Hi, first time here. A couple of days ago, my pc didn't shut down normally, because some windows 7 patches were installing, just normal stuff. So, I turned off the monitor and leaved the room. Today, when I start the PC, I get an error saying: "Error loading operating system". So I thought, fine, Windows updates screwed up my OS, lets make a quick repair so everything goes back to normal. Nope. For some reason I cant start from my Windows DVD, even having the proper boot order in the BIOS. It just doesn't read my DVD at all. A year ago I installed this PC without problems, but now it refuses to boot from the DVD, which makes my PC unusable because the OS is broken. Any ideas?
