    Dual boot fails

    Configuration - Dual boot
    SSD 240G - Ubuntu 16.04
    SSD 1TB -Ubuntu 16.04
    WD 1TB - for storage
    WD 2TB - for storage

    After changing SSD 1TB to a new SSD 2TB - Ubuntu 16.04, dual boot failed. It always boots SSD 2TB even selecting to boot SSD 240G.

    To boot SSD 240G I have to unplug the cables of SSD 2TB.

    Please advise how to check and to sort out this problem.

    Thanks in advance

    Re: Dual boot fails

    May be best to see details, use ppa version with your live installer (2nd option) or any working install, not older Boot-Repair ISO:
    Please copy & paste link to the Boot-info summary report ( do not post report), the auto fix sometimes can create more issues.

    Thanks for your advice.

    I'll follow the 2nd option: install Boot-Repair in Ubuntu
    https://help.ubuntu.com/community/Boot-Repair

    Code:
    sudo add-apt-repository ppa:yannubuntu/boot-repair
    sudo apt-get update
    sudo apt-get install -y boot-repair && boot-repair
    Do I need to disconnect both SSDs ? I have important data on SSD 2TB and the storage WD disks.

    Thanks

    You need to download and run the boot repair software as instructed and select the Create BootInfo Summary option. Do NOT try to make any repairs. You will need both drives attached to get accurate and complete information. The software gathers information only and will give you a link to post here when finished. No changes will be made unless you tell it to so make sure you ONLY run the Create BootINfo Summary option.

    Hi,

    Thanks for your advice,

    I'll run an USB booting the desktop PC and install Boot-Repair on the USB terminal.

    If I understand your advice correctly. After starting the Boot-Repair software selecting "Create BootInfo Summary option" and continue ?

    Are following video relevant to my case?

    I am not a fan of videos as you cannot copy & paste. They often go by too fast to use to actually do what they show.
    But the video gives you an idea of what you will see.

    Your attached screen shot is part of first link to how to install Boot-Repair & its screenshot.

    Hi,

    Thanks for your advice. I have new discovery as follow.

    Now I have 2 SSD disks connected and boot SSD1(2TB). It seems to me that SSD2(240G) is not mounted automatically at boot. Nor I can find it on the left vertical menu bar.

    Re: Dual boot fails

    Many SSD particularly NVMe drives have needed firmware updates, even if new, to work in Linux.
    Have you checked to see if you have latest firmware in your SSDs.
    You probably should also make sure UEFI is the most current version available.

    How to check firmware in SSDs ?

    I don't think the SSD in question is a NVMe drive.

    Edit
    ===
    The firmware version of SSD1 (2TB)
    ⟫ sudo smartctl --xall /dev/sda | grep -i firmware
    Code:
    Firmware Version: RVT01B6Q
    The firmware version of SSD2 (250G)

    ⟫ sudo smartctl --xall /dev/sdb | grep -i firmware
    Code:
    Firmware Version: X61110RL
    But I have no idea whether they are uptoday?

    Re: Dual boot fails

    Google tells me that Sandisk has Dashboard that includes updates. Probably only for Windows.

    https://kb.sandisk.com/app/answers/d...rt-information

    Samsung has magician, but Linux version was buried away in its commercial support area and never worked right for my older 840.
    Again Windows versions.https://www.samsung.com/semiconducto...ownload/tools/
