How to create UEFI bootable flash driveLukas Beran
New computers are supplied exclusively with UEFI. In the following article, I will describe how to create a UEFI bootable flash drive to install the operating system. The described procedure applies to both Windows 7 and Windows 8 (and newer) devices.
For installation you will need at least 4 GB flash drive and 64bit installation image or DVD with Windows 7 or Windows 8 (or newer).
- Connect the USB flash drive to the computer on which you will prepare the drive.
- Open command line with elevated rights (Run as administrator on the cmd.exe).
- At the prompt, type the following commands (replace # by disk number):MS DOS12345678diskpartlist diskselect disk #cleancreate partition primaryformat fs=fat32 quickactiveassign
- Close the command line window.
- Open the disk image. In Windows 8, just double-click the image (ISO file) – the image will be connected as another drive in Explorer. In Windows 7, use for example 7-Zip and extract the image to folder.
- Select all the files on the disk (CTRL + A), right click and select Send to – Removable Disk (your flash disk).
- Copy the efi\microsoft\boot to EFI location. In the folder EFI will be now folders microsoft and boot.
- On the installation image, go to the folder sources and using 7-Zip copy the file sources\install.wim\1\Windows\Boot\EFI\bootmgfw.efi to the location efi\boot on the installation USB drive. Rename the file to bootx64.efi. This step is not needed when you are creating installation drive with Windows 8 or newer.
UEFI installation flash disk is now ready.
