How to install Windows 7 in UEFI Mode with a USB

Hey guys, I've never seen a full guide to installing Windows 7 in UEFI mode before anywhere, trust me I've looked. But I managed to pull it off a few days ago. So I thought I'd share it with you guys

What you'll need:
A Windows 7 64 bit ISO (doesn't matter what edition and can be an All in One disk.)
Virtual Clone Drive (To Extract ISO Contents)
8GB+ USB Stick
A UEFI BIOS
7-Zip
A Computer already running Windows

Steps:
1) Install Virtual Clone Drive Link Here and also install 7 zip Link here

2) Make a flat copy of your windows 7 x64 ISO, which mean just extract the contents of the ISO into a folder. First you'll want to mount the Disk Image, by right clicking and mount to Drive E: for example.
Mounting Image Example

Next open the disk drive you mounted it to, and copy the contents to a place you'll remember. (This will take a while)
When it's done it should look something like this

3) Format your USB Stick.
Just go to computer, right click it and press format. Make sure you change file system to FAT32. This is so you can boot from it.
Settings for formatting

4) Now here's the hard part. Preparing the flat copy for UEFI.

Go to the EFI folder, make a new folder in there called "boot".
Now go into the "Microsoft" folder which is in the EFI foler. Then boot, and copy the contents.
What it should look like
Put that into your boot folder you just made.

Now that's done. Go to the Sources folder which is in the root Here!
Scroll down to boot.wim, and right click, 7 zip and open archive.
Now go into the folder called "1" Example Image
Go to Windows > Boot > EFI
Scroll down till you see bootmgfw.efi and extract this to your desktop (click on it first, then press extract button at the top)

Now cut that file you extracted to your desktop, and put it into EFI > boot.
Where to put the file

Once you've done that, just rename it to bootx64.

5) Now you've prepare the flat copy for booting from UEFI. It's now time to prepare your USB. This is relatively simple but pay attention YOU COULD ERASE A DISK BY ACCIDENT. So unplug everything you can, but the usb to be sure.

Open a CMD Prompt. Start > Accessories right click command prompt and run as admin.
Now type "Diskpart"
Diskpart Example

Now type "list disk"
List Disk Example

CAUTION: When selecting a disk, make sure it's your USB. Look at the size of the disk.

Now type "select disk and then the number of your USB. For example mine is "Disk 2"

Next, type "clean" and this will format the drive.

Now type "convert gpt" and this will make it into GUID Partiton Table (if you don't know what this is google it xD)

Next type "create partition primary"

And then type "format fs=fat32 quick"

Then type "assign"

And now type " list volume" and it should list your USB and state it's drive letter.

6) Copy all the contents from the Flat copy you prepared earlier.
Example Here

Congratulations you have created a bootable Windows 7 UEFI USB!

Next I'm going to teach you how to install it in UEFI Mode.

1) Boot from your USB. There will be a certain button in which you can boot with such as F11, just look for a boot menu key. If there is not one, see if you can go to the boot tab in your UEFI BIOS and select a boot from there, or make the USB first priority.
2)Once you've got it to boot, select your language, currency and time region also your keyboard layout.
3) Click, next and click install now!
4)Choose a version, if you have an All in One disk.
5) Accept the license terms
6)Click Custom (Advanced)
7) Now from here press SHIFT + F10 to bring up a Command prompt window.
8) Type "diskpart" into the Command Prompt
9) Type "list disk"
10)Look for the size of your Hard Drive, and then type "select disk 0" for example, this maybe different for you, just look at the size of the different disk, one should be your USB and one should be your Hard Drive.
11) Next type "clean"
12) Type "convert gpt"
13) Close Command Prompt, and click Drive Options (Advanced)
14) Click "New"
Example Screenshot
15) It should come up with your disk size and hit apply.
16) A prompt will up asking you if you will allow windows to create system partitions, click OK. It should create another 2 along with your primary partition.
Partitions Example
17) Click Next and begin install your Windows 7 Copy. You will not need to do anything now just sit back and relax!

Ways you can check if you've done it properly are:
1)Them two partitions were created (System and MSR)
2) Go to computer and right click your C:/ drive. Click the hardware tab. Click your Hard Drive and click properties at the bottom.
Example Here
Now go to volumes and hit populate (you will need to turn off UAC otherwise it will not work) click the volume (it will be the only thing in the box)
Picture for volumes
Now you will notice that the Hard Drive has a partition style of GUID (GPT) which mean you've done it!

Thanks for reading this guide, hope it helped you. Took me around 1:30 mins to type this out. So yeah, hope you enjoyed this!

I'm a little confused here because in that tutorial, in Step 11-C says to extract the bootmgfw.efi file from sources\install.wim, and in the OP's instructions says from sources\boot.wim.

Which one is the correct form?


Thanks and greetins!

Thanks for your prompt response Brink! I'll try later when I'll arrive at home.

In fact, I posted a question in that tutorial too. Do you think you can take a look at it please? Although I quoted a question from theog, maybe you know the answer.


Thanks and Greetings!

The tutorial states
"Once you've done that, just rename it to bootx64."

Rename what??
and for once doesn't provide a screenshot


What are we renaming to boot64?

  1. The boot FOLDER?
  1. or the bootmgfw.efi FILE we just copied? making it "bootx64.efi"

Hello Danielsan16,

You need to have a Windows 7 64-bit USB flash drive that is compatible with UEFI mode. As long as it is FAT32 formatted and has \efi\boot\bootx64.efi file, it should be UEFI bootable.

The easiest method to do this, would be to use Rufus: Rufus - Create bootable USB drives the easy way

NOTE: Rufus automatically creates the boot folder in the efi folder and puts the bootx64.efi in the folder.

Thank you so much for this! Installing Windows 7 Enterprise on a new Lenovo X1 Carbon (4th Gen), this worked like a champ.

The only thing I did differently is get Intel's USB 3.0 Creator Utility and let that install the USB 3.0 drivers into the install USB you helped me create.
