Optionally, if you have a free partition on any attached drive that's big enough, you can just write the .dmg to the hard drive partition rather than burning a DVD. This is common practice for many Apple engineers. Then you can boot from that partition rather than booting from the DVD. It's typically much faster than burning a DVD, too. Well then you can just leave the dmg as a dmg and just mount it with hdid (etc) as well too. That is you don't have to expand the dmg's onto disk. I don't think you can boot from it in that case, though. And you need to boot from it to run the installer. No burning should be necessary. Any particular Mac OS X version can be installed onto another partition by mounting the .dmg, logging into the root account and double-clicking on the image's / System/Installation/Packages/OSInstall.mpkg. You're only required to boot from a CD/DVD when installing onto your [solitary] boot volume. No burning is necessary, but the best way to do this in the absence of burning or a DL DVD writer is to restore the .dmg to any partition or drive large enough to hold it, boot from that, and perform the installation on the desired volume, as was originally suggested. As Peter noted, while installing directly from the packages may work in the general case, if there is a newer version of the installer that is intended to be used, there may be issues if you're not using the appropriate installer version.
