Preseed-based workarounds are insufficient when installing from a USB device onto a bare (unpartitioned) drive, as it's not possible for the preseed to actually load (the installer gets stuck "loading the CD-ROM" since the proper device has already been mounted on /media).
mountmedia runs prior to to the preseed and picks the first suitable device. With a bare drive (attached as /dev/sda), it's the USB drive (/dev/sdb1). -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1347726 Title: ubuntu14.04 installation hang on "The installer has detected that the following disks have mounted partitions" To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/debian-installer/+bug/1347726/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
