The current daily Ubuntu Desktop iso file -rw------- 1 sudodus sudodus 2938152960 okt 13 06:25 groovy-desktop- amd64.iso
$ sha256sum groovy-desktop-amd64.iso a1ee702fd38036ac3b22a34657c94a9f1f7cb476bc13b4712ee34dad20499fc2 groovy-desktop-amd64.iso $ md5sum groovy-desktop-amd64.iso 541b509f09d79da944275dc2eaeed137 groovy-desktop-amd64.iso when cloned does *not* boot in my son's HP Elitebook 8560p (It boots in the Lenovo V130). -o- I double-checked that the tweaked iso file, that worked yesterday (according to comment #15) works also today. I cloned it again to the same USB pendrive, that failed with the current daily Ubuntu iso file. And it works in both the HP Elitebook 8560p and the Lenovo V130. The working iso file was tweaked from original=groovy-desktop-amd64_20201010_gpt.iso which was pointing to the daily Ubuntu Desktop iso file dated 2020-10-10. I have saved that file now as a separate file (so that it will not be overwritten at the next zsync). And I have verified that I can create a drive from it via the tweak in comment #15. Please notice that the option -compliance no_emul_toc may cause problems. Anyway, the tweak in comment #21 failed for me. -o- I also tested the tweak in comment #15 on the current Ubuntu Groovy iso file. When cloned the USB drive fails to boot the Lenovo V130, maybe because something is 'set twice'. There is not even any 'Linpus Lite' boot option in the temporary menu. (It boots in the HP Elitebook 8560p.) The output of gdisk is changed from $ sudo gdisk groovy-desktop-amd64.iso GPT fdisk (gdisk) version 1.0.3 Partition table scan: MBR: protective BSD: not present APM: not present GPT: present Found valid GPT with protective MBR; using GPT. to $ sudo gdisk test_mbr.iso GPT fdisk (gdisk) version 1.0.3 Partition table scan: MBR: MBR only BSD: not present APM: not present GPT: present Found valid MBR and GPT. Which do you want to use? 1 - MBR 2 - GPT 3 - Create blank GPT -o- @ Thomas, Would it be useful for you, if I upload the modified iso file that works both in the Lenovo V130 and in the HP Elitebook 8560p? Or can you create such an iso file yourself and do the analysis of its head end? -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1899308 Title: failure to boot groovy daily (again) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu-cdimage/+bug/1899308/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
