-- reply to @Thomas #112 (start paste) So if we want to propose a workaround for the current layout, it would be a good base if you could confirm that j3400 boots after the plain procedure with no other experiments inbetween:
# Patch the ISO already as image on hard disk ISO=ubuntu-22.04-desktop-amd64.iso dd if=/dev/zero bs=1 count=16 of="$ISO" conv=notrunc seek=462 # Put it onto the USB stick as you usually do. E.g. sudo dd bs=4M oflag=sync status=progress of=/dev/sdb if="$ISO" Then you would check if it boots twice on the j3400. If the second boot succeeds and shows a writable big partition as last one, then we could be sure that this procedure is a valid workaround. A run of sudo xorriso -indev stdio:/dev/sdb -report_system_area plain would (hopefully) confirm that there is no second MBR partition with boot flag. Of course it would be enough if you can confirm that you did this already during the experiments, with no intermediate manipulations. But given the curvy way of this bug report, we need to be sure. -- (end paste) I grabbed my thumb-drive 2; Ubuntu-MATE jammy (2022-04-19) - plugged into j3400; enter pressed [just] @12:28 using room clock, plymouth seen at 12:36, maybe-ubiquity appeared at 12:38 This wasn't required/requested; but I omitted `sudo` for last; so added here --- (start paste) guiverc@d960-ubu2:~/uwn/issues/735$ sudo xorriso -indev stdio:/dev/sdb -report_system_area plain [sudo] password for guiverc: xorriso 1.5.4 : RockRidge filesystem manipulator, libburnia project. xorriso : NOTE : Loading ISO image tree from LBA 0 xorriso : UPDATE : 774 nodes read in 1 seconds libisofs: NOTE : Found hidden El-Torito image for EFI. libisofs: NOTE : EFI image start and size: 1422522 * 2048 , 8496 * 512 xorriso : NOTE : Detected El-Torito boot information which currently is set to be discarded Drive current: -indev 'stdio:/dev/sdb' Media current: stdio file, overwriteable Media status : is written , is appendable Boot record : El Torito , MBR protective-msdos-label grub2-mbr cyl-align-off GPT Media summary: 1 session, 1424812 data blocks, 2783m data, 4849m free Volume id : 'Ubuntu-MATE 22.04 LTS amd64' System area options: 0x00004201 System area summary: MBR protective-msdos-label grub2-mbr cyl-align-off GPT ISO image size/512 : 5699248 Partition offset : 16 MBR heads per cyl : 0 MBR secs per head : 0 MBR partition table: N Status Type Start Blocks MBR partition : 1 0x00 0xee 1 15630335 MBR partition : 2 0x80 0x00 0 1 GPT : N Info GPT disk GUID : 92da1293cf19e54b80558e26d983bc85 GPT entry array : 2 248 separated GPT lba range : 64 15630272 15630335 GPT partition name : 1 490053004f003900360036003000 GPT partname local : 1 ISO9660 GPT partition GUID : 1 92da1293cf19e54b80548e26d983bc85 GPT type GUID : 1 a2a0d0ebe5b9334487c068b6b72699c7 GPT partition flags: 1 0x1000000000000001 GPT start and size : 1 64 5690024 GPT partition name : 2 41007000700065006e006400650064003200 GPT partname local : 2 Appended2 GPT partition GUID : 2 92da1293cf19e54b80578e26d983bc85 GPT type GUID : 2 28732ac11ff8d211ba4b00a0c93ec93b GPT partition flags: 2 0x0000000000000000 GPT start and size : 2 5690088 8496 GPT partition name : 3 4700610070003100 GPT partname local : 3 Gap1 GPT partition GUID : 3 92da1293cf19e54b80568e26d983bc85 GPT type GUID : 3 a2a0d0ebe5b9334487c068b6b72699c7 GPT partition flags: 3 0x1000000000000001 GPT start and size : 3 5698584 600 GPT partition name : 4 GPT partition GUID : 4 a77519baa6474c698e9d5848797c7dc5 GPT type GUID : 4 af3dc60f838472478e793d69d8477de4 GPT partition flags: 4 0x0000000000000000 GPT start and size : 4 5701632 9928641 guiverc@d960-ubu2:~/uwn/issues/735$ --- (end paste) guiverc@d960-ubu2:/de2900/ubuntu_mate_64$ cp -pv jammy-desktop-amd64.iso jammy-desktop-amd64.iso.scdbackup 'jammy-desktop-amd64.iso' -> 'jammy-desktop-amd64.iso.scdbackup' guiverc@d960-ubu2:/de2900/ubuntu_mate_64$ dd if=/dev/zero bs=1 count=16 of=jammy-desktop-amd64.iso.scdbackup conv=notrunc seek=462 16+0 records in 16+0 records out 16 bytes copied, 0.205961 s, 0.1 kB/s guiverc@d960-ubu2:/de2900/ubuntu_mate_64$ sudo dd bs=4M oflag=sync status=progress of=/dev/sdb if=jammy-desktop-amd64.iso.scdbackup [sudo] password for guiverc: 2918014976 bytes (2.9 GB, 2.7 GiB) copied, 786 s, 3.7 MB/s 695+1 records in 695+1 records out 2918014976 bytes (2.9 GB, 2.7 GiB) copied, 785.505 s, 3.7 MB/s Ejected thumb-drive (2) & booted on plugged into hp.dc7700; it failed to boot :( On j3400; pressed ENTER (at grub) at 13:10 (room clock)..
