I am using windows, I have downloaded ISO of Vector Linux 7.0 (VL7.0-STD-GOLD.iso). I don't have a CD Rom, How can I create a bootable USB of this Linux to install it on my system.
Unetbootin don't support vector linux.
The working solution is : LinuxLive USB Creator 2.8
Note: Universal-USB-Installer does NOT support VectorLinux
try the linux USB installer from PenDriveLinux. its pritty easy to use and works with any downloaded Linux Live ISO.
