Problem installing W10 on BCA 6 and El Capitan 10.11

Hi, I have problems installing W10 on my Mac.

Here's an overview of what happened:

OS X Yosemite, with W7 Bootcamp (everything is fine).

Updated to OSX El Capitan, Bootcamp no longer found (holding alt on boot doesn't show Bootcamp).

Used BCA to Remove Windows 7 or later version. (space allocated in HDD for Bootcamp is back to single partition).

Used BCA to Create a Windows 7 or later version install disk using Win10_English_x64.iso downloaded from Microsoft along with latest support drivers from Apple. Also checked Install Windows 7 and or later version.

After waiting a couple hours and the USB Bootcamp is finally ready, I set 70gb for the Bootcamp partition, eventually the Mac automatically reboots but never booted up to the Windows 10 bootcamp installation (The reboot is just like any normal reboot that reboots back to Mac).

Opened BCA and it now shows Remove Windows 7 and or later version.

Checked Disk Utility, and the partition for Bootcamp is there but most of it is unused.

What could be the problem here? I also noticed that my BCA is still showing Windows 7 while I've read somewhere that on El Capitan, Bootcamp no longer requires USB Drive, or atleast shows Windows 8. http://blog.twocanoes.com/post/130203487014/apple-boot-camp-no-longer-requires-u sb-flash-drive?utm_source=loopinsight.com&utm_medium=referral&utm_campaign=Feed% 3A+loopinsight%2FKqJb+(The+Loop)&utm_content=FeedBurner

Checked the Win10_English_x64.iso for MD5 and SHA1 and everything is fine.

OS X El Capitan 10.11

MBP Retina 15" Mid 2014

Thanks in advance!

Can you remove the partial installation and start over? You may not gaining insight into failures. Please also run SMC and NVRAM Reset after you remove Windows.

Yes I am able to remove the "installed" partial bootcamp, like so.

Same result, it reboots automatically but doesn't boot to the Windows 10 installation, instead boots back to El Capitan. This was after doing a successful NVRAM Reset (CMD+ Opt + P + R, Second Chime). Wasn't able to pull of a successful SMC Reset though, Shift + Opt + Control + Power doesn't do anything.

How it looks like on, Disk Utility:

Thanks for your help! I see you a lot in these Bootcamp troubleshooting! Appreciate your help to us!

Your Mac 2014 is a UEFI model, you can install Windows without BC Assistant. Create a Free Space part using Disk Utility, use the W10 USB installer and select EFI Boot using Alt/Option. The Free Space will be split into MSR (128MB) and remainder as MSD (NTFS). Do you want to try this method? EFI boot is a faster than the older BIOS/MBR method.

Haven't tried installing Windows this way, but I am willing to try..

By Creating Free Space part using Disk Utility, I'm assuming this is done this way? Did i get it correctly?

What format should the Free Space be in?

As for the W10 USB Installer, can I use the one BCA made? Or are there any specific process involved that I should follow?

How do I proceed with "select EFI Boot using Alt/Option.". I assume this is done by holding Alt/Option on boot with the W10 USB Installer plugged in? Did that earlier, the Boot selection only shows Untitled (which is OS X 10.11) and wasn't detecting W10. Sorry, was new with this UEFI/EFI thing, always have installed Windows using BC. Thanks for your patience and help!

1. Click on the Format drop down list and look for Free Space. Free Space does not have a file system.

2. Yes. As you can see, you have a bootmgr.efi. This will show up as EFI boot. Your Alt/Option steps are correct.

I can't seem to find "Free Space" in the format dropdown list, I think it has to do with El Capitan.

Create FAT32. We can convert it to Free Space, if necessary. From a Terminal can you run the following command

diskutil listfilesystems

Formattable file systems

These file system personalities can be used for erasing and partitioning.

When specifying a personality as a parameter to a verb, case is not considered.

Certain common aliases (also case-insensitive) are listed below as well.

Create a FAT partition. Run diskutil list. Find the disk which has the space allocated. I suggest you name is BOOTCAMP.

Once you find the correct disk0sN - N points to your specific slice, you can run...

diskutil eraseVolume free BOOTCAMP disk0sN

I have successfully made a Free Partition

However I don't see any option of booting up when holding Alt/Option on reboot, I only see Untitled (OS X). The Win10 USB is plugged in

If you hold Alt/Option, do you see any USB entries? If yes, do you see an EFI Boot? Select it.

No USB Entries, just "Untitled" just how it shows up on Startup Disk. I was holding alt/option during boot (chime sound) with Win10 USB plugged in.

Can you post a directory listing of the USB from Finder? With the USB connected, can you also post the output of

diskutil list

sudo fdisk /dev/diskN, where N points to the USB.
