uninstall all of kde

What was the command that you entered? It seems that you have mistyped it.

The command att the link,@how to "remove kubuntu"
or else:

that was the command :D

You must have mistyped the command, because the output quotes "E: Unable to locate package vassilios", so you must have requested to remove a (nonexisting) package vassilios!

I recommend you try again.

i've deleted all the packages listed as an error "unable to locate ....." from the command line then "enter"

after that I reboot my system, as a result:

ANY HELP PLZ?

The output indicates that there is a problem with logical volume management on your system. Either the required drivers are missing, or the LVM definitions are wrong, or the partitions got damaged.

I assume that together with the kde-only packages you have removed also some essential packages that would be needed in any case. Or maybe you have done some other modification with you hard disk, which now is causing the problem.

I assume the best approach is a complete new installation of Ubuntu.

I hope you have followed the advice in http://www.psychocats.net/ubuntu/pureubuntu
"I am not responsible for any damage you do to your *buntu installation. If you're worried about breaking anything, do a full back up of your *buntu installation." and created a backup which you can restore.

Booting into a live system might reveal some more information what the real problem with your hard disk is, but I doubt if that would help much.

Can't access to recovery mode neither boot on live USB
and always "Kernel panic" in every reboot

In your previous message you wrote that you end up at a grub prompt, but now you write about kernel panic?
Please describe what actions you try and what the result is.

after booting on live USB, choose install ubuntu, kernel panic:
https://scontent-cdg2-1.xx.fbcdn.net/hphotos-xpa1/v/t1.0-9/12088348_121840668172051_5558456868492593240_n.jpg?oh=051f2f154d3d2d2d27d4ad8f89bbaa1c&oe=5693A08A

At what moment do you see this problem? Have there already some questions been asked?
Do you get the same kernel panic abort also when you select "Try Ubuntu without installing"?
Are you sure that the live USB is without errors, have you already used it elsewhere, and/or have you done an MD5 check on the .iso file before creating the USB stick?

yes "Try ubuntu without install" or "INstall ubuntu" same problem, same kernel panic
and i'm sure of the live USB without errors

I have re-download .iso and re-boot again and everything is fine
Thanks alot :)
