I had a similar issue with a 13.10 live DVD. It was fine until I had a new SATA 2TB drive, then I could not run or install from the DVD, I just got busybox and initramfs error and the PC was locked.
I read that this might be a SATA bios issue and the tip was to change the SATA mode or choose RAID option, I have no SATA mode menu in mi BIOS (Dell E521) for SATA so I chose the RAID option. It made no difference for me, but then I tried disconnecting both my HDD SATA drives and voila! it worked fine. Once installed I could plug the other HDD's back in and its still works fine. -- 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/+bug/1241589/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
