BootCamp drive not showing up in startup disk.
Just today i noticed that my bootcamp drive is not showing in startup disk in system preference. I am using 10.11 El Capitan. However, I have been able to boot to both of the OS's pressing the 'option' key. And also disk utility is not showing the bootcamp partition. But in finder, it shows the partition. When I try the disk utility in recovery mode, there it shows the bootcamp partition. But not in OS X.
And at last, when i try ' get info' guess what: it shows Last Opened: January 1 1970, at 5:30 am. which is never true.
Is this OS X issue, How do I fix it?
MacBook Pro, OS X El Capitan (10.11)
