Burn ISO image file directly to the USB drives. Bootable USB is more convenient than bootable CD or DVD, because USB can be used more than CD or DVD and we can use it and re-use it without any problem. Operating systems, live rescue disks, bootable media and many software are available in ISO format. We can not use ISO directly. We have to burn it on disks or extract it on USB drives to make it usable. You can easily take an ISO file and create a bootable USB disk from it by following tips below.
Bootable rescue USB drives are handy when:
- You need to create USB installation media from bootable ISOs (Windows, Linux, UEFI).
- You need to work on a PC that doesn’t have an operating system installed.
- You need to work on a PC that has a damaged operating system.
- You need to flash a BIOS or other firmware from DOS.
- You want to run a low-level utility.
Tip: When you are creating a bootable USB disk, we suggest you choose the FAT32 file system.
RuFus is a little utility to make bootable USB drives. It can format the USB drive for NTFS, FAT32, UDF and exFat file systems. You can assign new volume label for USB drive. Partition schemes include: MBR partition scheme for BIOS or UEFI computers, MBR partition scheme for UEFI computers and GPT partition scheme for UEFI computers. You can determine cluster size. It can check device for bad blocks. You can create bootable disk by using ISO image or DD image.
While creating bootable USB by using Rufus, select ‘MBR partition scheme for BIOS or UEFI computers’ and select ISO file and click start. All data from USB will be erased and from selected ISO file, it will create a bootable USB drive. Whatever was in that ISO image file will be able to boot and if you plug that USB in the computer and change computer’s BIOS settings to boot it from USB drive, you computer will boot from that USB drive. This is very useful in creating live rescue USB disks. Rufus is portable and multi-language utility.
ISO to USB
ISO to USB supports NTFS, FAT, exFAT, FAT32 file systems and it can also create bootable USB drive from an ISO file. Browse for ISO file, select file system type, check bootable option and burn it.
Another software to create bootable USB drive (specially for Linux operating system) from ISO file is ‘Universal USB Installer‘.
We have used ‘Rufus’ and ‘ISO to USB’ and both are great.
