This issue was reported by Mr.X on forums.mydigitallife.info.

Basically, if you try to install Windows x64 in UEFI/GPT/NTFS, you will get either the message (removable disk):

Windows could not prepare the computer to boot into the next phase of installation. To install Windows, restart the installation.

or (fixed disk):

Windows installation error 0xc0000005

when Windows setup tries to start copying the files.

This is due to Rufus setting the type of the UEFI:TOGO partition to EFI System, and Windows setup creating another EFI System partition, but expecting only one EFI System partition for the whole system.

The reason Rufus chose to set the UEFI:TOGO partition to EFI System was for increased EFI compatibility, but clearly this wasn't a good choice. Will need to revert the type of the partition to Basic Data, and hope that all UEFI firmwares can list and boot from a partition that contains the expected EFI boot loaders, regardless of its type.

And?

Also, please don't hijack an issue that pertains to a different problem(?) to report something else.
The original issue only applies to UEFI/GPT/NTFS. If you're not using UEFI/GPT/NTFS and have an issue during installation, you should create a new issue.

Hi pbatard, I believe this actually fixed the Windows To Go booting issue I was having in #450.

I didn't remember the specific error message until it was mentioned.
"Windows could not prepare the computer to boot into the next phase of installation. To install Windows, restart the installation." was actually what I was getting after booting to the Windows To Go installation. (UEFI/GPT/NTFS) I was able to boot successfully without error after formatting with 2.1.649.

Hello,

I was wondering if someone can shed some light how to revert the partition to basic data on OSX. I am getting the same error message " Windows could not prepare the computer to boot into the next phase of installation. To install Windows, restart the installation. " Do I need a windows computer for this?
Thanks! Thanks!

Ok. Fixed the issue by partitioning the drive using the option 'empty' which is on the drop down in Yosemite partition menu and then formatting the drive again with the windows installer. I am using bios UEFI. Anyway, thanks!
