My Macbook pro MD101HN/A is not booting its shows apple logo and then its getting off

MD101HN looks to be a MacBook Pro (13-inch, Mid 2012) model. Boot to Safe Mode and see if you get further through the startup. If that works, shut down and reboot normally, and see if the MacBook Pro now works. If not and if the tools will start, try running hardware diagnostics. You might also try resetting the SMC and the PRAM. See if an external bootable disk can be booted, if you have another Mac and can create one of those. Failing this, you're headed to your local Apple store or your preferred hardware support vendor, or doing some reading on self-maintenance for whatever might be wrong here.

Thanks MrHoffman but I tried this but it's not working it's says some error in macintosh HD

Please consider describing what is and is not working in a little more detail. It's clear that one or more of the suggestions failed, but did any of those work? If the hard disk has failed, some — such as booting from an external disk — should still work.

Also please post what the specific error message was, as there are many different errors that can arise — anything from a volume corruption to a failed hard disk, to a problem with the MacBook Pro electronics.

Alternatively, see if the local Apple Store or a local repair shop or reseller will run some diagnostics for you.

If you get the error code in Hardware DIagnostics, there would be an error code . Post it. If you get it in Safe Mode, report here the exact wording. If you can boot to recovery do so and run disk utilities to check or repair you hard drive And permissions. If you get an error there ,post it. If it tells you hard drive cannot be repaired. You would have to use recovery to reinstall the operating system. Do you have a backup of your hard drive?
