• System Reserved.
• Untitled (Recovery partition).

In chapter System Reserved The boot store configuration files (BCD) and the system boot loader (bootmgr) are stored. In this way, the system protects the boot files of the operating system and, using this section you enter the system recovery environment.

If as a result of damage system files the operating system loses its functionality and does not boot, you can restore them using the recovery environment. You can launch it by pressing during start the computer key F8.

Launching Recovery environment, select item System Restore or Troubleshoot your computer. The names of menu items may vary depending on the version of the operating system and the method of launching the Recovery Environment.

Hi all.
We all know that if any problems arise with the system, it can be reinstalled. The Recovery section helps us with this. During a clean installation of the system, it is created automatically, but it happens that you install macOS after Windows (which is incorrect) or you accidentally/intentionally deleted the Recovery HD partition. What to do in this case, if the system is already installed, but it is not possible to tear it down and reinstall it?

Perhaps there is a similar solution floating around the Internet, but I will describe it as I did.

A little background.

I had macOS 10.13.1 developer beta installed on APFS. Since the work of this file system I wasn’t happy with it, I wanted to upgrade to HFS+ through a clean reinstallation. The trouble was that Windows was already installed, and after deleting the APFS container, the Recovery partition disappeared. For some reason, system 10.13 refused to install for me, so I restored backup 10.12.6 from Time Machine to an empty partition. After recovery, the Recovery partition did not appear. I easily updated from 10.12.6 to 10.13. There was still no recovery partition.

A couple of days ago I decided to upgrade from 10.13 to 10.13.1, and what was my surprise that the installation of the system at the final third stage simply did not reach the end and threw it on the desktop with an error.

A couple of days later, yesterday, I also tried to install the system, and got the same error.
After thinking briefly, I immediately realized that the error was the absence of a Recovery HD partition. Accordingly, I started googling how to restore it. There were many methods, they were all written during the reign of Tsar Pea, and they were not suitable.

I decided to do something simple: what if I cut off the partition from the system manually, get files from the Recovery partition from the system backup, and assign the partition type to Apple_Boot? This is what I will describe in the next steps.

Creating a Recovery partition.

1. Separate a new section.

This is what my disk layout looked like using the “diskutil list” command.

╭─[email protected]~ ╰─➤ diskutil list /dev/disk0 (internal, physical): #: TYPE NAME SIZE IDENTIFIER 0: GUID_partition_scheme *120.0 GB disk0 1: EFI EFI 209.7 MB disk0s1 2: Apple_HFS Macintosh HD 78.9 GB disk0s2 3: Microsoft Reserved 134.2 MB disk0s3 4: Microsoft Basic Data Windows 40.0 GB disk0s4 /dev/disk1 (internal, physical): #: TYPE NAME SIZE IDENTIFIER 0: GUID_partition_scheme *500.1 GB disk1 1: Microsoft Basic Data Files 151.3 GB disk1s1 2: Apple_HFS Time Capsule 348.7 GB disk1s2

As we can clearly see, there is no Recovery HD partition after Macintosh HD.
In Disk Utility, I separated the 650MB partition from the main one.

After that, the markup looked like this:

╭─[email protected]~ ╰─➤ diskutil list /dev/disk0 (internal, physical): #: TYPE NAME SIZE IDENTIFIER 0: GUID_partition_scheme *120.0 GB disk0 1: EFI EFI 209.7 MB disk0s1 2: Apple_HFS Macintosh HD 78.9 GB disk0s2 3: Apple_HFS Recovery HD 650.0 MB disk0s3 4: Microsoft Reserved 134.2 MB disk0s4 5: Microsoft Basic Data Windows 40.0 GB disk0s5 /dev/disk1 (internal, physical): #: TYPE NAME SIZE IDENTIFIER 0: GUID_partition_scheme *500.1 GB disk1 1: Microsoft Basic Data Files 151.3 GB disk1s1 2: Apple_HFS Time Capsule 348.7 GB disk1s2

2. Change the partition type.

Everything seems to be correct, but there is one thing. The Recovery partition type must be Apple_Boot, not Apple_HFS. Well, let's change it. Open a terminal and enter the commands:

Diskutil unmount /dev/disk0s3 sudo asr adjust --target /dev/disk0s3 --settype "Apple_Boot"

Attention:/dev/disk0s3 numbers may differ for you!

Check the output of the diskutil list command. Let's make sure everything is correct.

