    Default Trouble getting external install to load

    I'm trying to get my external HDD to boot BT3, thanks to PureH@te for a very thorough explaination and walk-through, got everything done, no problems, until i go to boot and get "No Operating System Found." According to the BIOS it should be able to boot USB, but nothing, not even an Error.

    Here's what im working with:

    BT3 installed on a 14Gb external with 3 partions

    Computer is:
    Toshiba Satellite A105-S4201
    Bios was updated in Feb. to the newest release.

    Thanks

    You have to give us some more detail if u want us to help.
    Please post your lilo.conf / grub.conf (depending on what bootloader you use)
    And make sure you set the bootable flag on your disk/partition.
    Be sensitive in choosing where you ask your question. You are likely to be ignored, or written off as a loser, if you:

    * post a very elementary question to a forum where advanced technical questions are expected, or vice-versa
    * cross-post to too many different newsgroups

    Default

    lilo.conf

    lba32
    boot /dev/sda1
    prompt
    timeout=60
    change-rules
    reset
    vga=791
    image = /boot/vmlinuz
    root = /dev/sda3
    label = Backtrack 3

    this is in the first partition, in this case sda1

    and when i go into cfdisk the sda1 is flagged as boot

    here is the output of cfdisk:
    cfdisk 2.12r

    Disk Drive: /dev/sdc
    Size: 15002910720 bytes, 15.0 GB
    Heads: 64 Sectors per Track: 32 Cylinders: 14307

    Name Flags Part Type FS Type [Label] Size (MB)
    ------------------------------------------------------------------------------
    sdc1 Boot Primary Linux ext3 53.48
    sdc2 Primary Linux swap 2000.69
    sdc3 Primary Linux ext3 12947.82



    i think its listing it as sdc now because it has two other harddrives mounted right now also??? the one internal and an other external?

    what else would you like?

    According to the BIOS it should be able to boot USB
    Are you sure you set USB to the default Boot Option in your BIOS?

    In case you did, without avoiding to guess arround , try that:

    lba32
    boot /dev/sdc1
    prompt
    timeout=60
    change-rules
    reset
    vga=791
    image = /boot/vmlinuz
    root = /dev/sdc3
    label = Backtrack 3
