What is the best way to restore a Mac without a recovery partition?

If the problem is serious, you may need to reinstall your entire Mac operating system using the recovery partition. But how do you recover a Mac that is missing a recovery partition?

It's possible to restore a Mac without a recovery partition, but it can be difficult (especially on older Macs). You have two approaches:

Use Internet Recovery to reinstall OS X on a Mac with a missing recovery partition.
Create an OS X installation disk from your old USB Thumb Drive and reinstall OS X.

We'll cover both of these options in this feature - but first, let's quickly explain what a recovery partition is.

How to Recover a Mac Without a Recovery Partition: What is the OS X Recovery Partition? (What are partitions anyway?)

Most people don't really think of hard drives in terms of partitions (and volumes). They simply see the entire disk as one.

The hard part is usually one volume, but then it is broken up into several areas called "partitions". Think of your hard drive as a house, and the partitions as different rooms.

You're used to seeing only one room in the house, which has its own desktop, folders and applications. But there are four partitions, and one is used in extreme cases where you might want to completely reinstall OS X. Even if you completely wipe OS X and start again from scratch, the recovery partition will be there to go in and reinstall OS X.

This is a problem if the recovery partition is missing. After all, how are you going to reinstall OS X from scratch? This happens: If you put a new hard drive on your Mac or accidentally destroyed the recovery partition by installing Windows, Linux, or another OS on your Mac, you may not have a recovery partition to work with.

How to Recover a Mac Without a Recovery Partition: How to Check If Your Recovery Partition Is Working

First you should check that your Mac definitely does not have a working recovery partition. It used to be that pressing the Option key in OS X would create boot disks (including the recovery partition). But now it only shows OS X system drives (typically just your primary hard drive).

Here's how to boot into Recovery Drive:

Turn off your Mac. (Apple menu > Shut Down.)
Hold down the Command and R keys at the same time and press the Power button.
Continue holding Command and R until the Apple logo appears on the screen. Release the keys and wait until your Mac shuts down. (This will take longer than usual.)
You should be faced with a screen that says OS X Utilities. This is the recovery partition. If you have this, stop worrying. You're good to go.

If your Mac boots into OS X, or if you're faced with a completely blank screen, then you don't have a recovery partition. If your Mac boots into OS X, you can also check Terminal to see if there is a recovery partition:

Open terminal.
enter Scout list.

You should see a list of all volumes and partitions on your computer. The first drive (/dev/disk0) should have a partition (usually listed as "3" with Apple_Boot Recovery HD after it). Try again using the Command-R process. Before you move on to reinstalling OS X, try a few of these tips:

Reset your PRAM. Shut down your Mac and hold Command-Option-PR while booting. Wait for the chimes and let go.
Check your keyboard (especially if it's a Bluetooth keyboard). If possible, use a wired keyboard.

Okay, so either your recovery partition is missing or not working and you've tried everything. So, it's time to look at reinstalling OS X. You should first take the time to back up OS X if you can use Time Machine. This will allow you to recover all your files, folders and applications after reinstalling OS X.

How to Recover a Mac Without a Recovery Partition: Use Internet Recovery to Reinstall OS X

If you don't have a recovery partition on your Mac, you'll need to reinstall OS X. Even if OS X works, you should probably consider reinstalling because a missing recovery partition isn't a good sign. But mostly you will face this problem when OS X is not working and you are not able to restore it in the normal way.

The first approach is to use the Internet Recovery feature. New Macs can boot directly from an Internet connection, even without using a recovery drive. Here's how to use OS X Internet Recovery:

Turn off your Mac.
Hold Command-Option-R and press the Power button.
Hold down the keys until a spinning globe and the message “Starting Internet Recovery” appears. It can take some time ".
The message will be replaced with a progress bar. Wait for it to fill out.
Wait for OS X Utilities to appear.
Click "Reinstall OS X" and follow the installation procedure.

There are problems with Internet Recovery. It only works with networks that use WEP and WPA security. This is most home Wi-Fi networks, but if you are on a proxy or PPPoE network then you will have problems. In these cases, it's usually better to find another network rather than create a USB Recovery Stick (our next step). If you have Internet Recovery, use it to reinstall OS X if possible.

