Guide: MultiBooting UEFI

[bruno03]

I updated the BIOS and my Clover boot option was gone, but this worked for me:

Thx. It worked.

 

[bruno03]

Actually it didnt. As soon as I boot into Windows, windows deletes that clover partition. So after restart I am only left with windows.

 

[bruno03]

Reinstalled whole thing again. Loosing my patience with this.

Now again. It doesnt work after booting. I got this new thing in clover - boot microsoft efi boot from efi. I like regular efi without boot. How to delete it?

This is for dual booting OS X Sierra with windows 10.

I already tried to delete partition 4 (W) and reformat the unallocated space to install windows but it wouldnt let me, it would give me an error and tell me it couldn't format the partition. I restarted, tried again and no good.
I know for a fact that it works when i simply reformat partition 4 instead of deleting it but the I cant get windows to boot from clover because their is no windows boot file on the EFI partition when I go look for it.
Any suggestions?

Make the Windows partition one of the first 3 partitions after the EFI partition
Make sure you are installing Windows UEFI mode -
insert install media in usb port / cdrw-dvdrw
boot and hit the hot key that allows you to select a boot device
you should see the Windows installer twice - once with UEFI in front of it and once without
select the one with UEFI in front of it and hit enter to boot it.

Ok cool, got everything squared away with the installation. But now I cant boot to clover. It takes be to a black screen with a bunch of commands for windows like selecting partition windows is in etc. In the bios, I dont see and UEFI option all I see is my SSD and Windows boot manager? advice?

I followed Rehabman guide for intel NUC i3 6th gen. I have only one SSD so first install macOS following Rehabman guide then partitioned the SSD into half for windows 10. boot windows 10 usb to install. once install complete then shutdown. plug clover usb and boot, selected macOS to get into the desktop. renamed the bootmgfw.efi to bootmgfw-orig.efi and reinstalled clover to eft partition. shutdown and removed clover usb. boot system and got a "boot drive not found" message.

now renaming bootmgfw-orig.efi back to its original, I can boot to windows 10 without any issue.

Any idea what could have happened?

Thanks.

I've installed MacOS Sierra, and haven't had any issues with it. It took me a bit to get it to work with my specs, but after I got it installed, it's been running like a champ.

I'm trying to install Windows on a separate partition from my MacOS partition, and I'm getting close, but no cigar.

Method 1:
I created the partition for Windows in MacOS, then booted to my Windows USB (created using the Windows creation tool on a Windows PC) and started going through the installer. I deleted the partition I created for Windows, and selected the unallocated space and clicked next. It then pops up and says that it couldn't go to the next phase, and to restart the installation. I try that, but it says it could find an existing partition or create a new one.

Method 2:
Created the partition and deleted it as above, but then I selected it and clicked "new" and it created all the partitions properly. I then selected the system partition it created, and clicked "next". It went to the installation screen, but it pops up and says "Windows detected that the EFI system partition was formatted as NTFS. Format the EFI system partition as FAT32, and restart the installation."

And I'm out of methods.

Any ideas? I've tried doing the same on another drive, but I get the same result.

Did you boot to UEFI and make sure the Mac OS was set as first in BBS boot order?
