the type of testing done in installation testing is static 
testing.i.e.we will just verify the documents and check 
whether we are able to install the product according to the 
guide lines given.so here we will be doing only 
verification.

the type of testing done in system testing is dynamic 
testing.here we will execute test cases.

correct me if i am wrong.

system test carried out after integration of all the system 
components or modules. During system testing tester has to 
look for broken functions by doing Functionality testing. 
And System test includes Performance Testing to evaluate 
system performance and Memory testing for memory leaks and 
also it includes Soak test which exhibits the defects 
during system long runs.

system testing and sanity testing.
