Thanks Phillips for answering. Could you help me to understand what the installer is writing to the mbr? Is grub itself or just something that tell to the bios in which partition it can find grub?
In the past I used to create a /boot partition, what did it contain? Grub? All these question because today I have tried to boot the USB on another machine with BIOS UEFI in legacy mode and it was able to read it properly. I have formatted the key and generated the table partition several time in msdos under gpated or directly from the installer but it always starts from sector 32. Reading around this should not happen with those new tools, isn't it? How can I force the first sector position? what about using gtp? I do not now if "old" bios (~2yrs old machine) can read it. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1245147 Title: Ubuntu 13.10 does not boot from USB stick 3.0 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/grub2/+bug/1245147/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
