Dropped my Macbook Pro

Hold down the Option key while you start up and see if there is any drive that has Recovery in its name. If there is, select that and it will boot up some Utilities including Disk Utility that can be used to check/repair your hard drive.

If nothing comes up you need an older DVD for a MacBook Pro pre-2011, or start up again and hold Command-Option-R for a MacBook Pro newer than 2011.

BOOTing from a Hard drive is much more difficult than reading data files from a hard drive. Mac OS X itself represents over 350,000 files on your hard drive, while the files you created and cannot reproduce through a fresh Install probably number only in the hundreds.

If your drive will not perk up after a Disk Utility (Repair Disk [directory]) you may indeed need a new drive. Don't be in a hurry to erase the old drive -- you may be able to salvage files off it later. If you have Trusted Backup, you have many more options for restoring your old files.

If you were able to run "regular" Recovery (as opposed to Internet recovery) there is still a working Recovery/Utilities partition on your old drive. When you get a new drive, get an enclosure or adapter to run it as an External, and you can use the old Recovery to Install the new Mac OS X on the new drive.

Hi. Did you run disk utilities in recovery and if told you the dive was not repairable? If the drive is not physically damaged you might be able to erase the indented drive in disk utilities an go back to recovery and select the reinstall option. I would do this using a ethernet connection. If it will not reinstall and the drive is damaged, then you will need to replace it. Then reinstall the operating system. Doing this depend on what year and model Macbook Pro you have.

The reason I suggest a new drive, stored temporarily in an external enclosure, is that is separates the Installation and running issues (which are perfectly doable on a Drive in an External enclosure) from the drive-swap surgery issues.

If you had been able to access the on-disk Recovery, it is often easier to do the Install from there onto the new drive as an external drive. But this does not apply in your case because your "regular" on-disk Recovery was not readable. Luckily, your Mac is new enough to use Internet Recovery. Those from pre-2011 can not do Internet Recovery.

Grant Thats not entirely true about pre 2011. it depends on the year and model. I have a 2010 early Macbook running Yosemite and I have internet recovery. Some 2008 models with Maverick or Yosemite can use internet recovery.

Some computers that did not come with OS X Lion or later installed can use the OS X Internet Recovery feature after applying a firmware update:

• MacBook Pro (13-inch, Early 2011)
• MacBook Pro (15-inch, Early 2011)
• MacBook Pro (17-inch, Early 2011)
• iMac (21.5-inch, Mid 2011)
• iMac (27-inch, Mid 2011)
• MacBook (13-inch, Mid 2010)
• MacBook Pro (13-inch, Mid 2010)
• Mac mini (Mid 2010)
• MacBook Pro (15-inch and 17-inch, Mid 2010)
• iMac (21.5-inch and 27-inch, Mid 2010)
• MacBook Air (11-inch and 13-inch, Late 2010)

from memory, I can remember computers from around 2011 could include this feature, and older ones could not.

Did you remove the hard drive from the Macbook Pro? Or are you talking about the screws on the Macbook? Do not take the hard drive apart. It cannot be fixed in that way. Do you have an external hard drive. If you do you can install the operating system on it by using recovery as long as you leave the one in the Macbook pro ,in the Macbook Pro. Reinstalling the operating system through internet recovery, may or may not work. There is an arm inside the hard drive, not unlike the arm on a record player. If it scratched the disk when dropped you might not be able to erase and reinstall.

All 2.5" drives are strictly rectangular, with nothing protruding beyond that rectangular solid. Anything that sticks out beyond that is added for ease of mounting.

On some MacBooks, there are screws added to the drive that stick out on the sides. These may be used as mounting posts. On some drives, electrically-insulating tape is applied to the drive to keep from shorting out things on the drive's face against the metal inside the MacBook.

Screws that hold the drive together often have heads with unusual shapes, such as star-heads. These are used to keep you from dis-assembling the drive by mistake.

He is a link to check your support. I can only get to this page as it tells me my version of safari is not supported. You will need to click on check coverage down on the bottom. I did this once on an Imac my daughter had. You will need the serial number for your Macbook Pro. https://www.apple.com/support/applecare/ If you bring it in to the genius bar ,they will look it up using the serial number also.
