For me, my computer boots fine with no USB devices attached. If I plug in my monitor's USB cable before boot (a Dell U2711, which contains an integrated SD card reader), I receive the "illegal sector size" message. The correct boot device is a SATA SSD disk; it certainly seems like plugging in the SD card reader messes up the device numbering.
I'm using an ASUS P8Z68-V motherboard with a UEFI bios, running an up to date version of Ubuntu Precise. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/975061 Title: grub doesn't find boot To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/grub2/+bug/975061/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