How to Recover a Mac Without a Recovery Partition: Create a Bootable OS X Installer from a USB Drive

If you don't have internet recovery, you're left with the final option. This is done to create a bootable installer from a USB drive (at least 8GB in size). Note that this completely erases the USB drive, so be careful to delete all files from it first.

There are two ways to create a USB flash drive installer. One is to use the terminal, the second is to use the DiskMaker X application. Here is the terminal approach.

Open your Applications folder and check the "Install OS X El Capitan" box. If it's not there, open the App Store and click Buy, then click Download next to El Capitan. Wait until the file is completely downloaded.

1. Attach a USB storage device.

2. Open Disk Utility.

3. Select the volume (under External) from the sidebar. Volume is the top section, not the section (which is at the bottom).

4. Click Erase.

5. Make sure the Name field is set to Untitled. Don't change it. Click Erase.

6. Open terminal.

7. Cut and paste the following line into the terminal:

sudo / Applications / Install OS X El Capitan.app/Contents/Resources/createinstallmedia -volume / Volumes / Untitled / -applicationpath / Applications / Install OS X El Capitan.app/

You will need to enter the administrator password. Then enter "y" and press Return. It will first drain your flash drive and then turn it into a bootable installer.

8. Wait until the process completes completely.

If this process is a bit complicated, then consider downloading DiskMaker X. This program automates the process of creating an OS X installer

How to Recover a Mac Without a Recovery Partition: How to Use the Bootable OS X Installer

Then follow these steps to use the bootable installer:

Make sure the bootable OS X installer (USB stick) is connected.
Turn off your Mac.
Hold option and press the Power button.
A boot device list window will appear with a yellow disk with the OS X El Capitan installation underneath it.
Select it and press Return. Wait until the progress bar fills.
Select Disk Utility.
Select the drive under Internal (Primary Hard Drive).
Click Erase.
Give the disk a name; "Macintosh HD" is traditional, but you can choose. Make sure the format is OS X Extended (Journaled) and the layout is GUID Partition Map.
Click Erase.
Click Finish.
Select Disk Utility > Exit Utility.
Select Install OS X and click Continue.
Follow OS X settings.
Select Macintosh HD as the installation disc if present and click Install.

OS X will now be installed on your hard drive from the bootable OS X installer. The entire process may take about half an hour. You will then have a blank installation of OS X along with a new recovery partition.

It refused to boot. CMD+R Does not help. What should I do?

The start of the working day did not foretell anything bad. A cup of coffee, a good mood, the Power key and the MacBook displays the following sad picture:

A worrying thought immediately flashed through my head about the safety of the data, the current version of the TimeMachine backup (which was not at hand) and the possible loss of information.

Attempt No. 1. Booting into recovery mode

Being an interested user and an avid Mac user, I immediately tried to start the MacBook in recovery mode by holding down the keys CMD+R. Instead of the usual disk utility, the system greeted me with a window with an attempt network recovery.

Having chosen my home network, I began to wait for further developments. After a few minutes, OS X's recovery progress was interrupted error -4403F.

Attempts to start the process again led to exactly the same result. Rebooting the router confirmed that everything was fine with the network connection.

Trying to carry out diagnostics, fix possible hard drive errors, or simply reinstall the system was now out of the question. Section with Recovery HD, in which the tools for restoration are stored, ordered to live long.

Attempt No. 2. Resetting PRAM and NVRAM

Mac computers were created by highly qualified engineers, so the correct organization of the entire system and the presence of “hidden hardware reserves” allows you to avoid a number of interruptions in its operation. One of these reserves is memory sections PRAM And NVRAM. It stores settings data that is not reset even after the computer is disconnected from power. To revive the fallen system, a decision was made reset PRAM and NVRAM settings.

1. Turn on the Mac.
2. After the white screen appears, quickly press the key combination CMD + Option + P + R.
3. Hold until the Mac reboots again and the Mac greets the sound.

PRAM and NVRAM reset completed.

Although they say that hope dies last, it, lifeless and barely alive, continued to lurk in my mind. Resetting PRAM and NVRAM did not affect the error when booting the system. The MacBook continued to test my nerves.

Attempt No. 3. Reset SMS

Having become accustomed to storing all the necessary data “in the cloud” or on removable media, the simplest solution to global problems has always been to reinstall the system “from scratch.” This case was special. I needed data stored in memory and I needed a working Mac today.

