# Create a primary partition (using MBR). # case, issue this command to change it to the MBR layout. # above will show an asterisk in the last "Gpt" column. # If the USB drive is using the GPT layout, the "list disk" command output # Delete all partitions, resulting in a blank disk. # Show all disks (aka drives, like hard drives or removable media).ĭISKPART > select disk Run the following commands in the DiskPart utility (ignore the comment lines marked by the pound # character):.You will be prompted with a popup message asking “Do you want to allow the following program to make changes to this computer?” Answer Yes. ![]() Launch the “diskpart” or “diskpart.exe” utility from the Windows Start/Run menu or the Command Prompt.(The 64-bit Windows 8.1 Professional ISO image I had is 4.5GB in size and requires at least an 8GB USB flash drive). Insert a USB flash drive with sufficient capacity.To create a bootable USB flash drive, do the following: The UEFI specification requires bootable removable media (such as a bootable USB flash drive) to use the MBR layout and FAT32 format. In addition to BIOS+MBR, UEFI also supports the new GPT (GUID Partition Table) layout. The BIOS boot method uses the MBR (Master Boot Record) layout. (When folks say EFI, they are usually referring to UEFI because all modern computers use UEFI.) UEFI is a replacement for the previous BIOS method of booting up, but UEFI still supports the older BIOS method. If you are interested, here’s the technical reason why our bootable USB flash drive will use the MBR layout and FAT32 format: Computers, including both Windows and Macs, boot using a standard called UEFI (Unified Extensible Firmware Interface), which is based upon the EFI specification (Extensible Firmware Interface). ![]() Specifically, I will be using Windows 7’s built-in DiskPart (Disk Partition) command-line utility to create a bootable USB flash drive containing a Windows 8.1 Setup image. The instructions below will create a bootable system partition on a USB flash drive, which is exactly the same as creating such a partition on a hard drive.
