    [RESOLVED] Fails to boot

    I've tried two times now, once using dd and the second time using Startup Disk Creator, to burn the ISO to a 32GB PNY thumb drive. Both methods completed without error. But, rebooting the laptop with the inserted USB drive initially shows GRUB in the upper left corner of the screen, followed shortly with a message that is displayed too quickly to fully read, but it says something about architecture (?) then presents the Grub Menu. But selecting the Try option just results in a "-" in the upper left corner and nothing else. I have to power off the laptop, as nothing else does anything.

    I've never had this happen to me before, and never using the dd command to write an ISO to a USB thumb drive. The shasum values match. My laptop is 64-bit as is the ISO.

    Thoughts as too what is happening?

    Can't find grub_platform is the latter part of the message I see flash on the screen before the Grub Menu is presented.

    This is the exact issue: https://askubuntu.com/questions/1288...-grub-platform which at the bottom provides https://bugs.launchpad.net/ubuntu/+s...491/comments/8

    I followed the steps in the second link and when done, rebooted my laptop. The Grub Menu appeared promptly without the preceding GRUB and the subsequent message. It's launching as I type this.

    So am I correct in assuming that newer *buntu ISOs are created specifically as UEFI only now?

      Couple of things I'd try would be to 'zero' the drive with dd (something like sudo dd if=/dev/zero of=/dev/sdX bs=1m​, or similar) then maybe test the stick for problems using badblocks or other tools.

      Otherwise, trying a different USB stick, I can't think of anything, assuming you have booted other ISO images on the same system.

        I'm zeroing the drive now using dd: sudo dd if=/dev/zero of=/dev/sdb bs=4096 status=progress. I'll reburn the ISO using Startup Disk Creator after it's done and reboot. Crossing my fingers.

          IF one uses dd, is it necessary/required to have the target drive formatted first? And if 'yes', as FAT32 or ext4 (for my purposes)?

            I have found that this tool sometimes just doesn't like ISOs for some releases as much as others, at least in the past. But since you have used DD, this obviously rules that out.
            I haven't had a problem using DD and Etcher over the past number if years now. If these didn't work, and the image checked out, it has been a usb stick gone bad, for me.

              What frustrates me more than anything, is that I'm 'experienced; knowledgable' with Linux, and yet, this happens and I'm flummoxed as to why. Think about those who are totally new to Linux; those that don't have a clue beyond powering on their PC, experiencing this! THAT'S what irritates me more than anything else.

                I've now tried two PNY 32GB thumb drives. Failure to boot on both. It is something to do with not being able to find grub.

                  When you reboot the PC with the USB (Kubuntu installer), you interrupt the booting to enter "BIOS," correct? Then you select that USB drive to boot from, right? When you select that USB (from some boot list in your BIOS), are you sure you are selecting that USB that is listed as a UEFI or an EFI device, and not possibly another entry for that USB (that would correspond to the "legacy" entry or the usual MBR entry for that USB)?

                    And double check that you made your BIOS settings to boot from UEFI, not from CSM or some other thing.

                        Oops, so your laptop is 64-bit, and its BIOS is NOT UEFI? Looks like MBR, from your post.

                        I quickly scanned your two links, OMG, lot of work to make that conversion (but I have done it before as a test a long time ago).
                        So you got it now, right?

                        It does appear that the new ISO is made to boot only UEFI, but can we tell that from your two links? (OR, that the new ISO's MBR capability exists but is broken ...)

                          I forgot to mention the following :-

                          GRUB states "Error can't find command grub_platform

                          The USB stick loads perfectly on an UEFI laptop
                          The USB stick loads with "Safe Graphics" on an Intel platform

                          I have used dd if=ubuntu-20.10-desktop-amd64.iso of=dev/sdc with a direct download

                            Yes, the LiveUSB boots to Kubuntu 22.04.1 nicely. As to my laptop, it's over eleven years old, and the BIOS doesn't have support for UEFI.

                            If I had been a Linux newbie, and with my laptop, I would have been miffed (to put it politely) that the created USB wouldn't boot correctly. As an experienced user, I was taken aback that burning the ISO to the thumb drive using dd failed to produce a bootable product! The downloaded ISO file had the correct checksum. That Startup Disk Creator also didn't result in a functional thumb drive was also a shock. Using both methods, I was not informed that the process, once finished, wasn't okay, which clearly it wasn't. I mean, the thumb drive would likely work correctly on a 64-bit PC that did support UEFI, but developers must understand that not everyone is using newer equipment.

                              What you just said in Comment 13 is what was said in that "rejected" Bug report, like in Comment 12 there,
                              https://bugs.launchpad.net/ubuntu/+s...r/+bug/1905491

                              I would agree with you: it is a shock to MBR users who assume all is well!

                                Exactly! MBR isn't dead yet, and likely won't be for a very long time!

                                Yeah, I agree. No reason to kill MBR booting. Somewhere around here, I have whole big how-to on that subject! 👍👌
