proproblem Unetbootin

[mercier2]

Hi ,

I have a problem with Unetbootin.
I wanted to change Ubuntu with Kali so I had my ISO on an external hard disk.
I used Unetbootin for that, followed the instructions which rebooted it.

But now I can't launched Kali. I have 5 solutions :
1-Unetbootin
2-Back
3- live USB Encrypted persistence
4-Install with speech synthesis memory 5-diagnostic tool (memtest86+)
What is displayed when I click on it:
1-
error: disk 'HD0,2' not found
I have to turn off the computer because I can't go back
2- Lot of code like this:

error: secure boot forbids loading module from (HD1,gpt2)/grub/X86_64-ego/adds.MOD
And a t the end:

Unknown file system
3-lot of coding like this

error: secure boot forbids loading module from (HD1,gpt2)/grub/X86_64-ego/adds.mod
And at the end

error : unknown file system.
Unaligned pointer 0X9594e558
Aborted. Press any key to exit.
4-
error : file '/ubnkern' not found.
Unaligned pointer 0X7e465b8
Aborted. Press any key to exit.
5- lot of coding like this

error: secure boot forbids loading module from (HD1,gpt2)/grub/X86_64-ego/affs.mod
And at the end

error : unknown file system.
Unaligned pointer 0Xc7c9c558
Aborted. Press any key to exit.

And I can't even go back to Ubuntu so I'm blocked here.
Sometimes it display the boot menu where I can see that Ubuntu is still there but when I select it, it's coming back to the first menu.

I hope I'm clear.

Thank you for your help.

Have a nice day.
