The mkbootdisk command is a Linux command that is used to create a bootable floppy disk or USB drive for the current system. This command is useful when you need to create a bootable disk for your Linux system in case of an emergency.
Overview
The syntax for the mkbootdisk command is as follows:
mkbootdisk [options] [kernel-version]
The kernel-version parameter is optional and specifies the version of the kernel to use when creating the boot disk. If this parameter is not specified, the command uses the currently running kernel.
