I did the exact same thing recently on my latest build https://www.tonymacx86.com/threads/asus-ux430-laptop-crossing-dark-side-or-not.243618/. On previous builds I always used separate SSD's but this was a laptop with only one hard drive so really, I did not have much of a choice to have dual boot using one drive. So far it works fine, I have final cut pro, etc.. on the OSX partition, and Windows 10 is still there too.

There are lots of guides on this forum, you just have to search for them. You can run the OSX installer and adjust your partition during OSX install, or you can do what I did which was boot into Windows 10 and use disk utility to adjust the partition. Windows of course being windows gave me stupid errors when I tried adjusting the partition size - but I found out it was because you have to disable the pagefile before you can adjust partition because a lot of your disk will be in use as virtual memory. This is a BIG TIP so make sure you make note of it, otherwise you will have issues.

In my case I kept 100GB for Windows 10 and put the other 400GB for OSX.

The steps in this guide will be very helpful for you, as your have to FIX dual booting after your OSX install so that clover boot loader loads where you will be able to pick Windows or OSX.

If you get stuck I can try to help, but make sure you do some searches and read some guides. Everything you need will be there already for the most part.

Good luck.

I want to install on a partition . That means I have to create it first using my windows then at the time of installation of Mac os just have to select it and change its format . That's it right ? And but how can I dual boot between windows And Mac os . I want without deleting my existing windows . I found on forums that we must format whole HDD and then install Mac os and after that windows . But the main reason I don't want to do this that I have my big games on windows and don't want to redownload .
Thank you

Yes you got it, create the partition in windows first, then after once you boot up with your Mac OSX USB boot stick (make it with UniBeast) you install the OSX to the new partition and leave Windows partition alone. You will not delete the Windows partition don't worry, unless you mistakingly install OSX to the Windows partition. Just be careful with the steps you are taking.

You should not have to format your disk as suggested on the forums if your partition is using GPT. If it is using MBR then YES you might have to format it and reinstall windows - but there are probably some Windows utilities that can convert partition types.

First things first, determine which type of partition you have by looking in Windows disk manager.

Once you have GPT as your Windows partition, then you can proceed with the steps we've been talking about. Once your OSX is properly installed, by leaving the USB boot stick in your computer you will actually be able to select booting between Windows and OSX.

The next step in hackintosh building is to get your computer to boot without the USB boot stick. This is done in the final step of your install which is outlined in many of the guides here on the forums that you should read through them so you understand all the steps. Basically in this step you want to put your boot loader (Clover) to the computer hard drive so you can boot without the USB stick, and this will also let you select between windows and OSX after.

To dual boot between Windows and Mac OS you will replace your boot loader with Clover boot loader which lets you select between Windows and OSX. It's simple. Those steps I provided in this link where it says "FIX DUAL BOOTING" : https://www.tonymacx86.com/threads/dual-boot-on-a-separate-drives-or-the-same.208086/#post-1377570

Fix Dual Booting

1. At this point, the machine will be booting only to Windows. Insert your El Capitan install USB drive and restart. Use F12 if needed to boot to the USB.
2. You should see a Clover menu. Select Boot Mac OS X from YourDriveName.
3. Once in OS X, mount your EFI partition with EFI Mounter v3
4. Go to the EFI partition
5. Go to EFI/Microsoft/Boot/ and rename bootmgfw.efi to bootmgfw-orig.efi
6. Copy EFI/CLOVER/CLOVERX64.efi to EFI/Microsoft/Boot/bootmgfw.efi
7. Eject the El Capitan install USB drive
8. Reboot
9. You should get a Clover menu, with the usual settings to boot to OS X and also new Windows options. To start Windows, select Boot Microsoft EFI boot menu from EFI.
10. After future Windows updates, Windows may reset the EFI partition to boot only to Windows again. You'll need to repeat the steps in this section.

You should now be able to boot to both Windows and OS X!

Ok . So I have got to know that I have created the bootable usb for uefi . After I checked my pc info . I got to know it's legacy . After checking in my bios . They had given options SELECTED AS *(Legacy+UEFI)* and (UEFI) was in option. Which one should I select . Also my partition style is MBR . Suggest me how to change it too Without losing my data . And do I need to change my all 4 partitions (including a 500 mb partition automatically created by windows) to GPT or just one which I'm about to install the Mac osx . You are great bro
Thank u!

After checking in my bios . They had given options SELECTED AS *(Legacy+UEFI)* and (UEFI)

Pick Legacy and UEFI, but when you created bootable USB with UniBeast you had to select which one was suitable to the selection you make in bios. But anyway Legacy + UEFI should work.

You can't have any partition that is MBR, at all, even if it's the Windows one. So you can not install osx until you address this issue. (you can try but I read that it's not recommended and may cause problems later)

To change partition type:
If you use Google, search for some free software that might be able to change your partition type.

Other option is copy your steam folder to another drive (trust me this works I have done it a million times) and format your drive, reinstall Windows with the right partition type, then copy your steam folder back, install steam. Steam will recognize your downloaded games and you will not have re- download any games at all.

Let's be honest, Windows needs to be reinstalled / cleaned every 3-6 months anyway
