    Hey all, I'm trying to install ubuntu from a thumb drive. Basically, I'm converting the .iso to an .img, and restore the thumb drive from the .img, trying to make it bootable. I'm following the procedure form the ubuntu website...:

    TIP: Drag and Drop a file from Finder to Terminal to 'paste' the full path without typing and risking type errors.

    Download the desired file
    Open the Terminal (in /Applications/Utilities/ or query Terminal in Spotlight)
    Convert the .iso file to .img using the convert option of hdiutil (e.g., hdiutil convert -format UDRW -o ~/path/to/target.img ~/path/to/ubuntu.iso)
    Note: OS X tends to put the .dmg ending on the output file automatically.
    Run diskutil list to get the current list of devices
    Insert your flash media
    Run diskutil list again and determine the device node assigned to your flash media (e.g. /dev/disk2)
    Run diskutil unmountDisk /dev/diskN (replace N with the disk number from the last command; in the previous example, N would be 2)
    Execute sudo dd if=/path/to/downloaded.img of=/dev/rdiskN bs=1m (replace /path/to/downloaded.img with the path where the image file is located; for example, ./ubuntu.img or ./ubuntu.dmg).
    Using /dev/rdisk instead of /dev/disk may be faster.
    If you see the error dd: Invalid number '1m', you are using GNU dd. Use the same command but replace bs=1m with bs=1M.
    If you see the error dd: /dev/diskN: Resource busy, make sure the disk is not in use. Start the 'Disk' and unmount (don't eject) the drive.
    Run diskutil eject/dev/diskN and remove your flash media when the command completes
    Restart your Mac and press alt while the Mac is restarting to choose the USB-Stick

    everything goes through fine, except, when I restart my mac to see the boot options... all I see is Macintosh HD

    Any suggestions?

    Thanks in advance.

    Those instructions didn't work for me either, but I've tried it with Ubuntu 10.10. Eventually, I burned a DVD (didn't have a blank CD) and installed it from there. Worked like a charm. Ubuntu really has come a long way and I like it almost as much as Mac OS X - if only they added QuickLook. :)

    Up the irons
    #3 I haven't tried it, though. If I'm not mistaken I think KDE has something similar...