╭─[email protected]~ ╰─➤ diskutil list /dev/disk0 (internal, physical): #: TYPE NAME SIZE IDENTIFIER 0: GUID_partition_scheme *120.0 GB disk0 1: EFI EFI 209.7 MB disk0s1 2: Apple_HFS Macintosh HD 78.9 GB disk0s2 3: Apple_Boot Recovery HD 650.0 MB disk0s3 4: Microsoft Reserved 134.2 MB disk0s4 5: Microsoft Basic Data Windows 40.0 GB disk0s5 /dev/disk1 (internal, physical): #: TYPE NAME SIZE IDENTIFIER 0: GUID_partition_scheme *500.1 GB disk1 1: Microsoft Basic Data Files 151.3 GB disk1s1 2: Apple_HFS Time Capsule 348.7 GB disk1s2

3. Transfer the contents.

Now all we have to do is drop Recovery files partition from backup.
I’m sharing my backup with you., it is from the system 10.13.1, I have not checked the performance with 10.12.6.

You need to put the com.apple.recovery.boot folder in the root of the Recovery HD partition, before that you need to mount it with the command:

Diskutil mount /dev/disk0s3

This is what the contents of the Recovery partition will look like:

ClockworkMod Recovery - recovery for android devices, an alternative to the factory one, with many useful functions: creating backups, restoring the system from a backup, installing firmware and much more.

Any user of a device running on the Android OS who is just beginning to delve into the essence of this operating system, visiting various forums, blogs and websites someday, will definitely come across a rather strange and mysterious name - ClockworkMod Recovery. Most often, it is mentioned when it comes to replacing the kernel, flashing the firmware of a smartphone or tablet, and other “hacker” frauds.

Many people are probably wondering what kind of ClockworkMod Recovery this is, and also, what is it for and what to do with it? These are the questions I will answer in this article, in the form full instructions Operating instructions for ClockworkMod Recovery.

Recovery. What is it?

All devices running on the ANDROID OS have a factory recovery, which, if necessary, can be loaded when you turn on your smartphone or tablet using a special key combination. The factory utility, as a rule, can clean the system and install OS updates from the update.zip file.

What is ClockworkMod Recovery and what is it for?

ClockworkMod Recovery is a utility for working with the system, an order of magnitude more powerful than the built-in factory one. Thanks to it, you can create complete backup copies of the operating room Android systems, and also install various software and all kinds of kernels and firmware on the device, and much more that factory recovery does not perform. ClockworkMod Recovery is installed instead of the factory menu, in a special department internal memory device

There are situations, seemingly hopeless, in which ClockworkMod Recovery can help. For example, if a smartphone or tablet cannot boot for any reason, this utility will help restore the operating system, with all its applications and settings.

Below are some of the most important operations that can be performed using ClockworkMod Recovery:
1) Connect to a PC via a USB cable when using removable storage mode.
2) Install unofficial kernels and custom firmware.
3) Install factory system updates, as well as various fixes and additions.
4) Restore the device using a previously created copy.
5) Work with the ADB program by connecting your device to the PC using a USB cable.

ClockworkMod Recovery utility was designed and subsequently created by developer Koushik Dutta, known under the pseudonym Koush. For most devices running Android OS, there are CWM versions.

Installing ClockworkMod Recovery

It can be noted that for most devices, installing the ClockworkMod Recovery utility is a fairly simple procedure. To do this, you just need to download and install the program from the Market and run it. The first item in the menu will be to install ClockworkMod. For other smartphones and tablets, there are other separate utilities that are similar to the application used on the tablet Iconia Tab. Well, or you can install ClockworkMod Recovery on them, but only with the help ADB programs, which is integral part Android SDK and you can download it.

Launching ClockworkMod Recovery

You can load your device into ClockworkMod Recovery in several ways.
1) Using the ROM Manager program, you will need to select an item in the menu called “Load Recovery Mode”.
2) Using a specific key combination, when turning on Android devices. Most often, the combination depends on the brand and model of the tablet or smartphone. But in most cases, this is a combination of pressing the volume down rocker and the power key at the same time.
3) Using the ADB program. When setting up the connection of your device to a PC using this program, in order to boot the device you will need to enter the “command”: adb reboot recovery.

Analysis of the ClockworkMod Recovery menu

When you boot your tablet into the ClockworkMod Recovery utility, first of all you will see its main menu:

The screenshots were taken in version ClockworkMod recovery 3.0, one of the most popular and widespread. In other versions, including newer ones, the menu may change slightly, but, nevertheless, its main functions, as a rule, remain unchanged.
On many devices, moving through menu items occurs using the volume rocker. And in order to select a specific item, use the power button. But some Android devices may use other keys, for example, to return to the previous menu.

