Bootable flash drive eset how to make. Review of boot disk from ESET. Booting from eset livecd disk
At the moment, there are several antiviruses that distribute LiveCDs with antivirus to check the system for viruses in a completely clean system. Some viruses can be protected from removal if you run an antivirus on an infected system. When booting from a LiveCD, a known clean system (something from the Unix or Linux family) is loaded, and the antivirus will be able to avoid the effects of already picked up viruses.
One of these antiviruses is ESET sysrescue: http://www.esetnod32.ru/.download/livecd/
The original image is functional, but is designed to be written to either a CD/DVD or given the entire flash drive for his use. In this post I will tell you how you can use ESET sysrescue on a multi-boot flash drive (creating such a flash drive is not considered).
As already mentioned, the original image can be burned either to a CD/DVD or to a separate flash drive following the instructions from ESET. True, if we use a CD/DVD, our antivirus databases become outdated very quickly, and we can only update them by burning a new disc. And giving away an entire flash drive (currently less than 1GB and cannot be found everywhere) under one antivirus of 190 MB is stifling to the toad. And then there is a desire to add an antivirus to a multi-boot flash drive, which already has several useful images and still has some free space left.
When using a multi-boot flash drive, you just want to write the original ISO onto the flash drive and write down the rules for booting from it. But we will encounter the fact that after starting the system, the search for the “sysrescue” directory in the root of the available disks will fail, and the download will be interrupted with an error.
Here's why this happens:
- The loader of a multi-boot flash drive (for example Grub4DOS) maps the eset_sysrescue.iso image into memory and starts booting from it.
- When the system boots from ISO, external devices are initialized
- Now the loaded system sees the disks of the target computer and our flash drive, and the sysrescue directory is really nowhere to be found
You can simply add the sysrescue directory from the image to the flash drive and everything will work well, but the toad begins to choke again - 190 MB of files from the sysrescue folder are on the flash drive twice, and once completely empty (in the image file).
Here we can say a special thank you to ESET, since the image file contains everything that is necessary to create a new image with the files we need. True, for this you will need to unpack the image, throw out the files unnecessary for the image and assemble the image. Doing this manually (especially several times) is not very convenient, so I wrote a small script that will simplify the creation of a reduced image for recording on a CD/DVD disk or flash drive, and will also extract files from the image that need to be copied to the flash drive.
The script needs to be placed in the directory with the original image, as well as two files (7z.dll, 7z.exe) from the 7-Zip project. After running the script, a new file eset_sysrescue_min.iso will appear, as well as a flash folder, the contents of which must be copied to the root of the flash drive.
To boot from the original and reduced images, the following Grub4DOS configuration is suitable:
title ESET sysrescue
find --set-root --ignore-floppies --ignore-cd /eset_sysrescue_min.iso
map —heads=0 —sectors-per-track=0 /eset_sysrescue_min.iso (hd32)
map --hook
chainloader (hd32)
And today I want to write about boot disk from ESET. I will try to write a detailed guide with this disk, I will tell you where to download it, how to run it on your computer and what problems it can handle. I think it's okay if I compare the ESET disk with the Dr.Web disk a little.
What is an ESET boot disk?
Honestly, I'm a fan (loudly said :)) of antiviruses from ESET. I have this antivirus on my computer and I recommend it to everyone, as I am completely satisfied with it.
And when I saw somewhere on the Internet that ESET had created a boot disk, I became very interested in trying it out; before that, I had used a disk from Dr.Web.
Oh yes, something took me in the wrong direction. So what is an ESET boot disk? Essentially, this is a disk image that you can download for free from the ESET website, burn this image to a disk or flash drive, and use it to solve many problems.
What kind of problems can be solved with such a disk? Well, since it was released by an antivirus company, it was primarily created to fight viruses, and most importantly, ransomware viruses. The ESET disk even has a special utility for destroying ransomware viruses, I’ll tell you more about it later.
But this disk contains not only an antivirus, there is also an equally useful explorer that can be used to save files during a system crash, there is a browser and a couple of other useful features, but first things first.
How to download and burn a Live CD from ESET?
You can download the .iso disk image, as I already said, from the official website of ESET at the link http://www.esetnod32.ru/.download/livecd. When you click on the link, you will see this picture:
Next, just click on the “Download” button and a window will immediately appear asking you to save the .iso image to your computer, save it, it weighs a little more than 200 MB. You can also download the manual below, by the way, I really liked the manual, everything is very cool and clearly laid out.
