Booting Windows Vista RTM in UEFI Mode (Not Fake!)

[Asteriminette]

Hi guys. I've found Microsoft lied to us. This may be first in the world which can installed RTM with UEFI. First, I've looked into Spanish, Greek, English and Turkish ISO files and I saw that "bootmgr.efi" file and "EFI" folder. Then, I opened inside of install.wim file with 7-zip. I saw \Windows\Boot\EFI folders and I've took whole folder. Next, I've created "Boot" folder inside "EFI" folder on USB. After that, I've extracted \Windows\Boot\EFI folder into "Boot" folder. Finally, I've renamed "bootmgfw.efi" to "bootx64.efi."
Thanks for reading this guide. I hope you liked this topic, thanks.

Already known fact. Here we use these files to boot XP64 in UEFI mode with more or less success.

Hmm, maybe. Because I believe the I don't installed UEFI mode in first place. Thanks your comment.

but it has always been known that UEFI mode can be started from Windows Vista / Server 2008

Is there a way to boot 32-bit Windows Vista RTM using UEFI?

Using beta files, you can boot Vista 32bit in 32Bit pure UEFI platforms (so far i have only seen some Acer's and "bailtrail" (baytrail ) nettops offering that). What you can't do is boot 32bit vista versions in the more common UEFI 64bit machines using these files. Unlike BIOS boot, you can only boot 32bit OSs in 32Bit UEFI machines, and 64bit OSs in 64Bit UEFI machines. In pure UEFI boot mode, firmware bitness has to match OS bitness.
