Install Mac is high Sierra (10.13) without erasing windows 10

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

Bro what about Games Like Forza Horizon 3 And so . I can't reinstall it because it's a pain to download 55 GB and I don't have that much data . I have downloaded it from Windows store and don't even know where it is stored . And yes I have windows iso on my computer so I can create a bootable usb but should I install Mac os first or windows ? And MBR can be changed by some softwares as referred on YouTube . So should I back up my few important data and games first then try it and tell me how can I back up my Forza horizon 3 lol

Thank u !

A big question in my head . Why I need to convert MBR into GPT ? Because in YouTube videos they just don't say this thing and what's the relationship ?

Not sure about the videos, who knows maybe I did not understand the requirements.

Read these guides and post question in appropriate thread, maybe someone can confirm:

https://www.tonymacx86.com/threads/guide-booting-the-os-x-installer-on-laptops-with-clover.148093/

What I read was this:

Summary:
- OS X requires GPT, so if your Windows install is legacy, must convert to UEFI/GPT
- OS X doesn't like the MSR partition, so you have to remove it
- OS X requires 200+mb EFI partition, so if yours is smaller, must increase the size

But my motherboard is already UEFI right? And about all the YouTube videos haven't mentioned about MBR or GPT. When I Tried To Boot The USB into my computer, the apple logo got stuck in the starting and the line was not moving . Any BIOS setting for this? Also check this

He tells how to install macOS. He didn't mentioned about MBR or so.

He doesn't mention partition type because it's not a very detailed video. He skips some information. Add the -v boot argument so you can see where it's stopping. Also if you have Nvidia card, you need to add nv_disable=1 boot argument as well. Or, just pull the card out for now and use graphics chip on motherboard if you have one to get by the installer.

@RehabMan I read the guides and understood it that NO partition (even the Windows 10 one) can be MBR if booting with clover. In other words, ALL partitions on the drive should be GPT. Can you verify this? Its a bit ambiguous and hard to understand if its only referring to the NEW partition for OSX, or ALL partitions on the drive.

thx.

Individual partitions are neither GPT nor MBR.
Partition scheme is an attribute of a block storage device (eg. disk), not an attribute of a partition.
A disk is partitioned with a particular partition scheme (for your purposes, GPT).
Then individual partitions within that disk are formatted with the desired file system format (NTFS, HFS+J, ext3, etc).

@RehabMan ok thanks for clarification! cool

hook up a USB mouse and you might need USB keyboard if it's not detecting your laptop keyboard.

I had to do the same on my ASUS for first install.
