Every time your computer crashes, you need to reinstall the operating system. Rufus is a utility that helps format and create bootable USB flash drives, such as USB keys/pendrives, memory sticks, etc.
This tool useful for cases where:
- You need to create USB installation media from bootable ISOs (Windows, Linux, UEFI, etc.)
- You need to work on a system that doesn't have an OS installed
- You need to flash a BIOS or other firmware from DOS
- You want to run a low-level utility
To create a bootable USB flash drive you should download the OS that you want to install with ISO format, then plug your USB into the computer->select the os file->Click Start button
