A bootable USB lets you install an operating system on devices. You just have to plug in the USB and run the setup file from the boot screen. However, what if you need to install OS from an ISO file instead of the USB?

Sometimes, USB ports fail, or the USB device may encounter problems. Converting your bootable USB to an ISO can save you from these headaches. Plus, if you delete the original ISO after making the bootable USB, you will have to redownload it later.

Converting the bootable USB back to an ISO can help prevent such hassles. It’s easy to convert bootable USB to ISO on Windows; here are the two best ways to do it.
