 </modules>
 <frontend>

Change your etc/config.xml to this-

<?xml version="1.0"?>
<config>
 <modules>
 <Dinesh_Hello>
 <version>0.1.0</version>
 </Dinesh_Hello>
 </modules>
 <frontend>
 <routers>
 <hello>
 <use>standard</use>
 <args>
 <module>Dinesh_Hello</module>
 <frontName>hello</frontName>
 </args>
 </hello>
 </routers>
 <layout>
 <updates>
 <hello>
 <file>hello.xml</file>
 </hello>
 </updates>
 </layout>
 </frontend>
 <global>
 <blocks>
 <hello>
 <class>Dinesh_Hello_Block</class>
 </hello>
 </blocks>
 </global>
</config>
