trying to create a bootable flash utility drive

Discussion in 'Misc' started by Amanda Ripanykhazova, Dec 12, 2011.

  1. Am having a problem doing something I have done before

    Trying to create a bootable utility disc from a CD/DVD. In the past I
    am sure I have just created a disc image out of the CD and restored it
    onto the USB drive. I have it in front of me! It works

    I just bought an updated utility disc which is of course bootable. But
    when i follow this procedure again, the resulting disc isnt exactly
    the same size as the DVD and isnt bootable??

    So I went into the DVD again on Disc Utility and suddenly saw that
    whereas the whole thing is still only about 128 MB, there are in fact
    three 'parts' to it, - one PowerPC startup one, one with the software
    on it which I want to use which is called Intel startup and a 'the
    rest' partition which has the same name as the others.

    I thought I would be a wiseguy and try to do just the Intel bit of it
    but Disk Utility then gives me the error message that the USB drive
    isn't big enough? If the whole DVD is only 128 mb as is the
    resultant .dmg file, how can a bit of it (and I think it is probably
    only the bit which makes it bootable) be too big? I have of course
    formatted it journaled HFS although I think that when DU creates the
    image it does format it again as part of the 'erase disc" bit of the
    process.

    Can someone tell me what is the obvious thing I did last time which i
    cant remember now please! I called Apple and after consulting with
    various supervisors, they told me that it can of course be done but
    they aren't allowed to tell users this sort of thing.

    I'm not sure exactly what problem you're facing, but:

    If you want to create a bootable copy of a Mac OS X boot disc of any
    sort, the only procedure I know of which works is to use a utility such
    as SuperDuper! or Carbon Copy Cloner.

    SuperDuper!

    The best instructions on making a boot disk on a usb stick are in:

    http://gizmodo.com/5389166/how-to-hackintosh-a-dell-mini-10v-into-the-ul
    timate-snow-leopard-netbook

    You have to format the usb stick, make it one partition using the GUID
    partition table.

    Also, the dvd can't ony have 128 MB on it, otherwise it would be on a
    CD. What size is your usb stick? I'd try one at least 8GB, many install
    disks are between 8-9GB these days.

    According to an article in the October issue of the UK MacFormat magazine
    (for making a bootable Lion install drive):

    "First find a USB (or if you prefer, FireWire) drive of
    at least 5GB in size. You can use an external hard
    disk drive or a flash drive; it doesn't matter which,
    as long as it's formatted to Mac OS Extended (Journaled).
    If it isn't, reformat it using Disk Utility."

    What's the procedure? I can't see anything in Disk Utility Help about
    this issue - the nearest hint is:

    For technical information about creating a restore disk image, see the
    Apple Software Restore (ASR) manual (man) page.

    There is no ASR man page available here - it's asr (as the link at the
    bottom of the page correctly states).

    But: I've had a look, and this is all it says on the subject of making a
    copy of a disc bootable:

    --updatebless

    When performing a non-erase restore,
    --updatebless will update the appropriate
    information required for the restored volume
    to boot if the source image is bootable
    (equivalent to sudo bless --mount <volume> --setBoot).

    I'm not sure how to apply this information to the use of Disk Utility.

    Rowland.

    That was exactly how this information applies to DU.

    Snot that my memory is failing, it is just that I am reasonably sure i
    remember simply making a disc image of the CD and then restoring it
    under simple "restore" and the CD which was startable became a flash
    memory drive which is startable!

    Now it suddenly doesnt work to create a startable disc (whatever
    parameters I use, however I format it or dont etc)

    Yes I've done that with Leopard that came with my iMac 3.06GHz but
    nothing more recent.
