[SOLVED] Unable to boot (Timed out waiting for device /dev/.uuid)

Hi! I am trying to install arch for the first time, and have followed the installation guide as closely as I could. When I finally try to boot (using either linux or linux-lts), the following happens:
(Note: A string that looks like a UUID prepended with a filled-in square character appears throughout this, which I will refer to as {UUID})

The following displays in sequence:

Loading Linux linux-lts ... (or just "Loading Linux linux ..." if i choose linux)
Loading initial ramdisk ...

After a delay, the following displays:

[  TIME  ] Timed out waiting for device /dev/{UUID}
[DEPEND] Dependency failed for File System {UUID}
[DEPEND] Dependency failed for /sysroot
[DEPEND] Dependency failed for Intrd Root File System
[DEPEND] Dependency failed for Mountpoints Configured in the Real Root
[DEPEND] Dependency failed for Intrd Root Device
You are in emergency mode. After logging in, type "journalctl -xb" to view
system logs, "systemctl reboot" to reboot, or "exit"
to continue bootup

Cannot open access to console, the root account is locked.
See sulogin(8) man page for more details.

Press Enter to continue

Upon pressing enter, the following displays in sequence:

Reloading system manager configuration.
Starting intrd.target

After a delay, the following again appears:

You are in emergency mode. After logging in, type "journalctl -xb" to view
system logs, "systemctl reboot" to reboot, or "exit"
to continue bootup

Cannot open access to console, the root account is locked.
See sulogin(8) man page for more details.

Press Enter to continue

I'm not sure how to retrieve any logs in this situation. Any help is appreciated!

You may have entered the UUID incorrectly while entering it into the boot loader config. Make sure you are entering the UUID of the root partition obtained from lsblk -f (or any other similar command).
Tip: Use the kernel parameter: SYSTEMD_SULOGIN_FORCE=1 to unlock the console, mount the root partition manually to /sysroot and exit to temporarily boot into your system.

What did you install on? If it uses UFS, mkinitcpio doesn't currently include the necessary module (fixed but not released: https://gitlab.archlinux.org/archlinux/ … cafe5d0de8 ) If that's not it, post your bootloader config, it sounds like you're using GRUB?

Re: [SOLVED] Unable to boot (Timed out waiting for device /dev/.uuid)

I am using an Ideapad Slim 3 15IAN8, which does apparently use UFS. I’m not quite sure how to implement this fix, though. I tried adding “ufs” to the modules array in /etc/mkinitcpio.conf and running “mkinitcpio -P” again (all while chrooted into the new root directory), but that didn’t change anything. I am using GRUB. Upon removing quiet from the linux command(?), the error changes to
[ TIME ] /dev/disk/by-uuid/{uuid}

Apologies, I should have looked a little harder. I followed the steps shown here (https://belkast.com/posts/linux/ufs/ ) and now I can boot into my system! Yay! Thanks for the support!
