Hello, I had normally run kubuntu 12.04.1 (x64) on my sony vaio laptop before, few days ago, installed updates for EFI. Next boot I got GRUB menu but when try to start kubuntu I saw on the screen error: symbol not found: `grub_efi_secure_boot'. On recovery mode same.
I tried boot-repair it did not help, then tried to install 12.10 bad results - no menu at all, than I downloaded 12.04.1 and installed it again and now have menu but the same error when try to start kubuntu.
Here is my last boot-repair report http://paste.ubuntu.com/1503274/
Can somebody help me.
