Hey guys. i'm currently using bootcamp right now but I am unable to boot into the Mac OS of my hard drive. I have a 2010 Macbook Pro using a Momentus XT Hybrid SSD, which was installed in it 5 years ago. I hope it's not a symptom of a hard drive failure. my bootcamp side works as expected. I am seeking help to be able to boot on El Capitan again. When pressing Alt to switch into bootcamp, the Macintosh HD drive name has changed to EFI boot. when i try to boot on Mac, the progress bar always stops at around 70%, and then it shuts off if it hangs around there for too long. I also tried holding command+R during boot to access recovery mode/disk utility, and it can't find my Macintosh HD OS. only my bootcamp. Please help! Thanks!
