Rocky 9.x Ventoy is better than using this option

To create live bootable USB using iso in CentOS 7.x use:

1. Install required packages

   yum -y install unetbootin liveusb-creator

2. Start "Fedora live usb creator" ('liveusb-creator') GUI program
3. Click on button under download fedora label and select desired ISO. Name of appropriate ISO selected would be displayed on log screen.
4. *Validate* that correct device eg /dev/sdb1 is selected and not internal disks.
5. Choose "Overwrite device" dd method after *ensuring* no useful data on pen drive.
6. Click "Create Live USB" twice to confirm about removing existing data and proceeding.

Live CD tools

If the above fails to recognize USB device then try:

1. yum -y install livecd-tools
2. Then create liveusb using following command:

   livecd-iso-to-disk --format --reset-mbr --efi <iso-file> <device-name>

3. After this run "Fedora live usb creator" and it should show the USB device. Now use "Fedora live usb creator" to create proper bootable device with "dd" destructive overwrite option.
