I know this is a dejavu but let me please explain my problem.
When booting 13.04 installation media EFI mode get to a black screen with Grub version 2.00-l3ubuntu3 version appears after selecting "install" or "try Ubuntu", there appear error messages:
- failure reading sector ... from 'cd0'
- you need to load the kernel first

1. I have a Dell Vostro 3560 with Windows 8.
2. I have downloaded and burned ubuntu-13.04-desktop-amd64.iso. Hashes checked.
3. I've booted from the dvd with Secure Boot enabled.
4. The same happens when Secure Boot is disable.
5. When booting with Legacy BIOS, installation starts.

I tried Ubuntu without installing and looks OK. BUT, I did not follow the installation because in https://help.ubuntu.com/community/UEFI#Converting_Ubuntu_into_EFI_mode there appears "if the other systems (Windows Vista/7/8, GNU/Linux...) of your computer are installed in EFI mode, then you must install Ubuntu in EFI mode too.", which is the case in my computer.

I have read many similar questions and the corresponding answers from people in this forum, but till now I haven't found a solution.

Could someone help me on this subject?

Thanks in advance!
