Step 2. Open an “Command Prompt” and run “DISKPART”.
This will launch the diskpart utility in a separate windows and perform a UAC prompt.
Step 3. Type “LIST DISK” and take note what the disk number is of the USB memory stick. This will be the same size as the USB memory stick (eg. 3824 MB = 4 GB).
Step 4. Then type “SELECT DISK X” where X is the disk number of the USB memory stick.
Step 5. Type “CLEAN”. Warning – This will wipe all data from the USB memory stick.
Step 6. Type “CREATE PARTITION PRIMARY”
Step 7. Type “SELECT PARTITION 1”
Step 8. Type “ACTIVE”
Step 9. Type “FORMAT FS=FAT32” (and wait about 5 minutes depending on the size and speed of the USB memory stick)
Step 10. Type “ASSIGN”.
You will notice the auto play window now appears. Take note of the drive letter (e.g. F:\ ) and close this window.
Step 11. Type “EXIT”
Step 12. Back at the command prompt type “xcopy d:*.* /s/e/f F:” where D: is the drive letter of you DVD and F: is the drive letter of your USB Memory stick.
Don’t worry if it takes a long time to copy boot.wim and install.wim as these are the two largest files on the DVD.
Step 13. Once the xcopy is finished run “del F:\sources\ei.cfg” from the command prompt and you Windows 7 Bootable USB memory stick is ready to go. Doing this step is what makes the USB memory stick allow you to install any version of Windows 7 as it no longer has a default version configured.
You can now either boot from the USB memory stick or just run setup.exe from the drive to start the install process. Either way you will now prompted for the version of Windows 7 you want to install.
