Can't boot into persistent mode live USB only forensic.

[perception]

Good day everyone.
I would like to have a live USB that can run on all 64bit pc's with persistence. At first I tried installing it to a USB like it was a reguar HD but that was SLOW as ****. Now I made a live USB with persistence using this http://docs.kali.org/installation/ka...ve-usb-install tutorial.

But whenever I try to boot into persistent mode it starts up but then it gives a black screen (sometimes I see a white pixel flashing). Not even an error message..

I have an i7 and a GeForce GT 750M, does kali maybe have a problem with nvidia cards. (I had a problem like this on backbox too and it could be fixed with "nomodeset" command). Although it's weird that the forensic mode does work..

If anybody has any ideas on how to fix this problem.
I would love to hear them.

Thanks

Hello everyone I forgot about this thread but fixed the problem. And I though people might have the same problem. It was because of the dreaded uNetbootin. So people don't use Unetbootin it messes up your persistence, grub bootloader.
