ISO to USB is a free and small software that can burn the ISO image file directly to the USB drives, these USB drives include USB flash drives, memory sticks and other USB storage devices, it also supports to create a bootable USB disk with Windows operating systems. So, you can make your own bootable pen drive directly from ISO images without mounting them on a virtual drive or involve yourself in any system copy process.
The application is very easy to use and creates a USB bootable pen drive with one click. You can use this application to not only create bootable USB pen drive but even use it to burn any type of ISO file to USB. The program’s interface is very simple, you only need select the ISO file you want to burn and the target USB drive, then click “Burn” button, an USB disk that includes all ISO image data will be created. They do not have any complicated settings, it’s just way too easy to use.
Currently, this software supports only Windows bootable disk and you can use USB disk with FAT, FAT32, exFAT or NTFS file system. (When you are making a bootable USB disk, I suggest you to choose the FAT32 file system.) This program was tested to work with WinXP, Win7 PE and WinXP PE.
