windows won't bootup

[DarKnoob01]

I recently upgraded my motherboard from a gigabyte h77 to an Asus iv gene z and when I try to boot windows 7 it goes to the startup menu when I press normal bootup it just loops back to the menu and when I choose startup repair I get error 0x0 and nothing happens any help would be appreciated!

try with the windows 7 DVD or USB fire it up and select repair windows this will fix the system, and probably will repair the corrupted files.

Try booting into safemode or a fresh install, garbeth's suggestion should work though

Try windows repair CD and open cmd and type bootrec /fixboot and it should boot up.
