MacBook Pro Stuck on Apple Logo
Hello,
I have a MacBook Pro A1286 on El Capitan.
For some reason it has started "boot looping" - IE it will get 3/4 of the way across the loading bar, then loop round and start again.
I don't appear to have a recovery partition of any description built into the hard drive.
I've done the PRAM and SMC reset to no avail.
I'm trying to boot from a Snow Lepoard disc that came with the Mac - I hold alt, and it detects the disc, so I select it.
From there, it simply gets stuck on the apple logo, and doesn't do anything.
Any advice?
Thanks in advance.
