Install Snow Leopard in a Lion partition

I will answer my own question. Yes, you can create a partition on Lion to be used for Snow Leopard, and your original install disc that came with the computer is used to install it into that partition. And the last question before beginning the install asks where you want to install it.

It is quite easy. In your Lion applications, go to "Utilities" then to "Disk Utilities". In the upper left hand corner click on the topmost disk, and the menu bar on the right will have "Partition" as an option. Click that, and it will show you your current disk partition. Click on the "+" in the lower left corner to add a partition. You can name it what you like. Snow Leopard requires about 6 GB, so set the partition size at at least 10GB. I am told this is enough if your are only running several programs, but if you have adequate disk space you can make it a little larger. Once you have done this, you can close everything out.

You can now shut down your computer, and insert the original installation disk that came with the computer. When you start up, it will boot from that, and will install the Snow Leopard. The last question it will ask before installing is what disk/partition do you want to install it on, and you can choose the partition you have just created. This should do it for you. Let me know if it works successfully.

No, as far as I can tell, you have to run each OS separately. You go to "System Preferences" and under "startup disc" you can choose which OS you want to run.

No. OS X Snow Leopard runs in a Mac environment, and VMWare and Parallels are PC environments. However, I don't understand why you would want to, as you can create a partition in OS X Lion and install Snow Leopard in that as discussed above.

I completely agree on this, but this was the only solution where I didn't have to pay Intuit again for a version of QuickBooks that I had recently bought. I would note that Parallels runs just fine in Lion, and my current version of Quicken runs the same as before in it.

I haven't tried it yet in Lion, but the latest Parallels runs just fine in Lion, and I have been running Quicken in Parallels for several years with no problems. I don't think there should be any problems. Intuit makes a version of Quicken to run on a PC, hence it runs in Parallels. There is also a version that runs on the Mac, but I have not checked to see if the current version runs in Lion or not. I have had to run it in Parallels, as my bank does not support the Mac version.

No problem. I have described how to do this in my July 25 note above. And my July 31 note describes how to switch between Snow Leopard and Lion. You can install programs in either OS just the way you normally would. I have found that Snow Leopard takes more space than expected, so I would make the partition at least 20GB.
