I attach a photo of the temporary boot menu to this comment too, so that you need not skip between the bug reports.
I am almost 100% sure that no user has tampered with the boot settings until yesterday, when I turned off first secure boot, then UEFI. The boot menu option "Linpus Lite (<name of the USB drive>)" was there, when the computer arrived from the vendor (with Windows 10 pre-installed), and it works in UEFI mode with previous versions of Ubuntu, for example Ubuntu 20.04.1 LTS and daily Groovy iso files until June (this bug was detected in the beginning of July). I switched a RAID setting of the NVMe drive to AHCI in order to be able to install Ubuntu. This is the only modification that I know of in the whole UEFI/BIOS system, and it should not affect the action of "Linpus Lite" for booting from USB. ** Attachment added: "lenovo-v130_boot-option-menu.jpg" https://bugs.launchpad.net/ubuntu-cdimage/+bug/1886148/+attachment/5407575/+files/lenovo-v130_boot-option-menu.jpg -- 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 [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
