I have difficulty booting Ubuntu 14.04 LTS on Dell Inspiron 5558. The product originally come with Ubuntu (so I assume that it should run Ubuntu without any complication). I replaced the OEM HDD to SSD and I tried to install Ubuntu with USB. The installation process was going smoothly but I got a black screen after it reboot. I thought it was a problem in Dell UEFI configuration because I remembered that the original setting was set to legacy. I understand that (1) Ubuntu 14.04 LTS support UEFI boot, (2) UEFI have many advantages over legacy both performance and security so I'd prefer UEFI over legacy.
Please advice. Thank you in advance.
