How to Create a Self-Installing Bootable USB Key to Install an OS
- 1). Insert the USB key into one of your computer's open USB ports.
- 2). Open the Start Menu and type "diskpart" in the search field at the bottom. Press "Enter." Windows displays the command prompt and runs the DiskPart utility. The window displays the prompt "DISKPART>".
- 3). Type "list disk" and press "Enter." The window displays a list of the computer's storage devices. Record the number in the "###" column for your USB key; this device should display a number such as "4 GB" in the "Size" column, as opposed to a much larger value, such as "120 GB" for your computer's hard drive.
- 4). Type "select disk (number)" and press "Enter," where the number is the one you recorded in the previous step. For example, the completed command might read "select disk 2."
- 5). Type "clean" and press "Enter." This operation removes the current partition from the USB key, so make sure you have removed all data from the device you want to keep.
- 6). Type "create partition primary" and press "Enter." This command creates a new partition on the USB key.
- 7). Type "active" and press "Enter." This command makes the new partition bootable.
- 8). Type "format fs=fat32 quick" and press "Enter." This formats the partition, making it possible to save data on it.
- 9). Type "assign letter=e" and press "Enter." This gives the USB key the drive letter "E:" in Windows. If you already have a drive with that assignment, use another letter.
