It took me some time to get everything in order and I made several mistakes I would like to share. This is the best write up about installing Win 7 in EFI mode I could find. R3loaded thank you for such comprehensive post. Run "notepad \Windows\Panther\setupact.log", and the log will show: When you see the Install welcome screen, hit Shift+F10.There are now two methods to verify that the installer has indeed booted in EFI mode: That's it! No need to write boot sectors or anything like that - as long as you have a FAT32 filesystem with a \efi\boot\boot圆4.efi file, the computer should pick that up and start booting. It should automatically boot with the UEFI method, but you may have to specifically choose UEFI boot depending on your system. Copy the bootmgfw.efi file to \efi\boot, and rename it to boot圆4.efi.Copy this directory one level up so the files also reside under \efi\boot. In the root of your USB drive, there is the \efi\microsoft\boot directory.This is pretty much all Sandy Bridge systems (except for Gigabyte motherboards) and some new laptops. A system with native 64-bit UEFI 2.0 firmware.Alternatively, you can download a copy from here. You can obtain this from an install of 64-bit Windows 7 - look in C:\Windows\Boot\EFI.
Ensure that the drive correctly boots on a BIOS system. 4GB USB boot drive with Windows 7 64-bit installer - there are plenty of guides around the internet for creating one.However, if you create a USB boot drive for the Windows 7 installer, the system will only boot in BIOS mode, and the installer will not let you install in EFI mode to GPT disks.Īfter a fair bit of googling and general hacking around, I've managed to get my P8P67-M Pro to boot the Windows installer from a USB drive in EFI mode. Booting the installer from the DVD will apparently boot you straight in EFI mode as you'd expect (I don't have Windows on disc so I wouldn't know).
I got my replacement SSD at the weekend, and I wanted to install Windows so that it would take advantage of the native UEFI firmware of my Sandy Bridge motherboard. Just copy the entire contents to a FAT32 USB drive and it should boot correctly in native EFI mode. Windows 8 users: This stuff is now unnecessary.
