Hi, I installed MakuluLinux with Windows 10 insider preview and things were working fine until having EasyBCD on both Windows 10 insider preview and Windows 7 Pro went do-lally. What you will discover is that you are limited with what you can do as Windows 10 (unlike 7 or 8) creates THREE primary partitions - A system partition like 8 of 350 Mb, then Windows System partition (C:\) then a 'Rescue' partition after 'C:\'. You have to do the cursory chkdsk and defrag before making changes, right click 'computer' and select 'manage' then go to 'disk management'. Select 'C:\' right-click and select 'shrink volume' and let Windows 10 do its thing regarding this. Next run chkdsk and defrag after completion. Now between the end of the shrunk 'C:\' and the 'Rescue' partition, you have to create ONE extended partition and inside of that:
1. 512 Mb /boot partition formatted to Ext4
2. 30 Gb Primary partition marked as '/' and formatted to Ext4
3. a. now at END of what is left create your 'swap area' (4 Gb - it self formats to create file system)
b. between '/' and 'swap area' create your '/home' partition.
Be warned, Windows 10 is unpredictable and the fact they know what you are doing remotely 'could' end up with you saying goodbye to Zorin - that said I did not have a 'standard' set up with 3 drives in the box and my main drive in the 'hot bay' of my CoolerMaster Silencio 650 Tower!
