    Angry Ubuntu 24.04 UUID =/

    Hello everyone, I bought a new Asus Vivobook E1504GA. I downloaded the Ubuntu 24.04 distribution onto a flash drive, cleaned the disk through the installer and installed Ubuntu. When I try to start my laptop, I get into the BusyBox shell. How can I fix this? The commands don't work in the shell. I can boot into Live mode from a flash drive







    I would like to add that I used Boot Repair to restore the boot, but it did not give the desired result. I received a message that
    "Locked-NVram detected. Please do not forget to make your UEFI (fimware boot on the Ubuntu 24.04 LTS entry (sdb1/efi/ubuntu/grubx64.efi file)!"
    Before running Boot Repair I got this:
    https://paste.ubuntu.com/p/m2rszdY9RB/
    After launching, I received this link:
    https://paste.ubuntu.com/p/2HSJn5MM59/
    But my problem still wasn't solved.




    I'm really tired of messing around with this, so I'm asking for help. If this is necessary, I am ready to reinstall the OS according to your manual

    Re: Ubuntu 24.04 UUID =/

    BusyBox is a small form of embedded Linux. It has its own set of commands. Being dropped to a BusyBox shell usually means that something is seriously broken with the installation.

    UUID = Universally Unique Identifier. That long number represents either the drive (storage) or a partition on the drive. It could indicate that the partition that Ubuntu was installed in no longer exists.

    An install of Ubuntu should have a minimum of two partitions. A EFI System partition formatted as FAT32. That would contain the Linux (Grub) bootloader files. And a Ubuntu partition.

    You could try loading the Ubuntu Try session and running the Disks utility and reporting what partitions that utility will show you. The disks utility will also show the UUID number for each partition. That should help identify which partition is being referred two.

    It might be simpler to just re-install Ubuntu 24.04 LTS

    Now I will reinstall Ubuntu, partition the disk manually during installation and post the results. I tried this, unfortunately it doesn't help me. The UUID is the same as the disk UUID.

    Re: Ubuntu 24.04 UUID =/

    Now my disk contained 2 partitions: efi in fat32 (sdb1) and a partition with the OS in Ext4 (sdb2)

    sdb
    ├─sdb1 vfat 4B8D-B21B 41c2445f-cbf1-4867-a37a-208968222ab1
    └─sdb2 ext4 734487d2-5cfa-479e-900c-8af8ecf3ff2f 86cd840b-b35f-422f-a4a2-c8903cf691d1

    Re: Ubuntu 24.04 UUID =/

    As with many systems, your UEFI promotes flash drive to hd0 or sda.
    But when flash drive removed your internal drive becomes hd0.
    Entry in sdb's ESP shows hd1,gpt2.
    I bet if you change to hd0 it will work.

    Ignore modprobe error.
    Its trying to mount efivars in wrong place.
    If chrooting again add this line.
    mount -t efivarfs efivarfs /sys/firmware/efi/efivars
    mount shows:
    efivarfs on /sys/firmware/efi/efivars type efivarfs (rw,nosuid,nodev,noexec,relatime)

    If you're lucky you can re-order the devices in the BIOS/UEFI.

    Re: Ubuntu 24.04 UUID =/

    My BIOS does not have such a function. I can only disable or enable the disk and change the boot order of the devices.
    I can't do this by booting through a USB flash drive?
    mknod /dev/sda b 8 16; mknod /dev/sdb b 8 0
    Can't help me?

    Re: Ubuntu 24.04 UUID =/

    Its not the drive like sda once booted. It is the enumeration of the drive by UEFI/BIOS which grub has to use as drives are not yet mounted. Or hd0 or hd1.

    From live installer you should be able to manually mount the ESP and edit grub.

    You may be able to manually boot.
    Can you get grub menu by pressing escape key just after UEFI/BIOS screen? Can be quick, so sometimes have to try again. And if UEFI fast boot on, it will be too quick. Do full power shutdown & "cold" boot to get UEFI/BIOS to rescan system and give just enought time to press escape key.
    Then can you boot recovery mode?
    Or manually edit grub entry with e key.
