The development of external USB storage devices has made it possible for computers to install an operating system (OS) even without a working CD drive or floppy disk drive. You can install Windows XP to a Dell OptiPlex SX260 from a USB flash drive. WinToFlash and FlashBoot can transfer the files on the OS CD to a USB device. You can then boot from the USB drive and install the OS to the OptiPlex SX260 just as you would from a CD-ROM.

Tips and warnings

  • You'll need to use another computer with a working CD or DVD drive to create the USB flash drive.
  • The above steps will format the files on the USB drive. Move any files on the drive to another storage device before proceeding. Don't move the files to the Dell hard drive, since the contents of the drive will be erased when the OS is installed.
