  1. [SOLVED] Re: Struggling to install Ubuntu 20.04 LTS to newly built PC

    Do not recommend MBR(msdosl) & BIOS boot, but if it works for you that is ok.

    Took a bit, but glad you got it working.
  3. [SOLVED] Re: Struggling to install Ubuntu 20.04 LTS to newly built PC

    I expect you can plug in Windows NVMe and update grub.

    Only issue may be if drive 0 & drive 1 get changed. Not sure how two NVMe drives are ordered in UEFI.
    With SATA it is port order and...
  4. [SOLVED] Re: Struggling to install Ubuntu 20.04 LTS to newly built PC

    If you are getting grub> can you manually boot?

    First try:
    configfile (hd0,2)/boot/grub/grub.cfg

    Or:
    set prefix=(hd0,2)/boot/grub
    set root=(hd0,2)
    linux (hd0,2)/boot/vmlinuz root=/dev/sda2...
  5. [SOLVED] Re: Struggling to install Ubuntu 20.04 LTS to newly built PC

    If you got a grub menu, you are booting.

    And you had working entry before. Not sure what re-running Boot-Repair did.
    And I still do not understand the failed to register EFI boot entry, but more...
  6. [SOLVED] Re: Struggling to install Ubuntu 20.04 LTS to newly built PC

    I did not think nomodeset was required with AMD, but I used to have nVidia, but now only use the Intel Chips's video (as it was better than my old nVidia card). Not really up to speed on AMD video,...
  7. [SOLVED] Re: Struggling to install Ubuntu 20.04 LTS to newly built PC

    Everything Boot-Repair is showing is correctly.
    You have a new ubuntu entry in UEFI using GUID/partUUID of the new ESP to find shimx64.efi.
    You have grub.cfg in ESP that configfile entry is to...
  8. [SOLVED] Re: Struggling to install Ubuntu 20.04 LTS to newly built PC

    All that looks correct to me.
    Good luck, I expect install to work.
  9. [SOLVED] Re: Struggling to install Ubuntu 20.04 LTS to newly built PC

    Samsung has firmware updates on its site.
    My Samsung NVMe drive has a specific ISO just for update of my model in its support section.
    I think with Windows it has an application, but could not get...
  10. [SOLVED] Re: Struggling to install Ubuntu 20.04 LTS to newly built PC

    Sounds like some setting in UEFI.
    I would review manual on NVMe drives.
    Many NVMe drives conflict with a SATA drive port so you cannot use some ports when using NVMe.
    Perhaps a Boot setting, but...
  11. [SOLVED] Re: Struggling to install Ubuntu 20.04 LTS to newly built PC

    I just showed the NVMe drive's partUUID, that was not a boot entry.

    0007 would be one of the ubuntu entries you should see in your UEFI as a boot option.
    Often not clear which entry is which when...
  12. [SOLVED] Re: Struggling to install Ubuntu 20.04 LTS to newly built PC

    Anytime you boot into Windows it may do an update.
    And many Windows updates turn fast startup back on.

    I often have to click on text I copy from my Zim file that is after a link and click on...
  13. [SOLVED] Re: Struggling to install Ubuntu 20.04 LTS to newly built PC

    Yes.

    Try the install of the UEFI boot entry using efibootmgr before running Boot-Repair.
    And post any error messages.

    Boot-Repair is complaining you have /target still mounted which is part of...
  14. [SOLVED] Re: Struggling to install Ubuntu 20.04 LTS to newly built PC

    Lets delete these entries. Do not think it will solve any of the issues. But may avoid confusion on which Ubuntu entry is correct.

  15. [SOLVED] Re: Struggling to install Ubuntu 20.04 LTS to newly built PC

    If you use gparted to change it, then it is erased & you have to reinstall
    It is possible to convert in place, better for data only drives.
    But you can then a full reinstall grub & update any...
  16. [SOLVED] Re: Struggling to install Ubuntu 20.04 LTS to newly built PC

    You never changed your second NVMe drive to gpt.



    And your UEFI boot entries show MBR, which you can delete with efibootmgr.

  17. [SOLVED] Re: Struggling to install Ubuntu 20.04 LTS to newly built PC

    Post a new link from Boot-Repair for its report.
  18. [SOLVED] Re: Struggling to install Ubuntu 20.04 LTS to newly built PC

    I think the reinstall of grub, will use the mount in the fstab of the ESP as where to reinstall grub.
    And then because that does not exist, it gives the error.

    Try changing the UUID of the mount...
  19. [SOLVED] Re: Struggling to install Ubuntu 20.04 LTS to newly built PC

    That shows an Ubuntu UEFI boot entry in the same ESP as Windows.
    This is the GUID/partUUID that the ESP on Windows drive has.
    1e5db068-d49d-407d-9349-2d7fbcdfd6e3

    You can see that with:

  20. [SOLVED] Re: Struggling to install Ubuntu 20.04 LTS to newly built PC

    Those errors sound like they are from efibootmgr not being able to write into your UEFI.
    Do you have some setting that locks UEFI entries? May be a separate security setting whether UEFI Secure Boot...
  21. [SOLVED] Re: Struggling to install Ubuntu 20.04 LTS to newly built PC

    Do you have latest firmware on your NVMe drives.
    I have a Samsung NVMe drive and updated by downloading a bootable ISO that was just for my model. I think for Windows Samsung has an application for...
  22. [SOLVED] Re: Struggling to install Ubuntu 20.04 LTS to newly built PC

    I have seen users install to MBR(msdos) partitioned drives in UEFI mode, but drive really should be gpt partitioned.

    Change to gpt and try again.

    Windows only installed to gpt with UEFI.
    I do...
  23. [SOLVED] Re: Struggling to install Ubuntu 20.04 LTS to newly built PC

    Moved to Mint sub-forum as not sure what changes to standard Ubuntu they make.

    If reinstalling grub from live installer you typically have to mount the ESP & / and other system partitions, if you...
  24. [SOLVED] Re: Struggling to install Ubuntu 20.04 LTS to newly built PC

    Sounds about right.

    I normally check mounts before I start. Then as password screen as by then it has added the required mounts. And that is where I change it.

    From one of my installs:

  25. [SOLVED] Re: Struggling to install Ubuntu 20.04 LTS to newly built PC

    Did you check what mount the installer had?
    And was the partition you mounted flagged as an ESP?

    And if install otherwise completed, you often can just use Boot-Repair to install/reinstall grub.
