I have Windows 8.1 and Ubuntu installed. I had ran boot-repair since the os selection menu wasn't showing.

A few days ago, I downloaded the latest version of Kali Linux. I used PowerISO to copy all the files to a 16GB usb stick(USB 3.0). I rebooted. In the menu when booting, I moved 'USB HDD' to the top of the list and saved.

This is exactly what I did when installing Ubuntu. With my USB stick inserted into the usb port, I hit the power button of my laptop... the purple grub menu showed up.

I rebooted few times, but it still showed the grub menu. I booted into Ubuntu and ran a md5 checksum. Everything is ok.

Any help?

  • @JodkaLemon I did read the documentation but I was on Windows so I don't want to install additional software(I have PowerISO)

Just copying the files is not enough because you will miss the bootloader.

You should dd the image to the usb stick:

dd if=kali.iso of=/dev/sdX bs=4M; sync

to start it.

Be aware, that this will delete all data on the stick and the partition scheme will not be optimal.


Since you're on Ubuntu, you can also use the Startup Disk Creator. It's a bit easier to use than dd, IMHO.
