Installed Zorin 17.2 Core will run from USB but not from disk. Busybox error - see details below

Can you type

exit

at the prompt and relay what it says?

It just repeats the message shown in my initial post.

My fault. I failed to read the output in your screenshot.

Are you set to RAID instead of AHCI?

Are you using UEFI or MBR (Legacy) boot?

Pretty sure AHCI and definitely UEFI

There are quite a few things we could troubleshoot:

  • Kernel
  • fstab
  • S.M.A.R.T. test on drive

But if this is a Fresh Install, I would first just try reinstalling Zorin OS. It only takes about an average of 25 minutes to install and if there is any corruption with any of the above, that should fix it.

OK. Thank you I'll let you know how it goes.

As Zorin 17 is a fork of Ubuntu 22.04 my Brave A.I. search via mojeek comes up with:

UUID Does Not Exist Error

When encountering the “ALERT! UUID=xxxx does not exist. Dropping to a shell” error after installing Ubuntu 22.04, it often indicates that the system is unable to find the specified UUID for the root filesystem. This can be due to several reasons, including incorrect UUIDs in the /etc/fstab file, issues with the partition table, or problems with the bootloader configuration.

Here are some steps to troubleshoot and potentially resolve the issue:

  1. Boot from a Live USB: Use a live USB to boot into Ubuntu and access the installed system.
  2. Check UUIDs with blkid: Run the blkid command to list all the UUIDs of the partitions on your system. Compare these with the UUIDs in /etc/fstab to ensure they match.
  3. Check /etc/fstab: Open the /etc/fstab file and verify that the UUIDs listed there correspond to the correct partitions. If there are discrepancies, update the file with the correct UUIDs.
  4. Update GRUB Configuration: If the UUID in the GRUB configuration file (/boot/grub/grub.cfg) is incorrect, you may need to update it. You can regenerate the GRUB configuration by running sudo update-grub.
  5. Check Partition Table: Use sudo fdisk -l or sudo parted -l to check the partition table. Ensure that the partition table is correct and that the partitions are properly formatted.
  6. Run Filesystem Check: If the partition is not recognized, you can attempt to run a filesystem check using sudo fsck /dev/sdXn (replace /dev/sdXn with your actual partition, e.g., /dev/sda1).
  7. Reinstall GRUB: If the issue persists, you might need to reinstall GRUB. Boot into the live USB, mount the root filesystem, and run the following commands:
sudo mount /dev/sdXn /mnt
sudo grub-install --boot-directory=/mnt/boot /dev/sdX
sudo update-grub

Replace /dev/sdXn with your root partition and /dev/sdX with your disk identifier.
8. BIOS Settings: Ensure that your BIOS settings are correctly configured. For example, switching from RAID to AHCI mode can sometimes resolve boot issues.

If you follow these steps and the issue still persists, it might be necessary to seek further assistance or consider a clean installation of Ubuntu.

The fresh install didn't work - all was well until I entered "Restart Computer" when the restart button greyed out and the computer stalled. I turned it off and restarted and I saw the identical Busybox error. Any thoughts?

Thank you, a clean install didn't work so I'll try your suggestions.

Welcome to the Forum!

A couple of Questions:

  • Is this a Dual-Boot System or Zorin-only?
  • If Dual-Boot: Is Fast Start-Up in Windows turned ?
  • Are Secure Boot and Fast Boot in BIOS turned off?
  • What Tool did You used for creating the bootable USB Stick?
  • Did You checked the Checksum of the ISO?

Hi. Zorin only. I have no option to turn off Secure boot in BIOS. I used Balena Etcher to create disk. No I haven't tried Checksum for ISO

Okay, here will explained how to check the Checksums and there are listed the Checksums itself at the End:

Okay, if You have a Windows Machine or the Opportunity to use one, You could try it with Rufus instead of Etcher. And because Your BIOS is in UEFI, look that You choose on ''Partition Sheme'' the GPT Option:

Tried Rufus but ended up with the same result.

Important. Please confirm you have now checked of the SHA256 checksum of the downloaded .iso .
Ponce-De-Leon (post #13) gave you a link to Zorin website information how to do that essential task.

Checksum completed and they match.

This could be caused by hardware issues. Hard drive and cables is where i'd start.
I've used below method a few times to fix a mates PC, which randomly threw up this issue.

https://ostechnix.com/how-to-fix-busybox-initramfs-error-on-ubuntu/

I just did a websearch using "missing modules (cat /proc/modules; is /dev)" as searchterm.

Found this: ubuntu - Missing modules (cat /proc/modules; ls /dev) and UUID doesn't exist in BusyBox - Unix & Linux Stack Exchange

A suggestion from the link above, is check BIOS setting for SATA configuration is AHCI.

You could maybe benefit from other searches with that searchterm as it reveals several hits on that subject.
