While trying to Install Sharepoint 2010 on Windows 7 to setup Enterprise Portal, I was getting an error that Windows Server 2008 R2 is needed. I was able to install after adding following setting to the file in the setup directory.
File:
.../SharepointSetup/Files/Setup/Config.xml
Open the above mentioned file and add the following line to it.
<Setting Id="AllowWindowsClientInstall" Value="True"/>
After adding this line, the file would like something like that.
<Configuration>
<Package Id="sts">
<Setting Id="SETUPTYPE" Value="CLEAN_INSTALL"/>
</Package>
<DATADIR Value="%CommonProgramFiles%\Microsoft Shared\Web Server Extensions\14\Data"/>
<Logging Type="verbose" Path="%temp%" Template="Microsoft SharePoint Foundation 2010 Setup *.log"/>
<Setting Id="UsingUIInstallMode" Value="1"/>
<Setting Id="SETUP_REBOOT" Value="Never" />
<Setting Id="AllowWindowsClientInstall" Value="True"/>
</Configuration>
Once you add this line, run the setup again and you should be good to go.