No matter what submenu you are in, in order to return to the previous menu, you can use the +++++Go Back+++++ item

Let's move on to the purpose of the main menu items:
1. reboot system – directly, reboot the device.
2. apply update.zip from sdcard - without a doubt, the item that is used most often than others.
Thanks to him it becomes possible installation official and custom firmware, as well as themes, kernels and other software, which must be in the update.zip file, and you must move it to the root of the memory card. For example, in file manager of a device running on Android OS - this is the /sdcard folder.
Once you have selected this item, you will automatically be taken to the following menu, in which you must confirm your choice by clicking on Yes – Install /sdcard/update.zip

3. wipe data/factory reset – full reset of settings, cache and data. That is, after you use this item, the device will return to the state it was in when it was sold in the store. CWM will clean the /data and /cache partitions in the internal memory of the device. And also from system folder".android_secure" located on the memory card, everything will also be deleted, including the sd-ext partition.
4. wipe cache partition – clearing temporary data accumulated while using the system and various programs, that is, cleaning the /cache partition located in the internal memory. Most often this item is used before starting installation new firmware or kernels.
5. install zip from sdcard - installs from a memory card, zip file. Once you select this item, you will automatically be taken to the following submenu:

And its points mean this:
1) apply /sdcard/update.zip - well, this item fully corresponds to the second item of the main menu “apply update.zip from sdcard”.
2) chooze zip from sdcard – this item is needed in order to select a .zip file on the memory card for installation.
This item is also similar to menu item 2 and is used to install various firmware, kernels, and other modifications. But there is still a difference - installation can be done from absolutely any file with a zip extension, having any name, and located anywhere on the memory card. After selecting this item, you will see the entire list of folders and files on the device’s memory card, from which you need to select a .zip file for further installation.

3) toggle signature veritification – enable and disable file signature verification.
When the signature check mode is enabled (Signature check: Enabled), installing firmware that has not been signed by the developer will become impossible. And the majority unofficial firmware, just without the developer’s signature.
4) toggle script assert – enable or disable the assertion script.
This item is needed for internal use in ClockworkMod Recovery, that is, you won't need it, so it's better not to touch it at all.
5) +++++Go Back+++++ - well, this item, as described above, is needed in order to return to the previous CWM menu.
6) backup and restore – this item is needed when creating and restoring device backups. Also, one of the most basic points of CWM. Thanks to it, you can make a complete backup copy of the tablet system, including all applications along with data located in the internal memory of the device. This procedure is also called “Nandroid backup”, which means “System snapshot”. This is necessary in order to return the smartphone to its previous state. It looks like this:

And its points mean this::
Backup – creating a backup copy of absolutely all partitions located in the internal memory of the device.
The copy, after creation, will be located on the memory card. Initially, the name of the backup consists of the time and date it was created. But it can be renamed. But you should remember that the name must consist of numbers and Latin letters, spaces and Russian letters are not allowed.
Restore – restore all partitions after selecting a specific backup.
After selecting this item, the entire list of available backups located on the memory card will open in front of you. To restore, you just need to select one of them.
Advanced Restore – this item means restoring only a specific partition from the backup you select.
The choice of any individual partition that you want to restore is yours: system, cache, sd-ext partition, data or boot. You can see more details in the screenshot below:

7) mounts and storage – an item thanks to which you can mount individual partitions, as well as format them and mount the device as USB storage when connected to a PC. After mounting, folders and partitions become available for use.

This menu consists of several items:
1. mount /system - mounts the system partition;
2. unmount /data – unmounts the partition with data;
3. unmount /cache - unmounts the partition with the cache;
4. mount /sdcard - mounts the device’s memory card;
5. mount /sd-ext - mounts Linux, namely, the ext partition on the memory card, if of course it is available;
6. format boot, format system, format data, format cache - formatting partitions corresponding to the names.

Important! Be extremely vigilant with these menu items. For example, formatting the system partition will completely destroy your OS, that is, the current firmware. And after you format the boot partition, the device will not boot.

Format sdcard - formatting the device’s memory card;
format sd-ext – formatting a Linux partition on a memory card;
mount USB storage – connects the device to a PC in removable device mode.

8) advanced – use of additional CWM functions.

This menu also consists of several items:
1. Reboot Recovery – reboots the device back into recovery;
2. Wipe Dalvik Cache - clears the cache of Dalvik - a virtual Java machine used to run various applications. Most often, this menu item is used before installing custom firmware.
3. Wipe Battery Stat - resets battery statistics. This item is most often used to reset incorrect battery meter information.
4. Report Error. This item allows you to report an error to the developers of the ClockworkMod utility. In this case, the error log is written to the device’s memory card and can be sent using the ROM Manager program.
5. Key Test – with this item you can check the functionality of the device buttons. It works as follows: when you press a button, its code is displayed on the screen.
6. Restart adb – restarts the ADB server. This item can be used if the device has stopped responding to commands from the ADB program when connected to a PC via a USB cable.
7. Partition SD Card. Using this item, you can create partitions on the device’s memory card. That is, you can create /sd-ext and /swap partitions on the memory card. The /sd-ext partition is needed for use by certain firmwares in case of insufficient internal memory of the device. And the /swap section is needed to speed up Android work devices.
8. Fix Permissions. This item will help correct access rights to partitions and files.