After the disk image is completely downloaded to the computer, we need to burn it to a disk or flash drive.
I recommend burning to disk using my favorite program UltraISO. Download it, install it, and the .iso image will immediately launch in this program. You just need to click on the record button and wait for the recording to finish.
You can also record using a standard Windows tool.
Right-click on the downloaded image.
Select "To open with" And “Windows Disc Image Burner”
All that remains is to click on the “Record” button and wait for the recording process to complete.
A bootable USB flash drive with this image can be created using the Flashboot program, as promised, there will be a separate article about this.
This means insert the finished disk into the drive and restart the computer. If you boot from the drive and you see a window for loading a LiveCD from ESET on the screen, then you can skip the paragraph below and go straight to the description of choosing a boot mode.
After ESET starts loading the disk, you will see the following picture on the screen:
On the loading screen, 4 loading options will appear.
- "ESET live-CD Graphics mode"– this mode will allow you to launch a disk with a graphical shell and conveniently work with the system. It is recommended to choose this one.
- “ESET live-CD Copy to RAM” – in this boot mode, all files will be copied to RAM and the system will work without a disk or flash drive.
- “ESET live-CD Text mode” – from the name it is clear that this is a text mode, that is, you can work with the disk through the command line.
- “Run Memtest utility” is a utility that can be used to check RAM for errors.
Select the first option and press “Enter”.
We wait a little, and we see the desktop of the LiveCD system from ESET.
Basic utilities in ESET LiveCD
I will make a small review of only four, in my opinion, main utilities, the shortcuts of which are located on the desktop.
This is an antivirus scanner. With its help, you can scan your entire computer for viruses and possibly destroy those viruses that prevent your computer from starting. Since the operating system is not running during scanning, it will be easier for the antivirus to find and clean most viruses.
Userinit_fix
This utility was created by ESET specifically to combat ransomware viruses. So, if your computer has been affected by a ransomware virus, then you simply need to try using this utility. Launch it and follow the instructions.
Internet
The built-in browser allows you to visit any site without even starting the operating system. This can be useful, for example, when the computer gives an error and through the built-in browser it is possible to search for a solution to the problem on the Internet.
Computer
This name hides a file manager that will help you transfer files from one partition to another (convenient when reinstalling Windows), or perform other operations with files.
I liked the file manager in the ESET boot disk much more than in the LiveCD from Dr.Web. It is more functional and understandable.
These four utilities are the most basic and most useful. But there are other programs on the disk. They are hidden in the start menu (blue icon in the lower left corner). I won’t list them; you can figure them out yourself.
I was also pleased with the large number of system settings.
conclusions
A boot disk from ESET is another useful tool for restoring a computer in the event of a virus attack or other system errors. If we compare this disk with the disk from Dr.Web, then both of them deserve attention. The only thing is that the system from ESET seems to me to have a better interface and more settings, but this is not for everybody.
I advise you to create such a boot disk for yourself just in case. It would be better if you didn’t need it, but let it be for yourself. Good luck.
Has your computer crashed due to viruses? The situation is not pleasant, but not critical, because you can download LiveCD ESET NOD32 for Windows 10, and with this utility you don’t even have to reinstall the OS itself. You can clean your PC, laptop or tablet in safe mode and return the OS to a fully working state. This LiveCD is considered one of the best solutions. And not only among free ones, but also among paid ones, while the software is completely free and constantly updated. The latest version is usually the most powerful, so we post a link to it.
Download LiveCD ESET NOD32 to fight viruses
LiveCD ESET NOD32 is a tool that should be in the arsenal of any Windows 10 device owner. If you don’t already have this utility, then you need to not only download it, but also burn it onto media. The advantage of this solution over most others is that you can record the program on all popular types of media at once, for example:- CD/DVD;
- USB flash drive;
- ESET live-CD Text mode – launches the OS with the ability to work via the command line;
- ESET live-CD Graphics mode – launching a safe environment with a graphical interface + access to the Internet;
- Run Memtest utility – device diagnostics;
If your operating system has become the victim of an insidious and invincible virus that cannot be eliminated by the efforts of an already installed antivirus program, then it needs help from the outside. Very often, malware is created precisely to completely neutralize the effectiveness of standard protective mechanisms or masterfully deceive them; in this case, the most productive way would be to use an external boot disk or flash drive, which will contain suitable utilities for scanning the PC and treating it.
