A better (and faster) way to make bootable Lion Disk

levo said:

If you just restore the dmg to a flash drive, during installation of Lion, it creates a restore partition on your drive, reboots your mac, and installs from that partition. Thanks to hackint0shers, you can create a "classic" boot disk that just installs from your flash drive. Credit goes to original creator of the script, I've just made small edits..

download the script:
http://www.mediafire.com/?02i0a5tt0uu4o3q

you can check the bash script with textedit (to be safe)

- plug your flash drive, format/partition it with disk utility (guid/mac os extended)
- open terminal, type sudo
- drag the script to the terminal
- drag the Install Mac OS X Lion.app file to the terminal
- and drag your flash drive to the terminal

you will end up with something like
sudo /download/mkboot /download/Install\ Mac\ OS\ X\ Lion.app /Volumes/Flash

The script will mount the installer .dmg, restore it to the flash disk, copy packages to the disk, copy kernel to the disk and eject image&disk

Than you can plug the flash disk, power on your mac and hold alt key to select the flash disk and install Lion..

here is the mkboot, just in case...

Code:

#!/bin/bash -e

function usage() {
  echo "Usage: `basename $0` <Lion install app> <Target volume>" 1>&2
}

if [ $# -ne 2 ]; then
  usage
  exit 1
fi

LION_INSTALL_APP=$1
TARGET_VOLUME=$2
BASE_TARGET='/Volumes/Mac OS X Base System'
IN_APP_DMG='Contents/SharedSupport/InstallESD.dmg'
SCRIPT_DIR=`dirname $0`

if [ ! -d "$LION_INSTALL_APP" ]; then
  echo "$LION_INSTALL_APP: No such file" 1>&2
  usage
  exit 2
fi

if [ ! -d "$TARGET_VOLUME" ]; then
  echo "$TARGET_VOLUME: No such directory" 1>&2
  usage
  exit 3
fi

if [ $EUID -ne 0 ]; then
   echo "This script must be run as root" 1>&2
   exit 4
fi

function echob() {
  echo "`tput bold`$1`tput sgr0`"
}

echob "Attaching OS X Lion..."
hdiutil attach -mountpoint $SCRIPT_DIR/lioninst "$LION_INSTALL_APP/$IN_APP_DMG"

pushd `dirname $0` > /dev/null

echob "Restoring BaseSystem.dmg to $TARGET_VOLUME..."
asr --source lioninst/BaseSystem.dmg --target "$TARGET_VOLUME" --erase --noprompt

echob "Adopting on-disk ownership on $BASE_TARGET..."
vsdbutil -a "$BASE_TARGET"

echob "Copying Packages from OS X Lion main image..."
rm "$BASE_TARGET/System/Installation/Packages"
rsync -r --progress lioninst/Packages "$BASE_TARGET/System/Installation/"

echob "Copying mach_kernel from OS X Lion main image..."
cp -r lioninst/mach_kernel "$BASE_TARGET"

echob "Detaching OS X Lion main image..."
hdiutil detach lioninst

echob "Ejecting $BASE_TARGET..."
diskutil eject "$BASE_TARGET"

echob "All done."
