Grub finding wrong disk

Hello everyone. I have installed ArchLinux version <your_version_of_ArchLinux_here> on a Hard Disk Drive with LUKS encryption. I have manually created and encrypted partitions with cfdisk and cryptsetup. Then i installed ArchLinux.

My partitions:

1. BOOT partition 8G /dev/sda1

2. Encrypted SWAP partition 8G crypto_LUKS /dev/sda2 i mount SWAP with keyfile /mnt/keys/swapenckeyfile

3. Encrypted ROOT partition 98.6G crypto_LUKS /dev/sda3 i mount ROOT with password

I am unable to boot into anything else than emergency shell and on every boot i receive the following error messages:

result by running lsblk:

/etc/mkinitcpio.conf

# 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 filesystems keyboard fsck)

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

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

Re: Grub finding wrong disk

Post details of your partition table, and relevant configs (grub, mkinitcpio, crypttab etc).

Moving to NC...

Re: Grub finding wrong disk

Read the Code of Conduct and only post thumbnails http://wiki.archlinux.org/index.php/Cod … s_and_code

No body is helping...

And don't bump: https://wiki.archlinux.org/index.php/Co … ct#Bumping

Nobody is helping because you haven't provided the information you were asked for. The error is pretty clear: you have the wrong UUID in your boot loader/manager. But without that config, and your mkinitcpio.conf, we are all just guessing.

I've add the file you need, just want to make sure do you meant mkinitcpio.conf for mkinitcpio?

Also I can't find the file grub under /etc (I've copy whole directory out), there is /etc/grub.d but can't sure which file do you need an you give me the real path for the grub file?

Re: Grub finding wrong disk

/boot/grub/grub.conf and output of "fdisk -l /dev/sda" as well as "lsblk -f"

How exactly did you install archlinux?

Re: Grub finding wrong disk

/boot/grub/grub.conf

I think you mean /boot/grub/grub.cfg ?

Re: Grub finding wrong disk

There should be a fixed convention for suffixes ;-)
(Ie. "yes, of course")

We did one better, we have several of them.
