I've got a question. Is it possible to triple boot on a Sony Vaio laptop (VPCF22L1E). I've installed Windows 8.1 Pro after upgrading from Windows 7. Then I installed elementaryOS due to my programming classes and due to that it's cool and really fast. My partition map looks like this:
I want to install customized Windows 7 DreamOS (it's modified to increase performance and I think it's the fastest OS I ever come across). It has a special gaming mode, too. The laptop seemed to work flawlessly with Windows 7. SONY officialy stated that the model I've got should not be upgraded to Windows 8 even however they do offer drivers for each module ;).
So my question is: Is it possible to install that Windows 7 system on a 63,86GB free space on a logical partition? I do not wish to reinstall all systems, which the other guys advised to do in chronological order: Windows 7 first, Windows 8 second, and elementaryOS the third. Thanks in advance.
