I was just recently trying to install Xubuntu onto my desktop computer but it gave me a message telling me to insert another disc and I had no clue what to do so I restarted. when I restarted I received a message that said "Operationg System not found" and the cd was in the cd drive and it just wasnt booting. I tried to get into bios but it just won't work. Everytime I hit a key I get a grindy beep from my computer and another line of "Operating System not found". I restarted the computer and nothing seemed to work. Please Help!!
