Hello, my iMac pc that has windows 7 stopped working, it keeps running the automated start repair and keep restarting after it tells me it has a problem, and when it says it fixed it, it just keeps going in a loop with the start repair, and i can't seem to access any way to boot the pc cuz it keeps telling me that it can't find the OS Loader after i had a powersurge, i need some help, i even tried making a disk partition of Windows 7 install to a USB and when i plug it in, it wont give me an option to boot from it and i even tried the Windows 7 Install CD and it still doesn't work, cause when i start the pc it shows a gray screen, till it says loading windows files, then it goes right to the automated start repair thing, and its driving me nuts! if someone could help me i would be appreciated!
