You will need:
- preboot/bootable os x install media
- a patched osinstall.mpkg somewhere accessible
Once past language selection, launch Disk Utility from the Utilities menu and format and name (I'll call it TestDrive) your partition, close Disk Utility.
open terminal (it may be a good idea to open a new tab so you have one spare), and copy the installation files to your new partition with:
CODE
cp -R /Volumes/Mac\ OS\ X\ Install\ DVD/System/Installation/Packages /Volumes/TestDrive
then copy the patched osinstall.mpkg to the Packages folder with:
CODE
cp -R /Volumes/SomeWhere/OSInstall.mpkg /Volumes/TestDrive/Packages
then start a new installer with:
CODE
/System/Library/CoreServices/Installer.app/Contents/MacOS/Installer
And browse to /Volumes/TestDrive/Packages/OSInstall.mpkg
alternatively:
CODE
/System/Library/CoreServices/Installer.app/Contents/MacOS/Installer /Volumes/TestDrive/Packages/OSInstall.mpkg
does it all in one.
The install should run as usual.
