Thanks for the warning. I was aware of that I have two disks (One HDD, and one 24 GB SSD) but most probably I'd forget that and format the 24 GB SSD (/dev/sdb).

So, my USB stick was /dev/sdc and I used dd command (btw, you made a mistake while giving the command, there shouldn't be a space in "of =/dev/sdN").

However, NOTHING CHANGED :( Same result. So there's nothing wrong with usb-creator, and what now? Do you think trying 13.10 would change the situation?

I want to clear something, when I try to boot Ubuntu installation via USB/DVD in SecureBoot, computer doesn't give any error output, it is able to show me the UEFI boot menu (Install Ubuntu, Try Ubuntu, Check Disk for Errors, etc.) but when I select any of them, it just waits in black screen without any error message.

So, I installed Ubuntu SecureBoot disabled, and then after enabling SecureBoot and trying to boot Ubuntu I received "Secure Boot Violation: Invalid signature detected. Check Secure Boot Policy in Setup".

So, while trying to install, computer doesn't give any error outputs, but it just doesn't continue.
