How To Create Windows 10 Recovery Drive
A recovery unit is a set of tools necessary to recover and correct the operating system if it has any problems when starting up. By booting from this unit, a system recovery environment will be started.
For this procedure, we will need a pen drive with a capacity equal to or greater than 16 gb.
To create this file, we will type recovery in the Cortana search box located on the taskbar. Among the first options of the search, a tool called Recovery will appear.
Clicking on Recovery will open the advanced recovery tools window and then we will click on the option “Create a recovery unit”. Remembering that the pen drive must already be connected to the USB port.
After clicking on the creation of the unit, the user account control window will open where we will click on “Yes”, as we will need elevated permissions to proceed.
In the next window, it will appear explaining the purpose of this recovery unit and also a field where we should leave it marked regarding the backups of the system files and then we will click on “Next”;
Then a running bar will appear, searching for external devices that can be used to create the recovery tool.
When the scan is finished, the connected external device will appear. The next screen requests a device with at least 4 Gb of capacity. But, as we are selecting the option of system file backups, we will need a 16 Gb pen drive.
When checking that you have located or external device, we will click on “Next”.
In the next window a message will appear reminding you to make backups of your personal files in case of any problem, and then we will click on “Create”.
Now just wait while the tool creates the recovery unit.
When finished, the message that the recovery unit is ready will appear and then we will click on “Finish”.
Now that the recovery unit is ready, just to check if this unit was created, we will enter Windows Explorer and see that the recovery unit with the size of 12 gb was created.
To verify that the drive is working, we will start the computer with the first boot option from the USB drive.
When starting the unit, the first screen that will appear will be to select the keyboard layout and then we will click on the <Enter> key to proceed.
As we want to solve the problem when starting Windows, we will select “Troubleshooting”.
As in this case, we just want to check if this recovery unit is accessing all its options, we will select “Advanced options”.
We will note that we can use command lines to correct any problems as well as restore the system to a previously recorded point (remembering that the system restore must be enabled for recording restore points) among other options.
You should see the Windows recovery unit working perfectly.
We started the computer through the USB drive to get an idea of the screens that will be presented for the repair and recovery of the system.
As in this part of the tutorial, the goal was just to create this device and in order not to get too extensive. I have explained how to use this tool below.
How To Use Windows 10 Recovery Drive
In the previous part, it was demonstrated how to create a Windows 10 recovery drive and also how to boot the computer through this drive.
In this part, we will demonstrate how to use this drive to recover or repair the operating system.
One of the most important tools that Windows has, in case there is a problem with installed software, system updates, among others, is the “System Restore”, which can also be used from the system recovery unit – if the Windows does not boot.
In Windows 10, by default the installation, this tool is disabled. So if there is a problem with the operating system, you will not be able to restore the system to a point before the problem.
So, as the system is running perfectly, let’s activate the System Restore tool and create a restore point. As you install new software, updates or other modifications to the system, with this restore tool enabled, the system automatically creates restore points.
How To activate the system restore in Windows 10.
In the Cortana search box located on the taskbar, we will type system. The first option of the search is “System” which is in the control panel and is the one we will click on.
The system information window will open. Then we will click on “Advanced system settings”, which is the last option located on the left side of the window.
The “System Properties” window will open and then we will click on the “System Protection” tab. Within this tab, we will click on the “Configure…” button.
In the window to configure the system protection, we will leave the option “Activate the system protection” that refers to “Restore Settings” selected and then we will be able to click on “OK”.
We will notice that the local disk C protection settings will be enabled.
Since Windows 10 is working perfectly, we will click on “Create…” to create a restore point from that moment.
We define a name for the restore point and click on “Create”. Then just click “OK” in the system protection window to activate it.
Now that everything is ready, suppose there was a problem with Windows and it cannot start.
With the system recovery unit (USB) connected to the computer, we will boot this PC leaving the recovery unit as the first boot option.
The first option that will appear when loading this unit will be to define the keyboard layout.
Then we will click on the option “Troubleshooting”.
On the next screen, we will click on “Advanced options” to expand the available recovery tools.
If the case of the Windows problem refer to undoing the latest changes to the system, which may be preventing it from starting, we can then click on the first option which is “System Restore”.
In “System Restore”, we will click on Windows 10, which is the system that needs to be restored.
The window that will open to restore files and settings, we will click “Next”.
In the next window, all restore points that the system created manually or automatically will appear.
We will select the restore point that suits us. Here, in this case, only what we have just created will appear and then we will click on “Next”, which will be enabled after selecting the restore point.
The window will appear to confirm the restore point and then we will click on “Finish”.
A new confirmation window will appear, we will click on “Yes”.
At this point, the restoration procedure will be running, so we just have to wait.
At the end of the restoration we will click on Restart to make the system work again. Remembering that, at this moment, it is necessary that the computer boot is done by the HD and not by the recovery unit. If, even after the restoration, Windows continues to have problems when starting, we can boot again from the recovery unit and select another restore point that the system created.
Another very useful option for the system recovery unit is the “Command Prompt”, where we can copy documents and personal files from the hard drive as well as try to correct the system boot in case any boot file is corrupted.
Note that, in the case here, the local disk will have the “E” drive and the pendrive is as the “D” drive. From this information, we can make copies of files that are on the HD if a new installation of Windows is inevitable.
Another option that we may be doing from the command prompt is scanning to try to correct system startup and bad sectors. For this we will use the command “chkdsk e: / R”, where “e:” refers to the local disk and “/ R” to try to correct the system’s boot and scan for bad sectors.
Note that this instruction is divided into some stages, which will be executed sequentially.
If you still have problems with Windows, you can use the “System image recovery” option on this recovery unit. For this option, you will need to have a Windows backup image to restore it.
When clicking on this option, the window for selecting the image will appear and then you must click on “Next”.
If no system image is available, we can click on the Advanced button to manually search for this image.
We will click on “Search for a system image on the network”.
A window will open to confirm the connection to the network and then we will click on “Yes”. Then you will ask to inform where this system image will be.
Another interesting option of the recovery unit is “Back to the previous version”. If you have a problem with the Windows 10 Build, you can go back to the previous Build by clicking on “Back to the previous version”.
This last boot repair option does not always work depending on the Build that is installed. In this case, we can do it through the command prompt as shown above.
USB drive that causes physical damage to the computer exists
Device called USB Killer and created by a Russian can release 220 volts in the USB port by burning the motherboard of almost all devices.
Some users are asking about a new device that when inserted into the USB port of the notebook or computer, causes your motherboard to burn instantly. Yes, this device exists and was created by a Russian specialist in digital security, known as “Dark Purple”.
This pendrive is called USB Killer and is visually the same as the others on the market, but inside, the hardware is not used to store data, but to discharge a strong current of -220 volts.
That’s right, the usual USB port where we attach USB devices, such as pendrives have a voltage of 5 volts and a current of up to 500mA. Imagine the board receiving a voltage of 220 volts? It certainly can’t take it and “fries” in just a few seconds.
This new device launched this week is an “evolution” of the previous one that discharged -110 volts. According to the author who created this computer destroyer, it can burn almost all notebooks, tablets, cell phones and computers with USB input. It has not yet been tested on other devices such as TVs, home theater and video games, but you can probably burn them, since the voltage is high.
If we already had to worry about malware that infects USB devices and spread to infect other computers, now we have to be extremely careful with these suspicious pendrives, causing a huge headache for the user who is “trolled”.
Although the notebook shown in the video was burned, Dark Purple says that just changing your motherboard to get it working again, not affecting the other hardware connected to it, such as the HD or SSD where the information is stored.
