I just made a raid array from two western digital 1tb caviars and everything went fine when I installed the OS until it finally got to were I was suppose to login. So I logged in with my account and I was at the metro screen for two seconds then all of a sudden my computer restarted itself! I didn't think anything of it at first until I got an error saying "cannot find OS, remove all other drives that do not have OS". I put the CD key in to try and reinstall Win 8 to see if that would fix it, but it turns out it boots up fine with the CD in the disk tray. What the heck? I don't want to leave the installation disc in my tray all the time. Can you not install you OS on a raid array? Any help would be appreciated!
