@leok, When cloning works (in all computers and boot modes), we can consider this bug as squashed.
When Rufus fails in its default mode, we can select 'dd-mode' which means cloning, and the result should be identical to that of the Ubuntu Startup Disk Creator and other cloning tools (Disks, mkusb (when cloning), Win32DiskImager, Balena Etcher ...). It seems like the Lenovo V130 is a corner case, that is left behind. Cloned USB drives are still failing in that computer. But it seems that all other computers tested by us are happy to boot from cloned Groovy iso files. ** Attachment added: "rufus-dd-mode.png" https://bugs.launchpad.net/ubuntu-cdimage/+bug/1886148/+attachment/5394068/+files/rufus-dd-mode.png -- 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
