There is nothing like GPT ISO file, GPT is a partition style of hard drive. There is no pre-activated ISO, If you have product key to the particular Windows ISO version you're downloading (in case of Win 7) - you can activate it with the activation key you bought from Microsoft or printed in COA LABEL/ OR in case of pre-installed Win 8.1, key will be automatically activated on installation. Dec 22, 2014  Demonstrate how to create a UEFI Boot Disk for Windows 7 on a USB Thumb Drive or USB External Hard Drive. Below are the step by step instructions. HOW TO CREATE A UEFI WINDOWS 7 USB BOOT DISK 1.

I've been trying to boot up my Win7 USB stick into EFI mode as the disk I want to install it on, is GPT. I have tried to modify the installation media (including copy bootmgr.efi, bootx64.efi and such), but I keep getting a winload.efi file is missing error, which is a bit weird because setup disks aren't supposed to have a system32 folder containing a winload.efi file.

My Motherboard certainly supports EFI boot. When inserting my flash drive, I get two options for boot, one bios and one UEFI. Also, I've installed Win8.1 on a GPT disk, as well as a previous win7 install, which I seem to have forgotten how I managed to make it work.

I've tried going through a lot of topics, and the entire idea about EFI boot using files still remains very foggy in my head.

So I w would really appreciate it if I get a clear idea of how EFI boot works in this case(more from the perspective of what files are needed):

  1. What are the files needed for EFI boot for a windows setup USB?
  2. What files have been renamed but are actually similar files? (such as bootmfgw.efi and bootx64.efi)

And the purpose of the other folders/files(correct me if I'm wrong):

  • sources: files Windows needs during installation, including the .wim file.
  • boot: BIOS installation boot files
  • support: additional tools
  • autorun.inf, setup.exe: Files needed for Autorun

My motherboard also has an option to Launch EFI shell from file system device, requiring it to have a shellx64.efi file. Is this the same as the bootmgr.efi file? Will copying/renaming it work?

prepare usb stick with rufus and point it to the windows iso, selecting gpt and fat32. rufus will prepare and populate the efi/ directory on the stick, so you can install windows 7 in efi mode.

After a bit of tampering with additional ISOs, I've realized that you can just replace the sourcesinstall.wim file on a Win 8/8.1/10 bootdisk with the one from Win7 to make it work.

  1. Just get a Win8/8.1/10 ISO
  2. Open it using an ISO-explorer (like UltraISO)
  3. Replace sourcesinstall.wim with that from the Win7 ISO/DVD
  4. Save as a new ISO, and/or burn it into the installation DVD or on a USB/external HDD active Fat32 partition.

The installation UI will be of the bootdisk's Win version, but it will certainly install Windows7.

Conclusion: Perhaps, (my) Windows 7 efi boot files are just.. broken.

I have been trying to build up a window's 7 and 2k8 EFI deployment ISO or USB. But struggling to to even get an ISO to boot from even VMware Workstation EFI implementation. The problem is there is no clear requirement to what the EFI bootloader is looking for, 'e.g EFI boot file' even ISO's and USB's that are bootable don't find the required .efi file.

I'd like to know what is the process EFI bootloader follows to boot the EFI file. e.g; Djvu viewer mac free download.

in a EFI windows system its; C:WindowsBootEFIbootmgfw.efi

Efi

From DVD it's; F:efimicrosoftbootcdboot.efi

from what people tell me it's on USB; G:efibootbootx64.efi (bootmgfw.efi renamed)

I've been testing on a HP notebook with EFI 2.0 and VMware Workstation 8.0 with .vmx file firmware = 'efi'
