EFI boot Windows 10+Mavericks

I say it at the start of post. Booting win 10, appear:

Your PC needs to be repaired. The application or operating system couldn't be loaded because a required file is missing or contains errors. File: \windows\system32\winload.efi Error code: 0xc0000225

Sounds like your BCD store is damaged. Rebuild it with BCDBOOT.EXE as mentioned in post #4.

BCDBOOT.EXE writes on EFI partition or on Windows partition?

BCDBOOT.EXE writes on EFI partition or on Windows partition?

If the system is booted UEFI, it writes on EFI partition.

If the system is booted UEFI, it writes on EFI partition.

Any chance you can elaborate on how this can be done?

I'm receiving the same error that's posted when selecting Windows 10 from Clover Boot Menu

You should read the BCDBOOT.EXE documentation provided by Microsoft.

What do you mean by "selecting Windows 10"?
Did you install Windows in UEFI mode?
Did you select the entry in Clover which corresponds to UEFI Windows boot? (press space bar, you should be running bootmgfw.efi or bootmgfw-orig.efi).

Thanks for replying!

How do i make a Windows Bootable USB in UEFI mode? I've made both a CD and USB. Booted into UEFI mode with both - with the CD it gets stuck at 89/90%
With USB when i boot via UEFI i keep getting an error that says i can't install to the Windows Partition due to some GPT error/MBR error. (I've erased in GPT format via Disk Utility in Mac)

- I resorted to installing through Legacy mode via USB.

Is that where the problem lies?

With Windows 10, it is a simple matter of copying the contents of the Windows installer ISO to the root of a FAT32 formatted USB.

Yes, that's what i did.
Booted into UEFI mode via F12 and selected the USB: UEFI Kingston...
I then Format the partition and receive the GPT MBR error that i stated above

Perhaps you made the mistake of creating Windows partitions within Disk Utility. Doing so will cause Disk Utility to create an MBR/GPT hybrid partition scheme. Windows will see it as MBR. Windows UEFI supports only GPT. I think you see the problem...

The correct way to dual boot UEFI Windows is covered in the guide, post #2: http://www.tonymacx86.com/threads/guide-booting-the-os-x-installer-on-laptops-with-clover.148093/

Always read carefully.
