Because Kali Linux is based on GRUB2, you should use GRUB2. Next, you must select the bootloader for your Linux distribution. If you want to add a new entry to Linux or BSD, go to the “Linux/BSD” tab and select Add New Entry. If necessary, press any keyboard shortcut for a “boot order menu” (depending on which manufacturer you are using) or boot into BIOS/UEFI and change the boot order to point to the installation medium first. If you want to begin the resizing process, first ensure that your Kali Linux installation medium and power are both turned on. Once the process is complete, you will need to restart your computer and boot from the USB drive. The Rufus program will now start creating the bootable Kali Linux USB drive. Once you have selected the ISO file, you will need to make sure that the “Boot Selection” option is set to “Disk or ISO image” and then click on the “Start” button. After that, you will need to click on the “…” button and select the Kali Linux ISO file that you have downloaded. Once the program is open, you will need to select the “Create a bootable disk using:” option and then select the “ISO Image” option. Once you have downloaded the program, you will need to unzip the file and then run the “Rufus.exe” file. In order to install Rufus in Kali Linux, you will first need to download the Rufus program from the official website.
