Once you boot into Clover it will already recognize Windows 7, even if you don't install OSX, as soon as you boot Clover you could boot directly in win7 because Clover "scans" your partitions to make our life easier ahah.
Basically in Clover you will have options as: boot Windows from HD, boot Mac OSX from your USB partition (the installation of OSX), Clover options, restart, shutdown....
One thing to keep in mind. When I decided to make my dual boot system I had some unexpected difficulties due to my ignorance in this matter
Basically once you do it, it is not so difficult trust me, but it took days to me because I didn't know the following (mind you, maybe you already know and did right!):
The internal HDD can be formatted in MBR (Master Boot Record) or GPT (GUID Partition Table). It is not related to the partitions, it's referred to the entire disk, so either GPT or MBR, not both at the same time.
Now OSX wants a disk in GPT, for Windows it depends:
-If you install Windows in legacy mode it will use MBR
-If you install Windows in UEFI mode it will use GPT
By default on our Asus N53S (at least on my Asus N53SN) Windows is installed in NON UEFI mode, MBR, the wrong one. To have Windows in UEFI correctly (GPT) I had to boot in the EFI shell manually and start Windows installation the same way you should start Clover as I explained in the post above (insert Windows installation media, go in the EFI shell, look for it with "fsX:", find "bootx64.efi" and boot from it).
So the most natural way would be to have Windows in UEFI mode, so you can install OSX natively in the other partition, both Windows and OSX in GPT mode.
If you have Windows in legacy mode instead (MBR) you can decide to reinstall everything from scratch or to use a patch to convert OSX from GPT to MBR http://www.insanelym...itan-mbr-patch/but unfortunately I reinstalled everything so I'm using GPT and I wouldn't be able to help you in using the patch.
This was the first "great" obstacle that I found while setting up the dual boot.
The second one is always related to the partitioning.
Basically from Windows I shrinked my disk to make space for a second partition for OSX, I rebooted and tried to install OSX in the partition created before, and I received the bad surprise that Disk Utility wasn't able to format the partition in Journaled. Searching the net I found out that it is a known problem and basically the way Windows initialize the HDD is not compatible with OSX which cannot "manipulate" the disk.
The solution that I found was using Gparted Live to format the entire disk and prepare the partitions already formatted in the correct way (NTFS for Windows and Journaled for OSX) as explained in this guide: https://www.reddit.c...indows_10_on_a/
All this could maybe worry you, but trust me finding out later it's worse of course, so maybe it's better to have in mind what the dual boot involves. However after having done it I'm really happy because the two systems are really stable and perfect.
So my advice is to start preparing the disk with Gparted, install Windows in UEFI mode (GPT disk) and finally install OSX. Once you setup everything right with Anerik70's folder (for El Capitan posted in post #19, for Yosemite posted in post #1) you should be good to go in a very short time; so I think that the preparation of the whole dual boot system is probably longer than the single installation of OSX. Of course all this is not needed if you use two different physical disks or if you install OSX on a USB drive...
