Hello I'm trying to setup Xpenology i did the whole google search and yahoo Plus YouTube. when installation is almost 2 minutes left i see on the screen of my system a Error message. Error: file '/boot/grub/i386-pc/norma.mod' not found. Entering resource mode... I'm not sure what this is I'm not a programmer my skills are in hardware. I'm learning as much as i can. When i search this i get different results online but I'm unsure what would be a fix. Can someone help me out please? Jc
