Problem solved (at least for me)! This is valid for all PC's!
1. Remove all HDD's physically 2. Configure in BIOS your SATA port(s) "hot-swap-capeable" 3. Boot your PC with the Ubuntu 13.10 Live CD/USB device 4. Ignore error: "no physical device found" 5. If you are on GUI-level re-attach your HDD(s) and install Ubuntu The problem occurs espacially if your previous installation contains a Software-Raid (mdadm) in combination with full encryption (cryptsetup) Good luck! -- 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
