I've had no end of problems while installing Ubuntu. I'll go through all the situations I've faced- -Installed via USB flash drive due to the lack of a CD drive in new PC build -Booted up through the USB drive just fine and got into Ubuntu while running off USB Decided to mess with it for a while just off the thumb drive and try to run some benchmarks compatible with Linux such as Unigine's few and such. These .run files would come up in "gedit" (whatever the hell that is) and just tell me it cant run. "gedit has not been able to detect the character coding". Some guide said its possible I must active root priveleges so i opened console and attempted to run root, which told me to install Sudo, which gave me a message saying sudo couldn't be installed because it wasn't found. After lack of success decided to install. "Hey maybe it just can't run it because it isn't installed" -Went through installation process to find that none of my HDDs would show up -Ended up having to take 2 of my Seagate drives out of Raid0 to have them appear, and my Samsung F3 won't show up at all while plugged into my sata6gbs -Went through process again and successfully installed onto Seagate -It forced restart, and prompted removal of installation media. I removed the USB -Restarted.... and nothing. Can't boot from HDD Now when I boot of the USB I can go into System and find the 160gb Seagate with Ubuntu clearly installed on it, but still can't boot off of it. I seriously can't understand how such a shotty OS with so many compatibility issues is used by anyone on a daily basis. Anyways, if anyone might divulge as to what I am doing wrong I would greatly appreciate it.
