After upgrade to ubuntu 23.10 from 23.04: ALERT! UUID=xxxx does not exist. Dropping to a shell!
Once I upgraded from Ubuntu 23.04 to 23.10 and I Can’t boot to it anymore!
Gave up waiting for root device. Common problems:
- Boot args (cat /proc/cmdline)
- Check rootdelay= (did the system wait long enough?)
- Check root= (did the system wait for the right device?)
- Missing modules (cat /proc/modules; ls /dev)
ALERT! UUID=c0fc479f-b1cc-4e85-962b-43a72eec9e91 does not exist. Dropping to a shell!
BusyBox v1.36.1 (Ubuntu 1:1.36.1-3ubuntu1) built-in shell (ash)
Enter 'help' for a lost of built-in commands.
(initramfs)
I maked sure that in the BIOS settings the Sata opration in the system configration is AHCI not RAID
I am currently running ubunut on live usb. I changed the UUID in the /etc/fstab file to ‘dev/sdb5’. and update-grub and reboot but nothing changed!
/etc/fstab:
GNU nano 7.2 /etc/fstab
# /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).

OMG, I fixed it!!
First of all, I don’t really know what exactly the problem was. However, I found that the EFI partition might be corrupted. I followed these steps to fix this (And I think this can solve most boot problems like this).
Here is my recipe to solve most of the booting problems:
1) Create a boot-repair USB:
some Linux distros do not support boot-repair like Ubuntu 23 so it’s a good idea to create your boot-repair disk
- (Download the ISO file boot-repair-64bit-iso OR boot-repair-32bit-iso)
- Burn it on USB or CD using Rufus on Windows or startup disk creator on Ubuntu (or any similar).
2) Boot to the live boot-repair USB
It’s a modified Lubuntu distro that contains a boot-repair tool and some other tools fixing other booting problems.
Run the boot-repair tool and click recommended repair. This Can solve most of the problems. If this didn’t solve your problems please continue reading.
3) Clear everything
-
here you should format the EFI partition as it might be corrupted (like in my case) (you can use the GParted tool already installed in the boot-repair live USB.
-
Now You can recreate this EFI partition using this way Or you can regenerate it using Windows USB (If you have Windows dual booted with Ubuntu) for UFEI MBR
-
In case you restored it using the Windows USB method and restored the Windows EFI partition you will be able to boot to your Windows once you boot to it open the cmd and administrator and run these commands:
bcdedit /set {bootmgr} displaybootmenu yesbcdedit /set {bootmgr} path EFIubuntugrubx64.efi -
Delete these files (or take them as backups):
etc/default/grubboot/grub/grub.cfg -
Check the `etc/fstab’ file and make sure that no errors in it. You can take a look at this question here and there are a lot of topics online about how to fix the broken fstab file.
-
run these commands to mount and chroot your Ubuntu in the live USB terminal but replace the sdb5 with the partition where your Ubuntu is installed on.
sudo mount /dev/sdb5 /mnt && mount --rbind /dev /mnt/dev && mount --rbind /proc /mnt/proc && mount --rbind /sys /mnt/sys && chroot /mnt bash -
Now run this command to regenerate ‘etc/default/grub’ file:
sudo apt-get remove --purge grub-pc && apt-get install grub-pc -
and then
update-grub
4) Run the boot-repair tool again
here everything should work very well.:)
