Problem Booting Kali via USB on Samsung Chromebook 3

[L3g3nd4ry]

Hi guys!

Unfortunately, I can't get my Chromebook dual booting into Kali via my flash drive.

Here's what I've done so far:

• I have installed the correct ARM image using Win32 Disk Imager.
• I have put my Chromebook into developer mode.
• I have repaired my Flash Drive with the command

  sudo cgpt repair /dev/sda

• I have enabled cross system booting with the command

  sudo crossystem dev_boot_usb=1

Now here's the problem: When I try to modify my partition order with

sudo cgpt add -i 1 -T 5 -P 5 -l KERN-A /dev/sda

and

sudo cgpt add -i 2 -T 5 -P 10 -l KERN-B /dev/sda

I get an error saying

ERROR: cgpt add: -t, -b, and -s options are required for new partitions

Any ideas what I'm doing wrong?

I'll provide my flash drive's current GPT table for reference:

start     size part contents
0         1    PMBR
1         1    Pri  GPT header
2         32   Pri  GPT table
15124959  32   Sec  GPT table
15124991  1    Sec  GPT header

Also, if it helps, I'm following these two guides:

• http://docs.kali.org/armel-armhf/ins...ung-chromebook
• http://mihirsingh.com/kali-on-chromebook/

Thanks!

NOTE: I'm completely new to Linux, and so this has proved to be a challenge; Sorry if I'm doing something obviously wrong...

What does "cgpt show /dev/sda" look like.

I don't think this will affect anything, but it's an 8 GB flash drive.
