After update GRUB and rEFIND no longer recognizes my root partition

The issue started off with GRUB giving me this error

-

ERROR: device 'UUID=uuid of root parition' not found.

Skipping fsck. mount: /new_root: can't find UUID=uuid of root partition.

you are now being dropped into an emergency shell.

sh: can't access tty; job control off.

-

The fstab matches the UUID in  lsblk -f and all other connections but it still doesn't recognize my /root partition

Looking around for solutions I got rid of GRUB and replaced it with rEFIND and I still get the same error.

What can I do to get my bootloader to recognize my system and boot again?

That's because the problem occurs in the initramfs environment, it doesn't have anything to do with the bootloader.

Give us your /etc/mkinitcpio.conf, /etc/fstab and /etc/default/grub.

Finally add these values to your kernel parameters to get debug output for the initramfs:
Code: [Select]
rd.debug rd.log=all

I don't have GRUB anymore but here's the contents of fstab and mkinitcpio, I've removed the UUID for fstab but it's there.

# /etc/fstab: static file system information.
#
# Use 'blkid' to print the universally unique identifier for a device; this may
# be used with UUID= as a more robust way to name devices that works even if
# disks are added and removed. See fstab(5).
#
# <file system>             <mount point>  <type>  <options>  <dump>  <pass>
UUID=                                     /boot/efi      vfat    umask=0077 0 2
UUID=                                     /              ext4    defaults,noatime 0 1
tmpfs                                     /tmp           tmpfs   defaults,noatime,mode=1777 0 0

# vim:set ft=sh
# MODULES
# The following modules are loaded before any boot hooks are
# run.  Advanced users may wish to specify all system modules
# in this array.  For instance:
#     MODULES=(piix ide_disk reiserfs)
MODULES=""

# BINARIES
# This setting includes any additional binaries a given user may
# wish into the CPIO image.  This is run last, so it may be used to
# override the actual binaries included by a given hook
# BINARIES are dependency parsed, so you may safely ignore libraries
BINARIES=()

# FILES
# This setting is similar to BINARIES above, however, files are added
# as-is and are not parsed in any way.  This is useful for config files.
FILES=""

# HOOKS
# This is the most important setting in this file.  The HOOKS control the
# modules and scripts added to the image, and what happens at boot time.
# Order is important, and it is recommended that you do not change the
# order in which HOOKS are added.  Run 'mkinitcpio -H <hook name>' for
# help on a given hook.
# 'base' is _required_ unless you know precisely what you are doing.
# 'udev' is _required_ in order to automatically load modules
# 'filesystems' is _required_ unless you specify your fs modules in MODULES
# Examples:
##   This setup specifies all modules in the MODULES setting above.
##   No raid, lvm2, or encrypted root is needed.
#    HOOKS=(base)
#
##   This setup will autodetect all modules for your system and should
##   work as a sane default
#    HOOKS=(base udev autodetect block filesystems)
#
##   This setup will generate a 'full' image which supports most systems.
##   No autodetection is done.
#    HOOKS=(base udev block filesystems)
#
##   This setup assembles a pata mdadm array with an encrypted root FS.
##   Note: See 'mkinitcpio -H mdadm' for more information on raid devices.
#    HOOKS=(base udev block mdadm encrypt filesystems)
#
##   This setup loads an lvm2 volume group on a usb device.
#    HOOKS=(base udev block lvm2 filesystems)
#
##   NOTE: If you have /usr on a separate partition, you MUST include the
#    usr, fsck and shutdown hooks.
HOOKS="base udev autodetect modconf block keyboard keymap filesystems fsck"

# COMPRESSION
# Use this to compress the initramfs image. By default, zstd compression
# is used. Use 'cat' to create an uncompressed image.
#COMPRESSION="zstd"
#COMPRESSION="gzip"
#COMPRESSION="bzip2"
#COMPRESSION="lzma"
#COMPRESSION="xz"
#COMPRESSION="lzop"
#COMPRESSION="lz4"

# COMPRESSION_OPTIONS
# Additional options for the compressor
#COMPRESSION_OPTIONS=()

Trying to install grub again. I get this error, I think my EFI directory is bugged anyone got any ideas?

Installing for x86_64-efi platform.
grub-install: error: cannot find EFI directory.

The UUID is messed up nvm I was right. No idea what to do with this, is there some way to generate a new UUID or something?

By blanking and removing the UUID's you prevent the actual comparison of them. I can't see that sharing them is a security issue.

Try using a live cd/usb and seeing if you can mount your root partition.
If not I guess you have a corrupted filesystem.

If you can mount it then chroot into it and try to rebuild initramfs
Code: [Select]
sudo mkinitcpio -p linux

Did you install with calamares?

My bet is, your fstab mounts efi too early, before the /boot or / (if boot isn't a partition).
Try putting that / entry before the /boot/efi.
