But USB-attached storage devices holding gigabytes of data are everywhere. Now optical drives are disappearing, too. Years ago, bootable disks were floppies then came CDs. If the patient's condition is more serious, you might even need a bootable disk to recover your OS, disk, or entire system from the full backup you also made (you did, right?). When your PC won't start, the bootable disk you created in a rare moment of foresight will often let you boot into Safe Mode or System Recovery, where you can fix the problem and reboot normally.
Rufus Portable creates a bootable USB drive that can help you recover your system when very bad things happen to it.
