Guide: MultiBooting UEFI

Just a note - I had a similar issue - . "Could not go to the next installation step" When trying to install Windows on a dual booting ssd - the fix for me was to go into the BIOS and disable MBR protection.
 
Hi guys I have a 2 questions regarding multi-booting. I have macSierra set up on my hackintosh and I wish to also add Win10 onto the same SSD.

1. Is there anything I need to do (besides backing up my files) to add Win10 to my system? Or could i just follow the guide from the step where i partition my SSD for the Win10?

2. My USB installer runs El Capitan (i have updated the OS since). Will this pose any problems for me if I try to boot OS X using that USB installer. If it does, are there any steps I should take to overcome this?

1. Just follow the guide
2. So long as the USB is Clover boot and not Chimera it might work. Suggest you install the latest version Clover on the USB and test to make sure it boots OK.

Now, to make everything work right, shutdown Ubuntu, insert the OS X USB installer again and boot to OS X desktop. Mount the EFI partition and rename the Windows boot manager file:

Run MultiBeast to install Clover, networking and audio and reboot to UEFI and set the OS X partition as first in boot order:

Save&Exit and continue boot to Clover - select an OS to boot:

And that, my children is just how simple it is.

Same drive installation or separate drives? Your Mobo is Intel? What model?

Then show HP8300 Elite SFF in your profile.
There are several builds that use that machine - one of the Mods (PastryChef) has a testing platform built on it:

And there is a guide here: https://www.tonymacx86.com/threads/...lite-8000-8100-8200-8300-other-models.186726/

Those guides don't come with dualboot instructions, one guide exclusive for this motherboard referenced this guide.
 
@Takasur

Referring back to your earlier post - you say you have 2 efi partitions? Is this same drive or separate drive? If same drive this should not occur - only a single efi partition is needed.
