How do I reinstall Macintosh HD?

I was wiping my Mid-2012 MacBook Pro from all it's files and I accidentally deleted the Macintosh HD file. And now when I turn on my notebook it has a white screen with a grey flashing file icon with a question mark in the middle of the icon. HOW DO I REINSTALL MACINTOSH HD ??

Install OS X Using Internet Recovery
Be sure you backup your files to an external drive or second internal drive because the following procedure will remove everything from the hard drive.
Boot to the Internet Recovery HD:
Restart the computer and after the chime press and hold down the COMMAND-OPTION- R keys until a globe appears on the screen. Wait patiently - 15-20 minutes - until the Recovery main menu appears.
Partition and Format the hard drive:
Select Disk Utility from the main menu and click on the Continue button.
After DU loads select your newly installed hard drive (this is the entry with the mfgr.'s ID and size) from the left side list. Click on the Partition tab in the DU main window.
Under the Volume Scheme heading set the number of partitions from the drop down menu to one. Click on the Options button, set the partition scheme to GUID then click on the OK button. Set the format type to Mac OS Extended (Journaled.) Click on the Partition button and wait until the process has completed. Quit DU and return to the main menu.
Reinstall OS X: Select Reinstall OS X and click on the Install button. Be sure to select the correct drive to use if you have more than one.
Note: You will need an active Internet connection. I suggest using Ethernet if possible because it is three times faster than wireless.
This should restore the version of OS X originally pre-installed on the computer.

How can I reinstall Snow Leopard?

How can I reinstall Snow Leopard?

Jan,
You can use the Disk Utility "app" to partition your hard drive so that you can (clean) install Snow Leopard on the new partition. This leaves Mountain Lion intact on one partition. This worked great for me. I was becoming increasingly annoyed, seeing that Mountain Lion ***** due, as another poster said, to its "increasing iOSification".
With Disk Utility you can name the new partition "Macintosh HD 2". Be sure to use the exact same format as the original (Macintosh HD) partition. You can access all your files/apps on the old (ML) partition from the new (SL) partition, and vice versa.
However, know this:
I still have NOT found a way to transfer any my OS X Mail folders from Mountain Lion BACK TO Snow Leopard. Mountain Lion's Mail gives you the false impression you can export your Mail folders to Snow Leopard's Mail, but you cannot. From what I've read here, the newest version of OS X Mail is not compatible with earlier versions. This is a HUGE problem.
My short list (to date) of crappy Mountain Lion behavior; items marked with a double asterisk (**)represent the worst of Mountain Lion for me.
** No up/down arrows in scroll bar slider;
Expose` not as easy to navigate as in Snow Leopard;
Mail does not request passwords for either receive or send;
No "Save Draft" icon in Mail compose window;
"Save As" selection missing in most app menus;
No separate Search window in Safari (workaround: use Firefox or Opera);
** Can't export Mail from Mountain Lion into Snow Leopard if downgrading;
iWork 09 seems to have "circled the wagons" re compatibility with MS Office or LibreOffice (workaround: just use Libreoffice);
I truly regret "upgrading" to Apple's "Vista".

How do I reinstall if the original purchase was by the Mac dealer I bought from

How do I reinstall my software to fix problems? I tried to purchase on App store but it won't let me because it is already on my computer. Anyone have any pointers? The guy I bought my Mac from who is supposed to be a good dealer around here has been not helpful AT ALL!
thanks

It was pre-installed on your computer. When you first started up the computer you went through the Setup Assistant in which you set up your user account/name and password. I assume since you are here that you know your Apple ID and password.
If you need to do disk repairs and such:
Boot to the Recovery HD:
Restart the computer and after the chime press and hold down the COMMAND and R keys until the menu screen appears. Alternatively, restart the computer and after the chime press and hold down the OPTION key until the boot manager screen appears. Select the Recovery HD and click on the downward pointing arrow button.
When the Recovery Main Menu appears you will see what options are available such as running Disk Utility.
To Reinstall:

