Mac OS X 10.7 Lion Developer Previews 1 and 2 currently do not install on older Macs with unsupported Core Duo and Core Solo hardware, but by performing a simple hack you can get these machines to boot Lion.
Apparently the only thing preventing Lion from working on these 32-bit Macs is a single file that is easily removed, located here in a Lion installation:
All you can do is install Mac OS X Lion on a Core 2 Duo machine and move the installation to a Core Duo or Core Solo machine, then delete the PlatformSupport.plist file. This at least works with the first Developer Preview. is the same with hackintosh too.
The problem is I have no other Core 2 Duo PC
so without a C2D,is it possible and how to??????