In the Mac environment there is something called system management controller SMC. The stability of the entire system depends on the reliability of its operation. Resetting SMC settings can cure a number of problems like:

— constantly high rotation speed of the cooler even at minimal load;

— freezes when the system goes into sleep mode;

— errors related to the operation of additional peripherals or external monitors, as well as correcting system boot problems.

To reset the SMC, follow these steps:

Laptops with built-in batteries

1. Turn off your MacBook and plug in the power adapter.
2. Press and hold the keys at the same time Shit + Control + Option + Power and hold until the MagSafe adapter indicator changes color.
3. Release all keys and press the key again Power.

Laptops with removable batteries (older models)

1. Turn off your MacBook and unplug the power adapter.
2. Remove the battery from the laptop.
3. Hold down the key Power And hold for at least 5 seconds.
4. Release Power, insert the battery and connect the power adapter. Turn on your laptop.

Desktops (iMac, Mac mini, Mac Pro)

1. Completely disconnect the computer from the mains power.
2. Wait at least 30 seconds.
3. Connect the power and wait another 5-10 seconds and then turn on the computer.

The above actions can become really effective and the system will start. In my case, a miracle did not happen.

Attempt No. 4. Recovery using a bootable USB flash drive

An attempt to revive the system using the above actions was unsuccessful. The only option left was to reinstall OS X using a bootable USB flash drive. For this step you will need:

another computer running the OS X operating system;
Flash drive with a size of at least 8 GB.

Preparing a flash drive

1. You will need to download the OS X Yosemite distribution from the Mac App Store.
2. To create a bootable USB flash drive, download the DiskMaker X utility (distributed for free). You will need it to deploy the distribution.
3. Format the flash drive using Disk Utility in Mac OS Extended (Journaled).

4. After the distribution has finished downloading, cancel the proposed installation and run the utility DiskMaker X.
5. Choose a system Yosemite (10.10). The utility will detect the distribution in the Applications folder. Click Use this copy(use this copy).

6. Select the drive installed in the USB port and agree to the warning about completely deleting all data present on the flash drive.

7. The process of mounting the distribution kit with OS X Yosemite to the drive will begin.

The copying process takes about 10-20 minutes and depends on the writing speed of the USB flash drive. During mounting, dialog boxes and folders may occasionally open on the screen. Do not pay attention.

Once the OS X Yosemite image has successfully deployed, remove the drive.

System installation
1. Insert the flash drive into the USB port of the “problem Mac”, press the key Power and hold down the key Alt.
2. In the list of available partitions for downloading, select OS X Base System. Please note that there is no Recovery partition..

3. The Mac will boot into recovery mode. After selecting the main system language, the installation menu will open. In the top menu you will find a standard list of utilities.

Use disk utility and first try to check the access rights to the system partition and correct any errors. If after rebooting the system still refuses to boot, you will need to separate a partition of at least 20 GB in size in order to install a new system. You can find detailed instructions on how to partition a disk here.

From the same menu, you can either begin the process of installing the system on a newly created partition, or restore the system using a TimeMachine backup (see Working with TimeMachine).

CAREFULLY! Be careful when choosing the installation partition. The installation must be carried out not on top of the old partition, but on a newly created one.

After the installation is complete, you will have access to all the data located on the “damaged” partition with the old version of the system.

If you cannot create an additional disk partition

If for some reason you were unable to create an additional disk partition to install a new version of OS X, and saving the data remaining on the broken partition is still a priority, there is an option to install OS X using a previously created bootable USB flash drive on an external drive.

In Disk Utility, format the partition scheme to GUID Partition (Attention! All data on the external hard drive will be erased) and select formatting type Mac OS Extended (Journaled).

Installing the system on an external drive otherwise completely duplicates the method described above. By booting from an external hard drive, you will have access to the data remaining in the old system.

It refused to boot. CMD+R Does not help. What should I do?

The start of the working day did not foretell anything bad. A cup of coffee, a good mood, the Power key and the MacBook displays the following sad picture:

CAREFULLY! Be careful when choosing the installation partition. The installation must be carried out not on top of the old partition, but on a newly created one.

