Sometimes when you upgrade to Mac OS X 10.5 Leopard, the only obtainable installation alternative might be the Erase and Install. During the installation process, you may come across the following error message:

“You can not install Mac OS X 10.5 on this volume with out changing your installation settings.”

Cause of this issue

This problem could take place due to a variety of reasons. Some common ones among them are as follows:

Ø You have used TechTool Pro to create an eDrive on destination volume

Ø Leopard does complete check of the hard drive prior to list them in destination window. If this check fails, the problem may occur

Due to any of the above reasons, this problem may take place and you may fall in critical problems.
