    I'm trying to install the latest version of Elementary OS (5.1.5) alongside Windows 10 and Ubuntu 20.04. I created an empty partition (ext4 format, logical partition + swap) - everything goes smoothly until the reboot: no eos shown and the system boots to Ubuntu, as usual. What am I doing wrong?
    Any hint?

    Could you give a little more information for troubleshooting, it would be helpful to know your partitions table and grub.conf.
    When using the ElementaryOS or Ubuntu, paste the output of the following commands into this forum.

    Code (Text):
    sudo fdisk -l
    (Lists out your current disk partitions)

    Code (Text):
    cat /boot/grub/grub.conf
    (Displays your current grub configuration)

    Thank your for helping me with this.
    Regarding the fdisk -l command, the output is quite large, but the part you are probably interested in is the following one:

    Disk /dev/sda: 238,49 GiB, 256060514304 bytes, 500118192 sectors
    Disk model: SAMSUNG MZNLN256
    Units: sectors of 1 * 512 = 512 bytes
    Sector size (logical/physical): 512 bytes / 512 bytes
    I/O size (minimum/optimal): 512 bytes / 512 bytes
    Disklabel type: gpt
    Disk identifier: BC2BF41F-498C-47F1-AC38-EB8371C5D080

    As you can see, elementary os entry is missing in the boot file configuration, although no error was displayed during the installation.
    Any help welcome.

    Hi AAZZ,

    Looking at your grub.cfg there seems to be no entry for "elementaryOS" that's why it's not showing up as an option.
    (the "menuentry" sections in your grub.cfg file indicate what OSes it has as options)

    You can double check this with
    Code (Text):
    cat /boot/grub/grub.cfg | grep "menuentry"
     
    Also you mentioned you created a blank partition /dev/sda8 for elementaryOS.

    Sorry for the silly question on my part, but you did install elementaryOS? not just run it from the bootable USB?

    Assuming you did, can you also confirm that the /boot/grub/grub.cfg file we're looking at is the ubuntu one or the elementaryOS one?

    Now this is where things get a little bit tricky. we need to add elementaryOS to the grub.cfg file. Unfortunately where I am it's very late and I'm not able to talk through it at the moment, but hopefully someone else on this forum can help

    Thank you for time and for your kind help.
    As you can see, /dev/sda8 is the partition where I installed ElementaryOS (yes, I did install it with no error messages during the installation). I created an ext4 partition where eOS was installed and mounted (/ mount point), but as I can see, this configuration was not kept and the mounting point (/) is /dev/sda7 (ubuntu partition).
    I can confirm that the /boot/grub/grub.cfg file is the ubuntu one.
    Some people suggest that it might have to do with the partition type, that is, a primary partition is preferred over a logical one. However, I recently installed eOS on my old Acer laptop (same configuration: WIN 10 + UBUNTU 20.04 + eOS) and everything went smoothly and the system installed properly...

    SOLVED!
    It seems that the problem has been solved by the last Ubuntu update, now eOS is visible at booting, so no problem anymore.
    Thanks for your help!
