Failed to mount /boot/efi. Dependency failed for Local File Systems.

Hello,

I just put in a new nvme ssd into my system so and i figured I should also (randomly) update my bios (msi b450 tomahawk max). So i did that and grub disappeared from the bios bootloader. Fired up systemrescue and reinstalled grub according to chatgpt's instructions.

Then i tried to boot into arch and was met by this error saying I am in emergency mode. I have no idea what's happening, any help would be apprewciated.

Heres some of info that chatgpt was asking for
lsblk:

perhaps its something to do with my fstab? i dont know chatgpt told me to modify it
this is my fstab

Major, major mistake right there. Don't trust anything ChatGPT tells you. Follow the wiki.

Where did you have the ESP mounted when you reinstalled GRUB? How, exactly, did you reinstall it?

Re: Failed to mount /boot/efi. Dependency failed for Local File Systems.

hello thanks for the reply.
Yeah i get that, but i am pretty experienced with arch and i know when its talking shit... but youre probably right

The ESP was mounted in the live SystemRescue usb. This was the mount process

mount /dev/sda3 /mnt/linux/boot/efi

and other relevant mounts:

mount --bind /dev /mnt/linux/dev
mount --bind /proc /mnt/linux/proc
mount --bind /sys /mnt/linux/sys
mount --bind /run /mnt/linux/run
mount -t efivarfs efivarfs /mnt/linux/sys/firmware/efi/efivars
chroot /mnt/linux

i then used

grub-install --target=x86_64-efi --efi-directory=/boot/efi --bootloader-id=GRUB
grub-mkconfig -o /boot/grub/grub.cfg

i was then able to get into grub.
the issue of the error booting into linux remains.

however launching windows from grub works, if that's noteworthy.

Re: Failed to mount /boot/efi. Dependency failed for Local File Systems.

update --

i chrooted into my root partition (dev/sda1) and I did

yay -Syu
and pacman -S linux-zen linux-zen-headers

I tried booting up my install and the old error went away and it is now:
"Failed to mount /dev/sdb1"
"Dependency Failed for local file system"

Issue with the kernel? Fstab now not working? i'll remove the fstab entry for my sdb1 device and see what happens
