Anyone out there that is beta testing Windows XP pro 64-bit. I have an excellent problem. It turns out about the forth or fifth reboot 64-bit seems to want to tell me that ntoskrnl.exe is not in the Windows/System 32 directory and to reinstall it. I have a dual boot machine so I went to check it out and it turns out that ntoskrnl.exe is there. Anyone have a fix other than going into recovery console or reinstalling. Also, is there a way to prevent this from happening again.