After the installation is complete, you will have access to all the data located on the “damaged” partition with the old version of the system.

After downloading the update from the Appstore, proceed as follows:

Launch Disk Utility;
In the left panel, select the drive, on the right, go to the “Disk Partition” tab;
In the "Partition Scheme" menu, select "Section 1". The disk name is "Yosemite", the format must be "Mac OS Extended (Journaled)".
Go to "Options", select the GUID partition scheme. Click "Apply".
Disk Utility begins formatting the flash drive.
From the "Utilities" folder, launch "Terminal".
To create a flash drive, run the following command:

Enter the administrator password.
It will take 10-15 minutes to create a bootable USB flash drive.
After the procedure is successfully completed, reboot the Mac. When loading, hold down Alt.
You are ready to install Mac OS X Yosemite.

Installing Yosemite

After creating a flash drive and rebooting the Mac, follow the instructions:

Go to the "Downloads" menu and select "Mac OS X Installer".
You need to open Disk Utility and select the disk with the system to format. Go to the "Erase" tab.
In the "Format" menu, "Mac OS Extended (Journaled)" must be selected, and the name of the disk is written.
Click "Erase", thereby starting the disk formatting process.
Close Disk Utility and open the Install Mac OS X section.
We specify the Yosemite boot disk and start the installation process.

Starting the installation process involves following the installer's instructions. Select the necessary parameters, the system will soon be ready for use. After installing Mac OS Yosemite, you can start using the system from scratch or transfer files from Time Machine.

Reinstalling Mac OS X Yosemite

If OS X Yosemite is already installed, you may need to reinstall it in the following cases:

System failures;
Errors when installing updates;
Disk cleaning;
The need to restore factory settings.

So, let's answer the question, how to reinstall Mac OS X Yosemite. To do this, you need to erase your Mac data and reinstall the system. Don't forget to back up your valuable files. To restore factory settings, you need to use the built-in recovery disk. To reinstall the system, an Internet connection is required, as well as a connected power adapter.

The procedure is simple:

Restart your Mac. During boot (gray screen), press Command+R.
Select "Disk Utility" and click "Continue".
Select the disk and click "Erase".
In the "Format" section, select Mac OS Extended (journaled), enter a name, and click "Erase".
The disk will take some time to clear.
Select "Disk Utility" and click "Finish".
Go to "Reinstall OS X", click "Continue".
Select the disk to use. In most cases it is the only one available.
We follow the installer's instructions and finish.
The system has been reinstalled!

Chapter 4

There is a problem - there is a solution

In Disk Utility, format the partition scheme to GUID Partition (Attention! All data on the external hard drive will be erased) and select formatting type Mac OS Extended (Journaled).

In order to restore the system we need:

External media with Mac OS backup;

Mac Book, Mac Book Pro, Mac Book Air, iMac, Mac mini;

About an hour or less, depending on the size of the backup and the speed of the Mac.

1 step. Connect the Time Machine backup media to your Mac.

Step 2. Restart your Mac by clicking the Apple menu in the top left corner and selecting Restart.

Step 3. As your Mac boots (a gray screen appears), press and hold Command (⌘) + R.

Step 4 Select the external media with the backup, the recovery disk and the date of the backup to be restored.

Immediately after downloading the OS X utilities, select "Restore from Time Machine Backup."

Read the general information and click "Continue".

Select the recovery disk (the media on which the backup is located).

The next step is to select a backup copy, I recommend choosing the most recent one, since it will save the latest changes in the system.

After this, you need to select the disk to which the system will be restored.

At the end, a message will appear stating that the restoration was successful, after which the Mac will restart and the next time you boot you will see the restored Mac OS X.

Recovering data from Time Machine backups.

In order to recover files (photos, videos, music) made using Time Machine, log into Time Machine by clicking on the icon in the upper right corner and select "Login to Time Machine".

If your backup media is not connected, you will see the error “Your Time Machine backup drive cannot be found.” To fix this error, connect the media to your Mac.

If the media is connected you will see an interface that allows you to travel back in time and view early changes to your files using the arrow or timeline on the right side of the screen. To restore files, select one or select several and click the "Recover" button.

In my opinion, file/system recovery has never been as elegant, beautiful and easy to do as in the Time Michine utility.
