    Operation System not found - Ubuntu 24.04.1 LTS fresh Install on Inspiron 14R N4110

    Hi,
    Please help. I tried
    https://help.ubuntu.com/community/BootPartition
    but that did not work.

    Here is the paste from boot-repair app
    https://paste.ubuntu.com/p/j372FqcC9h/

    Many thanks

    UPDATE: A solution is to choose dual boot (Win+ Ubuntu) option during the installation. See post#22 for more details.

    Line 283 - The firmware seems EFI-compatible, but this live-session is in Legacy/BIOS/CSM mode (not in EFI mode).

    You have installed in old style Legacy mode.
    As your PC seems to be UEFI compatible, I would suggest that you re-install in UEFI mode.
    Your disk is already GPT, which is fine (see line 291)
    Fresh install indicates that there should not be any data to backup?

    You may be better off with Xubuntu or Lubuntu with a 2nd Gen Intel Processor.

    Thanks for your reply. For some reason, my 2011 laptop cannot read USB image built with Rufus' GPT partition scheme; I get "Operation System not found" error. It only boots with MBR (Legacy?).
    To make sure it's not an Ubuntu issue, I also tried with Windows image and experienced the same problem - cannot boot with GPT image.
    I did update the bios using latest version (A12) from Dell's website but that did not add anything new to the laptop's boot menu, except it changed the version number from A10 to A12.

    Yes fresh install indicates no data to backup. Since it's painfully slow to run Win10 on this laptop, I wonder if a fresh install of Ubuntu could help to speed it up. This is not my main computer for daily use. I only want to use it when travel.

    Thanks for the Xubuntu and Lubuntu suggestion, I'll check out both.

    Your internal disk is already GPT, so I don't think it matters about the Rufus configuration.
    When you boot the USB, does your PC show two options similar to attached image?

    No, nothing likes your attached image.

    If I remember correctly, I got something similar to this (I downloaded this image from the web. I don't think there was an OEM Install option in my case)

    Ah, a little misunderstanding in play here.
    Your image is the grub menu after booting the usb.

    I was referring to the PC boot menu using the dedicated key (F2, F9, F10 or similar)
    i.e. before booting into a live session.
    This allows you choose UEFI or Legacy boot mode.
    Boot in UEFI mode = Install in UEFI mode

    Sorry, my bad. There is no such option. Here are the images from my boot (F2) screen.

    Older systems even with SSD work much better with a lighter weight flavor.
    https://ubuntu.com/download/flavours
    Light weight flavors:
    Lubuntu, Xubuntu, Ubuntu MATE, Budgie
    Flavors of Ubuntu only come with three years of supported life (five years applies to Ubuntu Desktop, Ubuntu Server but not flavors)

    I use Kubuntu which is more of a mid-weight flavor on both newer laptop & very old laptop.
    Old laptop would not even install Ubuntu, was a bit surprised that Kubuntu installed. But it still was slow as old HDD was slow & it had little RAM.
    But needed Old laptop for a trip when new laptop was in for repairs. I also had full UEFI install of Kubuntu on external SSD. Found I could add grub BIOS boot stanza on HDD to boot external SSD, bypassing UEFI, and directly booting kernel, and it worked well. Faster swap on SSD helped to make up for low RAM, but I still tried not to load too many apps at once.

    That's a pity, no sign of UEFI in your images.

    One last double check
    Can you attach your USB, power on and press F2 and see if you have more than one entry under USB or Removable Drive?

    I might have found something here.
    My laptop has an INTEL processor but the iso image I downloaded from
    https://ubuntu.com/download/desktop#...ts-NobleNumbat

    indicated it was for an AMD cpu:
    https://ubuntu.com/download/desktop/...amd64&lts=true

    Could that be my problem? If yes, where could I find an Ubuntu 24.04.1 LTS iso for Intel processor?

    The lubuntu website
    https://lubuntu.net/
    has 2 downloads: one for INTEL and the other for AMD.

    Thank you.
