    Exclamation Installing on freecom external 400GB.

    Hey all,

    I recently tried to install ubuntu on my external USB freecom 400GB HD.
    What I did was boot live CD double click the desktop installer so I could chat on msn at the same time , I mounted the XHD and selected auto partition just one question where do I put the grub loader on the XHD drive or it says Hd0 or something else.....

    Becuase when I load it the biod does not detect the hard drive....
    It will not load up I have been into bios and it has not detected it.
    Its also screwed up my windows XP drive as it cannot boot windows either!

    Any help on this one is much thanked.

    Re: Installing on freecom external 400GB.

    The best method for an external USB drive is to let the installation install the GRUB bootloader to the USB drive, you can see which drive the USB device is typing on a command line:
    Code:
    sudo fdisk -l
    (It should be something like "sdc")

    You should have a setting within your BIOS to allow boot from USB. With this option, when you have the USB drive connected, your BIOS will boot from the external drive (if your boot order is 'USB - CDROM - HARD DRIVE'). You can re install GRUB but you'll need to repair your MBR on your Window's drive.

    Does this make sense to you?

    Ok this is what I got.

    Code:
    ubuntu@ubuntu:~$ sudo fdisk -l
    
    Disk /dev/sda: 300.0 GB, 300069052416 bytes
    255 heads, 63 sectors/track, 36481 cylinders

    Disk identifier: 0xcab10bee
    
       Device Boot      Start         End      Blocks   Id  System
    /dev/sda1   *           1       35767   287298396    7  HPFS/NTFS

    ubuntu@ubuntu:~$
    Looks to me like linux and windows are perfectly installed I guess its to do with boot loading etc... Im confused. It will not load windows.

    Looks good. First thing you need to do is unplug the USB drive, boot from the Window's install disc and select recovery mode. Select to repair MBR for your Window's installation (fixmbr).

    Once you can boot into Window's successfully without the USB drive installed, insert the Ubuntu Live CD and reboot. Plug the USB drive in (this should auto mount). Open a terminal (Accessories > Terminal) and type:
    Code:
    sudo grub
    This will give a "grub" prompt:
    Code:
     grub>
    type:
     grub> find /boot/grub/stage1
    find /boot/grub/stage1
     (hd0,0)
    grub>
    This shows stage1 on my install within the primary drive first partition (hd0,0). Yours will probalbly show (hd5,0) or something along those lines. Use the output for the following:
    Code:
     grub> grub-install /dev/hd5 (whatever was returned from above)
    You should now have the GRUB bootloader insalled on the USB drive away from the Window's install. If you have your boot order correct (USB - CDROM - HARD DRIVE) you should be able to boot with your USB drive connected and it will boot Ubuntu. With it unplugged it will boot Window's.

    Good Luck, let me know how it turns out........

    Update::.
    Examples of the difference from the GNU/Linux and GRUB device names:

    1st Physical Hard Drive:
    Linux IDE: GRUB IDE: Linux SCSI: GRUB SCSI:
    /dev/hda1 ----(hd0,0)----- /dev/sda1-------(hd0,0)
    /dev/hda2 ----(hd0,1)----- /dev/sda2-------(hd0,1)
    /dev/hda3 ----(hd0,2)----- /dev/sda1-------(hd0,2)
    /dev/hda4 ----(hd0,3)------/dev/sda2-------(hd0,3)

    2nd Physical Hard Drive:
    Linux IDE: GRUB IDE: Linux SCSI: GRUB SCSI:
    /dev/hdb1---- (hd1,0)----- /dev/sdb1------ (hd1,0)
    /dev/hdb2---- (hd1,1)----- /dev/sdb2------ (hd1,1)
    /dev/hdb3---- (hd1,2)----- /dev/sdb1------ (hd1,2)
    /dev/hdb4---- (hd1,3)----- /dev/sdb2-------(hd1,3)
