Error Loading OS

[Amazin Caucasian]

Hello everyone, It has been a while since i have last posted...a month. For those of you who folowed my last thread and helped me fix my PC I greatly thank you, especialy Pam123. I could not fix it myself after hours on the fone with asus and Microsoft, so in order to quickyl fix it i brought it into a PC repair shop down the street from me. I got it back 3 days later and my dad paid willingly happy it was fixed and now it is back in my room, and i am currently copying all files back onto my drive as i type now. Now i have a new problem, well it isnt so new. Before i had my issue everytime i booted i had an error message saying Error Loading OS right after it lists the PCI devices. In order to boot all i had to do was go to the Boot menu and select the Raptor, although small process it is a nuisance and I would like to fix it. Any ideas??
