Error: Not Found while loading legacy loader

[Frank Schreimel]

Hi,

I want to use on my MacBook Pro (early 2015), with OS Sierra, Windows 10.
I created an bootable 500 GB SSD, which I connected with USB 3 to a Windows Computer. I used "WinToUSB" to get the format VDHX.
Afterwards I changed my MacBook Pro into the recovery mode and typed in the terminal csrutil disable. Now I installed rEFInd 0.10.4 and tested it, it works.
Now I connected the SSD by Thunderbolt 2/USB 3 with my MacBook Pro.
I rebooted the MacBook and now i can choose the OS Sierra or Windows, but when i choose Windows I get an Error code.

This is my boot screen.

If i want to boot the Windows SSD by Thunderbolt 2 connection.

and this with the USB 3

My SSD: TS512GSJM500

Regards

Frank

Hi, I just tried this myself yesterday using a Windows-To-Go 32 bit Windows 10 installation prepared using AOMEI partition tool, and I am getting the same issue.

I just tried again using a different method suggested on reddit which recommends using the WAIK tools. It seems I executed the steps correctly but unfortunately the drive is still not recognized as bootable by my 2015 MBA and rEFInd produces the same failure message

You're trying to boot Windows in BIOS/CSM/legacy mode. This has always been a little bit iffy, and it seems to be becoming more problematic as time goes on. (rEFInd's BIOS-mode boot code for Macs was inherited from rEFIt. It's poorly documented, so I don't understand it and I don't know how to maintain it.)

I suggest that you make a USB drive that can be booted in EFI mode rather than in BIOS/CSM/legacy mode. To do this, you'll probably have to either use a different tool to create the USB drive or locate and adjust some boot-mode options in the tool you're using. I'm not familiar with WinToUSB, and I have no idea what the "VDHX" option you mentioned does. I recently built a Windows 8 installation USB from a Microsoft .iso file using Rufus, and it worked fine for me on a UEFI-based PC. (I did not try it on a Mac.) You might also want to see my page on the perils of the CSM. Although that page is written primarily for UEFI-based PCs, much of it is as applicable to Macs.
