Usually we can boot up something like : Widows , BartPe… by using the CD/DVD, But you can use this program to make or Convert it to boot from the Flash Drive.
FlashBoot is a tool that makes USB disks bootable. It was specially designed to work with USB Flash devices.
It is used to reformat flash disk (that’s optional) and transfer system files to it. You have many options for your choice:
* convert BartPE bootable CD-ROM to bootable USB disk
* transfer DOS kernel only (you may get the files from installed Windows 9x, from Windows 9x setup folder, or use built-in FreeDOS)
* convert floppy disk to USB Flash disk (a diskette or an image file may be used)
* convert a bootable CD-ROM to USB Flash disk (again images are supported). There are some technical difficulties with supporting any type of CD-ROM here, see details below. But there should be no troubles with the most real cases. You may convert Knoppix and EBCD, for instance.
* create Windows NT/2000/XP password recovery disk
* create disk with NT/2000/XP bootloader. It would be useful when you have mistakenly configured it, and boot.ini file was left on unreachable disk (NTFS).
* duplicate USB flash disk. Just creates a copy of existing disk USB flash disk, different sizes of source and destination medias are OK.