An effective solution to this problem would be to use free antivirus NOD 32 in the form of a boot disk in Russian(LiveCD). You can boot from such a disk if you are using any version of the Windows or Linux operating system.
With its power, you can not only boot your computer normally, but also conduct a full scan of the entire system for viruses in order to cure or delete all infected files, as well as restore damage caused by the virus and improve the functioning of your computer.
Note that if you decide to download the NOD 32 antivirus for free with a trial period of 30 days, then after this period you will have to activate the version by purchasing a license, or activate the antivirus using another method - find fresh keys for Nod 32 for free.
Downloading a auxiliary antivirus that is not part of the overall infected system, but at the same time has full access to folders for deep scanning and disinfection, is your tactical advantage against a cunning and algorithmically thought-out virus that cannot be defeated in the usual way (it is often impossible to remove a virus in a working Windows environment).
As before Nod 32 antivirus can be downloaded for free from the official website or from our portal, which is then installed by double-clicking on the installer, however, to get the life-saving NOD32 LiveCD system, you can either download an ISO image of the disk from the eset resource and then rewrite it to removable media, or use the capabilities of the Live USB Creator program.
It is worth noting in advance that the ESET SysRescue program, although it includes modern cloud technology Live Grid, is not a full replacement for the usual daily antivirus program node 32, which is designed to work with the operating system every day until it is completely removed or updated.
To use this disk for the computer boot process, the PC must first be rebooted and, when turned on, enter the BIOS to change its settings - select boot media with GCD 32 (disk or flash drive). All the necessary instructions for settings, changing them, and the entire process in general can be gleaned from the files located on the disk in the common pdf format.
The ability to use an excellent boot disk with antivirus software is an effective and extremely effective system that can eliminate the most complex threats, as well as carry out scans in selective mode or in the Smart version.
If the user so desires, the NOD 32 antivirus program will issue a personal report in Russian about each file that even just could potentially be dangerous - and each program owner will be able to independently decide whether to delete or save the file. Based on the results of the entire computer scanning process, the ESET NOD32 LiveCD application provides detailed statistical information and graphically displays the state of the PC's security level. The antivirus moves problematic and other suspicious file objects to quarantine - they can be viewed, and then deleted or completely restored, and this operation on objects can be performed with literally one click of the mouse.
LiveCD ESET NOD32 - will help if viruses have invaded your favorite computer, when they multiply at the speed of thought and occupy all the living space on the disks, viruses literally take out the remains of your brain with their presence on the computer. Live CD ESET NOD32 is a boot disk with which you can quickly start your computer and restore the functionality of a disabled operating system.
The main advantage of LiveCD ESET NOD32 is that the program runs independently of the computer's operating system, while having access to the hard drive and the entire file system. This allows you to remove infections that in normal situations (for example, when the operating system is running, etc.) are simply impossible to remove.
To boot your computer using the ESET boot disk, you must:
1. Download ESET NOD32 Live CD file (.ISO)
2. Burn the ISO image to a CD at minimum speed (you can also write to a USB flash drive)
3. Install a CD (or USB flash drive) with an ESET boot disk image recorded on it, and restart the computer, having previously enabled booting from a CD (DVD) drive (or USB flash drive) in the BIOS settings.
For this:
A.) Launch the BIOS settings by pressing the Delete or F2 key (see documentation on the PC) when the computer starts.
B.) Using the arrows on your keyboard, select the Advanced BIOS Features tab and press Enter.
WITH). Select the First Boot Device tab, press the Enter key, in the window that appears, also use the arrows on the keyboard to place the pointer opposite the CD-ROM label (or opposite the USB Flash drive) and press Enter.
D.) Close the BIOS, while saving the settings, to do this, press the F10 key on the keyboard, after the red window appears, press the Enter key. The computer will reboot and if you have a CD (DVD) disk (or USB flash drive) with an ESET boot disk installed, it will boot.
4. When you load the ESET NOD32 LiveCD from removable media, a splash screen appears on the screen.
Usage
Once loaded, the ESET NOD32 LiveCD launches. ESET SysRescue is a full-featured on-demand scanner with support for updates and configuration.
