#31 I've been able to narrow down my issue to a single hard drive (ATA ST1000DM003-1CH1 (/dev/sdc)). With this hard drive disconnected from the computer, the liveUSB is bootable into the live ubuntu 13.10 64bit OS. An fdisk list states that Disk /dev/sdc doesn't contain a valid partition table. I can recall that this drive was formated through the Disks application, using Partitioning (GPT) under Ubuntu 12.10 32bit. This drive (Seagate) was also a new drive at the time. The hard drive is mountable under a Ubuntu 12.10 32bit install and has shown no issue in reading from and writing to the drive.
Doing (sudo fdisk -l) has shown: Disk /dev/sdc: 1000.2 GB, 1000204886016 bytes 255 heads, 63 sectors/track, 121601 cylinders, total 1953525168 sectors Units = sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 4096 bytes I/O size (minimum/optimal): 4096 bytes / 4096 bytes Disk identifier: 0x00000000 Disk /dev/sdc doesn't contain a valid partition table Disks application info for /dev/sdc: SMART assessment- Disk is OK (31° C / 88° F) Volumes - Drive label / 1.0 TB Ext4 Size - 1.0 TB (1,000,204,886,016 bytes) Device - /dev/sdc Contents - Ext4 (version 1.0) Drive is mounted (Note that the Device doesn't show as /dev/sdc1.) In addition, this recent test was done using a USB flash drive loaded through unetbootin to live boot Ubuntu 13.10 64bit. This boot issue is also seen in the current daily builds of Trusty 32bit & 64bit. Assuming that a drive does not contain a valid partition table as seen by fdisk -l, then the live OS boot attempt will fail. LiveUSB testing of Ubuntu 13.04 32bit has shown no such boot issues with this hard drive connected to the computer. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1241589 Title: ubuntu 13.10 unable to boot on live usb (busy box - initramfs) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/casper/+bug/1241589/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
