@ Steve Langasek (vorlon), According to your request I continue the dialogue here about problems to boot a Lenovo V130 in UEFI mode with the current daily Groovy iso files.
This problem was reported in comment #31 https://bugs.launchpad.net/ubuntu-cdimage/+bug/1886148/comments/31 - When I select the USB drive from the temporary menu, it skips to the internal drive. This is a different failure mode compared to the previous iso files. (This computer is willing to boot from the grub-n-iso system of comment #26 and from cloned drives made from groovy iso files from June.) https://dustinweb.azureedge.net/media/494085/v130.pdf --- Previously I have not touched the UEFI/BIOS system of the *Lenovo V130* that I have access to, but now, that you ask about it, I had better do it in order to help identify what goes wrong, when trying to boot USB drives cloned from Groovy ISO files. When testing Groovy iso files, the fix against the boothole bug was entered into this computer, so that USB drives that used to boot would no longer boot. I turned off secure boot, and then it was possible again to boot for example Ubuntu 20.04.1 LTS (cloned to a USB drive). This matches the observation, that Groovy iso files worked until you modified the boot system (when you removed syslinux boot in BIOS mode, but obviously also modified the boot system in UEFI mode). But USB drives cloned from the current Ubuntu Groovy as well as Lubuntu Groovy do not boot. This is when using the boot option in the temporary boot menu (F12) "Linpus Lite (<name of the USB drive>)" in the picture attached to the previous comment. This is the only available USB boot option in UEFI mode. Then I turned off UEFI mode and set teh computer to boot in 'legacy mode'. Now there were more boot options in the temporary boot menu (F12). These options are shown in the picture attached to the previous comment. The option "USB Hdd: <name of the USB drive>" *works* also with USB drives cloned from the current Ubuntu Groovy as well as Lubuntu Groovy. So the problem in this case is not due to secure boot, but the "Linpus Lite" boot option does not work with the current Groovy iso files. It works with older iso files including Ubuntu 20.04.1 LTS and Groovy iso files from before you modified the boot system (when you removed syslinux boot in BIOS mode, but obviously also modified the boot system in UEFI mode). I attach the output of`efibootmgr -v`. ** Attachment added: "efibootmgr-of-lenovo-v130.txt" https://bugs.launchpad.net/ubuntu-cdimage/+bug/1886148/+attachment/5407572/+files/efibootmgr-of-lenovo-v130.txt -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1886148 Title: failure to boot groovy daily To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu-cdimage/+bug/1886148/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
