    In addition, I assume (?) that this issue has been fixed. But another reason to have latest firmware.

    Look at firmware, not Magician which is Windows. Its a bootable ISO like a live installer that has to be extracted with tools, but only for firmware update.

    If you can boot, you can see SSD revision & compare to what update is available.

    UEFI/BIOS firmware version:
    sudo lshw | grep -m 1 -A 5 "*-firmware"

    Hey tea for one,

    I've tried to boot with the quick boot disabled, but it still gives me the error message.

    I've runned the ISO, but it says that the latest firmware version is already been installed. Do you have any more suggetions?

    Re: Cannot boot into Ubuntu

    @oldfred I am having an idea, my laptop only boots with the partition scheme MBR. In Rufus there is in the hidden drive properties with a option: add fixes for old BIOSes (extra partition, align). Could this fix the install process or is this only to boot off from a USB?

    You are probably going to have to format the hard drive to use ms-dos(MBR) partitioning for the BIOS to recognize any install. I had a Toshiba laptop that was that way

    Re: Cannot boot into Ubuntu

    I am surprised if a BIOS can see whether drive is MBR or gpt.
    UEFI does read the FAT32 partition flagged as ESP.
    But BIOS just jumps to MBR to start boot process. Gpt has the protective MBR that is identical to BIOS MBR.

    I used gpt with my 2006 laptop when I removed XP and made it Ubuntu only. That was an old BIOS only system.

    Hey Jeremy 31,

    Yes it is now booting into the USB! But what did you do to let your laptop boot into Ubuntu?

    Hmmmm intresting. I wonder why my laptop has missing features. But did you do the install of Ubuntu on your laptop with the partition table?

    Re: Cannot boot into Ubuntu

    That old Toshiba laptop only had 1.5GB of RAM.

    I essentially retired it when 12.04 expired. Battery & coin battery were bad, so only worked with power plugged in and had to reset BIOS clock each time I booted.

    But I tried installing 20.04 Ubuntu desktop and with limited RAM, it would not install. but server version did install & I was able to add a lightweight gui (flashback/fallback).

    I then tried to install Kubuntu as I use that on my desktops and was surprised it installed & ran reasonable well but slow.

    Then new laptop had to go back to Dell, just as I was leaving for trip & wanted a laptop. I had a external SSD with 22.04 Kubuntu in UEFI boot mode. I was able to add a BIOS boot stanza on internal HDD for external SSD drive to directly boot install which made old laptop very functional as long as I did not try to load more than one larger app at a time. With old HDD, I would see a second or two of swap loading if I clicked on another app. With SSD it only hesitated a bit.
