end-chroot )

you may need to add “iommu=pt” on boot

forgot to iommu the first time

Remove all of this. (and update-grub)

Also. Please format your post.

This is strange, any idea why not a single partition has been detected? What have you tried before the issue showed up?

driver=free nouveau.modeset=1 i915.modeset=1
radeon.modeset=1

Where do I remove this from?

Also it seems I just can’t update-grub ?

[manjaro ~]# sudo update-grub
/usr/bin/grub-probe: error: failed to get canonical path of `/dev/sda1'.
[manjaro ~]# sudo grub-mkconfig =o /boot/grub/grub.cfg 
/usr/bin/grub-probe: error: failed to get canonical path of `/dev/sda1'.

No clue. I haven’t really tried anything before the issue showed up ?

I mean remove it from your boot options.
You can do this one time by hitting ‘e’ at boot …
But the permanent setting is probably stored in /etc/default/grub
(after which you would update-grub)
But…

Thats a problem. Lets maybe fix that first.

What is the output of

lsblk && cat /etc/fstab

I did check /etc/default/grub but I wasn’t able to find it anywhere there.

What is the output of

sudo fdisk -l

I guess you need to re-install grub as explained here, use the BIOS System method:

/dev/sdy

in the description has to be replaced with your primary disk, most likely

@akqua
You might need to be more specific about when you are showing details.
The fstab and lsblk you shared were from the live usb environment so they dont help in relation to your other problems … I dont know if its the same for your update-grub issue as well.

so far I’ve run everything inside manjaro-chroot

Did you try to restore grub as proposed?

yeah. now when I boot up without the USB it’s showing me a rootfs terminal thing

/dev/sda1 contains a file system with errors, check forced. Inode 29889647 extent tree (at level 2) could be narrower. IGNORED. Unattached inode 36992785

/dev/sda1: UNEXPECTED INCONSISTENCY: RUN fsck MANUALLY. (i.e., without -a or -p options)

ERROR: Bailing out. Run 'fsck UUID=e7eb13ec-3824-4fe6-a5b4-c62d1b9cbbfc' manually 
********** FILESYSTEM CHECK FAILED **********

Please run fsck manually. After leaving this maintenance shell, the system will reboot automatically.

sh: can't access tty: job control turned off [rootfs 18

so I ran fsck UUID=e7eb13ec-3824-4fe6-a5b4-c62d1b9cbbfc manually and now I see a grey screen that just says …

Oh it just stopped doing that and I’m back in now I suppose?

could someone please explain wtf I just witnessed in case it happens again?

Looks you had a filesystem error which could be fixed using fsck command. Probably solved in combination with restoring grub.
