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.

  • I forgot to add that further on I will test it by simulation in virtual machine on VirtualBox. Will it resemble the real situation? Of course the disk capacities will be smaller. – Kamil Kuczaj May 22 '15 at 11:13

    You can install Windows to a logical paritions it just can't be the system partition.since it cannot be activated. There are tons of instructions on how to get multi-boot systems up and running. Here is a small explination of the process if you place a logical partition into the mix. I won't be submitting an answer since there are tons of questions on multi-booting already, and the tutorial I linked to, is something like 9 pages long. – Ramhound May 22 '15 at 11:21
  • Thank you, @Ramhound. I just wanted an expert to have a look at my problem and a little tip since I've never multi-booted (only double-boot). I just don't want to screw up anything, because my final exams are getting closer and closer. – Kamil Kuczaj May 22 '15 at 11:23

    This isn't something you do before final exams. You need to perform a backup. Even if you know what your doing you can still choose the wrong option. Wait until you can afford to make a mistake before you do this. – Ramhound May 22 '15 at 11:24
  • OK. Maybe you're right. I just fine computers much more interesting than maths and theories. Thanks again. – Kamil Kuczaj May 22 '15 at 11:26
