So im using Macbook pro mid 2009 Maverick. I have only one HDD at /dev/disk0 Few days ago i installed Linux Mint running parallel with my Maverick.

In order to be able to boot from my USB flash storage which contained Linux Mint I installed rEFI ( I dont know i couldnt boot by native way - pressing alt key when restarting to open the boot preference screen ).

The Linux Mint installer installed GRUB on my MBR .

Now I want to install Kali linux to replace linux mint. However i dont see the boot from USB option in rEFI as I did with linux mint.

I guessed that my MBR is messed up now i want to remove GRUB. I searched google and found this solution :

Code:
sudo fdisk -u /dev/disk0

and it returned :

Code:
fdisk: could not open MBR file /usr/standalone/i386/boot0: No such file or directory

So my question is : Did the Grub hinder me to boot from USB ? And how can I boot from the USB with Kali Linux as i had installed with Linux mint ? How can i remove the GRUB by the way ?

All help welcome. Thanks
