0xc0000428 Cant get past boot manager
I have windows 7 on my laptop and I attempted to update my OS to windows 8, which was mounted to a blank DVD, in hopes of wiping everything due to continuous blue screens of death and automatic restarts. It looked like the installation was going to go through until the system restarted and the windows Boot Manager screen came up. It says the digital signature for this file couldn't be verified. When I boot up windows 7, system ecovery tools appear. Startup repair doesn't do any good. I can't restore because of no restore points. How can I revert back to get my laptop working again? I don't have a windows 7 boot disc
