El Capitan Cannot start after upgrade

Dear all,


After my mac downloaded El Capitan and restarted itself, the loading page appeared and the loading line below the apple sign started to install, BUT stopped at about 90%, for hours! I left it go to bed. I woke and found same page still loading at 90%! So I force restarted the computer, a log in page appeared, once I type my log in details the loading line started load but stops at half way Now! Anyone knows what to do Please? I need at least to go back to previous OS X system so I won't lose my files.


look foward to hearing from your suggestions! many thanks!

MacBook Pro (Retina, 15-inch, Late 2013), OS X Yosemite (10.10.5)

It took me an hour and 6 restarts (after forced quit) for the ****** thing to finally load and show my files. I'm very very tempted not to do further upgrades until they've been around for about 6 months or so and had the bugs worked out. First try got white screen. Second try, Apple icon with partial load; third try log in and then spinning beach ball; fourth try log in with white window and spinning beach ball; fifth try Apple icon with partial load; sixth try it finally all worked and apparently all my files are there. Geez, if I wanted an experience like updating a Microsoft OS, I would buy a PC.
