SUMMARY The latest Neon ISO doesn't boot on my Dell G3 3590 laptop. Other users online mentioned the same issue, all on other Dell laptop models. The same live USB worked fine on an Asus laptop. STEPS TO REPRODUCE 1. Download the latest Neon User ISO (neon-user-20210806-1520.iso) 2. Burn it to an USB using the recommended Rosa image writer 3. Try booting it on a Dell laptop OBSERVED RESULT The live USB didn't boot and I got the following message: Failed to open \EFI\BOOT\? - Invalid Parameter Failed to load image \EFI\BOOT\? - Invalid Parameter start_image() returned Invalid Parameter The screen then went black and then booted into the currently installed OS (Mint 20.2). I tried the same USB on an Asus laptop and it booted perfectly. Live USBs for other distros (Kubuntu 20.04 and 21.04, Mint 20.2 and Solus 4.3) all worked fine. EXPECTED RESULT I expected the live USB to boot normally. SOFTWARE/OS VERSIONS Windows: macOS: Linux/KDE Plasma: neon-user-20210806-1520.iso ADDITIONAL INFORMATION I posted the issue on Reddit and on the KDE forums. A few people replied with the same issue, and they were all also on Dell laptops (Latitude E7470, XPS 9560 and 9590, and another G3 3590). https://www.reddit.com/r/kdeneon/comments/ozcgq6/error_when_booting_into_the_neon_live_usb/ https://forum.kde.org/viewtopic.php?f=309&t=172216
The same problem here with the image "neon-user-20210806-1520.iso", it can't boot in UEFI mode but does in BIOS mode. It show the following Error with a black screen. Invalid image Failed to read header: Unsupported Failed to load header: Unsupported start_image() returned Unsupporte I have installed Kubuntu 21.04 without problems.

I'm testing older ISOs from the Distrowatch archives right now. The image "neon-user-20210715-0945.iso" booted Neon 5.22.3 perfectly. I'll try some more recent images to see when they stop working.
have you talking about this https://distrowatch.com/dwres/torrents/neon-user-20210715-0945.iso.torrent It is a torrent, can't find normal image file.
That's the one! I think it's only available as a torrent, but it checks out. I tried the more recent images from July (neon-user-20210722-0947.iso and neon-user-20210729-0944.iso) and they both worked perfectly too, so it seems to be a very recent problem.
