Insert your Windows7/Vista DVD into the optical drive and check the drive letter of the DVD drive. In this guide I will assume that your DVD drive letter is “D” and USB drive letter is “H” (open my computer to know about it).
Maximize the minimized Command Prompt in the 4th step.Type the following command now:
D: and hit enter then CD BOOT (where “D” is your DVD drive letter)
BOOTSECT.EXE /NT60 H: (Where “H” is your USB drive letter)
Copy your Windows 7/Vista DVD contents to the USB flash drive.
Your USB drive is ready to boot and install Windows 7/Vista. Only thing you need to change the boot priority at the BIOS to USB from the HDD or CD ROM drive. I won’t explain it as it’s just the matter the changing the boot priority or enabling the USB boot option in the BIOS.
Note: If you are not able to boot after following this guide means you haven’t set the BIOS priority to USB.
