    I am having some problems with this tutorial.

    I tried the windows 8 version and it worked fine. I had some issues with windows 8 (unrelated to this tutorial) and decided to install windows 7 UEFI. I have followed every step to the letter and I can not boot to UEFI with my usb. I have even tried installing windows 7 from the oem dvd that I have. It shows up as uefi, but will not boot either. I do not have a screen shot of the error message, but it is:

    Windows failed to start. A recent hardware or software change might be the cause. To fix the problems:
    1. Insert your windows installation disc and restart your computer.
    2. Choose your language settings, and then click "next."
    3. Click "Repair your computer."
    If you do not have this disc, contact your system administrator or computer manufacturer for assistance.

    File: \efi\microsoft\boot\bcd
    status: 0xc000000d
    info: An error ocurred while attempting to read the boot configuration data.

    If I disable the legacy mode in the bios it will not boot. I have tried it on two different computers with the same results. The regular usb mode will boot (non-uefi). I tried the suggestion from earlier in the thread where you make a folder called boot in the efi folder and only copy bootx64.efi and that has basically the same effect. The difference is that now it will boot from the uefi usb, but only with legacy enabled.

    I have read multiple tutorials and they all give the same directions, so I am sure that it should work, but I can not seem to make it happen.

    I have not tried turning off fastboot in my bios at home, but the bios that I am trying on in my office does not have fastboot enabled. Neither bios has secure boot enabled.

    What else can I try?

    Hello Wikedeye, and welcome to Eight Forums.

    Just to verify, are you using a 64-bit Windows 7?

    Are you wanting to replace Windows 8 with Windows 7?

    If so, then you will need to do the tutorial below first to "clean" (delete) the hard drive and convert it back to MBR first.
    If not, then please post a screenshot showing the full layout of your Disk Management along with what is what, and we'll go from there.

    I have been trying to duplicate the error message, but have been unable to do so. My flash drive is either ignored, or boots normally.

    I did see that error once when I was testing years ago, but I do not remember what caused it.

    I was wondering, however, why you show a Modified date on your folders on the Flash drive as today. Every way I have copied the files to the flash drive, they have maintained their original Modified Date. So how did you copy them to the drive?

    Also, once you get the "efi\microsoft\boot\bcd" message, it might be advisable to start over and redo the Flash Drive.

    Edit: Using an 8 GB flash drive, if you are not currently doing so, maybe not help, but couldn't hurt.

    I am currently running windows 7 on the machine in question. I prepared the drive through CMD before installing windows 7. I previously had win 8 on this drive, but I formatted it and started fresh trying to install win 7 uefi. Here is a shot of my disk management screen and a shot of msinfo32 (not sure if it is helpful, but info is good).

    To answer questions about my usb creation methods:
    I started with an oem windows 7 64bit install disk. I copied the files directly onto a prepped usb drive. Then I added the "boot" folder to the "efi" folder and copied the contents of the boot folder under efi\microsoft\boot. Then I changed the bootmgfw.efi file to bootx64.efi and added it to the efi\boot folder. This did not work. After this failed I downloaded a retail .iso thinking maybe the oem version was the problem. I extracted the .iso files to my hard drive instead of directly to the usb (maybe this is the problem). I repeated the steps above. I have reformatted and re-made this usb 7 times at this point. I am pretty sure that I am not missing any steps or doing anything incorrectly. I have also tried three different usb drives. They are all kingston data travelers (two are 8gb and one is 16gb).

    While at work I burned a copy of the downloaded iso and it shows up as a uefi bootable disc under the boot options with legacy enabled. However when I turn off legacy the disc freezes at the windows logo.

    1) Do you have Secure Boot DISABLED?

    2) Your HDD is not partitioned for UEFI mode.

    Secure boot is not enabled.

    I know my HDD is not partitioned for gpt. It did not give me the option when installing windows 7 non-uefi. I did however prepare the drive through CMD for gpt installation, but when I got to that point in the non-uefi install it made me install in ntfs format.

    I feel like I am not setting my bios correctly, but I have tried on two different computers with two different bios', from tow different manufacturers.

    Wikedeye,

    Try having only the HDD that you are installing Windows 7 to connected. Next, do as Ray posted above to delete all partitions on it before clicking on Next. Afterwards, you should have the drive properly partitioned for UEFI as in the tutorial below.
