Just installed OS X updates and can no longer boot into Bootcamp
Just installed the latest updates for OS X Yosemite and now I can't boot to my Bootcamp partition. It doesn't show up in Startup Disks and it's not an option when booting while holding Option. The partition still shows up in Disk Utility but it no longer says BOOTCAMP, it now says disk04s. Is this fixable? I just wrote some data to that partition last night that I really don't want to lose and it hasn't yet been backed up. Thank you.