Alternatively, restart the computer and after the chime press and hold down the OPTION key until the boot manager screen appears. Select the Recovery HD and click on the downward pointing arrow button.
Repair the Hard Drive and Permissions: Upon startup select Disk Utility from the main menu. Repair the Hard Drive and Permissions as follows.
When the recovery menu appears select Disk Utility. After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list. In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive. If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported click on the Repair Permissions button. Wait until the operation completes, then quit DU and return to the main menu.
Reinstall Lion/Mountain Lion: Select Reinstall Lion/Mountain Lion and click on the Continue button.
Note: You will need an active Internet connection. I suggest using Ethernet if possible because it is three times faster than wireless.
Repair HDD and permissions:
Repair the Hard Drive and Permissions - Lion/Mountain Lion
Boot to the Recovery HD:
Restart the computer and after the chime press and hold down the COMMAND and R keys until the menu screen appears. Alternatively, restart the computer and after the chime press and hold down the OPTION key until the boot manager screen appears. Select the Recovery HD and click on the downward pointing arrow button.

My iTunes library is missing since upgrade Lion 7.2. I have it all backed up so that's not the issue. How can I reinstall it with all my hundreds of playlists intact or do I have to recreate each one upon reinstalling the backup copy? Thank you for help

Almost my iTunes library is missing since upgrade Lion 7.2. (the last 2.5 weeks worth of added music has transferred post-upgrade, none of whcih was bought from iTunes)
I have it all backed up so that's not the issue. How can I reinstall it with all my hundreds of playlists intact or do I have to recreate each playlist upon reinstalling the backup copy? This would save a HUGE amount of time and efforts. Thank you for your help!

hi Limnos,
I do not mean the entire ITunes folder but, rather, the contents of the ITunes folder prior to September 29th. (90% of the media is missing, along with all playlists) The media that remains says it was added on 9/29 although I know most of it was added many months or even years earlier. There are no playlists listed at all, before or after 9/29. (I know for certain that I added non-iTunes purchased songs on 10/6 although I had not created playlists for them)
I have my iTunes folder backed up on both an external drive as well as Time Machine.
I run iTunes off of an ITunes folder on my computer rather than from the external, if that's what you mean about how I have it set up.
Is it OK to drag the entire iTunes folder from the external drive onto my laptop's drive and see if that fixes it?
Thank you for your help!
Deb

How to recreate iTunes Library
No content shows up in iTunes after updating

I attempted to install an update to my iTunes and got a "C Runtime Error" message. Now when I attempt to open iTunes I get a pop up that says to reinstall iTunes. But I can't open iTunes to reinstall it. How can I reinstall iTunes?

I received notification of ANOTHER iTunes update being available, so I attempted to install the update on my Toshiba Satellite laptop running Windows Vista. During the update process, two pop-up announced that I had a "Microsoft Visual C++ Runtime Library" Runtime Error, R6034 and another pop-up that states "iTunes" iTunes was not installed correctly. Please reinstall iTunes. However, I cannot open iTunes. I get the same pop-up telling me to reinstall iTunes.
I had many songs in my iTunes library that came from sources other than iTunes, mostly my own CDs. Plus, I have nearly $100 credit remaining in the iTunes store. I'm converned I will lose the songs and store credit if I reinstall iTunes. So my questions are:
1. How can I reinstall iTunes?
2. If I reinstall it, will I lose my store credit and non-iTunes songs?
Thanks,
Jim

Nothing should be lost... However... it is both Prudent and Recommended that a backup should have been created and maintained.

You are allowed to have two machines with activated installations, so if you only had one installation, you still have the option to install on a second without doing anything further than that. If you originally downloaded the purchase thru Adobe then you might find a download link available in your Adobe account online. You can also download thru the following page if you can find your version:
Download and Installation Help -
https://helpx.adobe.com/download-install.html
You can have the first installation deactivated to free up the activation and have it available for another machine again as well. YOu need to contact Adobe Support thru chat for that. For the link below click the Still Need Help? option in the blue area at the bottom and choose the chat option...
