10.7: How to get a full Lion install disc for a new MacBook Air or Pro
Authored by: wallybear on Sep 07, '11 04:07:32PM
Instead of force-quitting you can go to Terminal and type:

ln /"Mac OS X Install Data"/InstallESD.dmg   /Users/yourusername/Desktop/LionInstall.dmg

where yourusername is the name of your account (and home folder); this will create an hard link to that file called LionInstall.dmg placing it on your desktop. At that point you can make Installer reboot your system: it will delete the InstallESD.dmg file, but thanks to the hard link it will remain intact on your desktop.

Explanation: an hard link is undistinguishable from the real file. A file is removed from a volume only when all its hard links are removed; that's why the file will "survive" also if Installer deletes it.

Another way is to simply copy somewhere the InstallESD.dmg file before rebooting, but the hard link solution is more elegant as it does not duplicate the file.

While that's true, if you don't force-quit, it will reboot your system and install Lion on the disk you selected, tying your machine up for a half-hour. If all you wanted to do is get the installer, force-quitting is more efficient.
