Welcome! This blog is dedicated to the Internet and computers, or rather was dedicated to them.
It’s probably immediately obvious that no new articles have appeared on the site for many years. Yes, this is the fate of most blogs. This project was once an ambitious undertaking, and the author, like many others writing at the time, had ambitious plans to become one of the best Russian bloggers. Well, if you look now, of those blogs that were created simultaneously with mine, most have already disappeared into eternity. And I just simply didn’t have enough time to blog. So yeah, it's not updated anymore. Although we once won the “Runet Blog 2011” competition with this site.
I even had the idea of deleting all this, but then I reviewed the old materials and realized that they could still be useful to readers. Yes, some articles are outdated (if I have enough strength, they will be marked accordingly), but the site, for example, can be useful for beginners - here you can read about the basic concepts of the Internet, learn how to set up the Internet, Windows, or even decide to switch to Linux. So take a look at the categories and choose the one that suits you.
And yet, I hope that this is more than just a blog, but a real guide to the Internet. The site can be viewed in directory mode, where all available articles are structured by categories. And, who knows, maybe one day new high-quality articles will start appearing here.

Picodi.ru is a discount portal from International Coupons, a Polish expert in the field of savings and cheap shopping. The Poles are considered one of the most frugal nations in the world, so it is not surprising that this type of project grew out of the Polish startup kodyrabatowe.pl. How can this portal be useful to the average Internet user in Russia?
Modern Android phones are more than just phones. You get used to the set of installed programs, the history of your calls and text messages, your collection of photos and much more. But time passes, and the device that you were completely satisfied with begins to slow down, glitch, or simply loses its presentable appearance due to chips on the body or scratches on the screen. The question arises of choosing a new phone and changing the Android phone. And if we ignore the issue of choice for now, then “moving” to a new phone remains a serious problem - you absolutely don’t want to start all the data from scratch. This is what we will talk about today.
Most of the readers of this blog have most likely never encountered version control systems and will not encounter them in the near future. It's a pity. This extremely convenient invention is quite widely used by programmers, but, in my opinion, it could also be very useful for those who actively work with texts. But, probably, now there is not a single version control system that would be easy to start using for “office” (Microsoft Office) work. Nevertheless, I think that the material presented in the article may be of interest to all readers.
If you have been wondering how to watch movies online and access the Internet from your TV, this article is for you. No, I know that some TVs already have Smart TV functionality, but I have never seen it work properly. Apparently, this is why Google recently demonstrated an absolutely stunning device that immediately became a sensation. We're talking about the Chromecast media streamer, a more advanced and affordable version of last year's disastrous Nexus Q player.
The Chromecast dongle, whose dimensions do not exceed 2 inches, connects to the HDMI port of the TV and allows you to enjoy watching streaming web content. To control the streamer, you can use any device (tablet, PC, smartphone) based on the operating platform iOS, Windows, Android or Mac OS.
This article is devoted to the design of Android system memory, problems that may arise due to its lack and ways to solve them. I myself recently encountered the fact that my Android phone began to regularly display messages about low memory when I tried to install this or that application. Which was very strange for me, given that according to the description on the market there should have been about 16GB, and I also increased this volume using an additional memory card. However, there was a problem, and it took a lot of fiddling around before I found the right solution that didn’t require root access or completely restoring the phone to its factory state.
Hello friends! Today I will talk about how to BIOS configure booting from a flash drive, and what to do if this same flash drive is not displayed in the BIOS settings. I already wrote an article about that, but today I want to write in more detail about that how to boot from a USB drive, having previously configured the BIOS.
What is it for? Well, if you are reading this, then I think you already know why you need it. Well, if not, then I’ll tell you a secret: you can create bootable flash drives and install operating systems from them or launch other bootable disk images, for example. This is very convenient; flash drives are more resistant to mechanical damage compared to disks, and they can have more memory.
Before you start writing the instructions, be sure to read the article, it says how to enter the BIOS.So, you have already created a bootable USB flash drive and are ready to boot from it. First of all, we need to configure the system so that our flash drive comes first, and the system starts from it first. There is one joke here, through which questions arise such as the flash drive is not displayed in the BIOS settings.
Does BIOS not boot from a flash drive?
It's very simple, when the USB device is not connected to the computer, it will not appear in the boot options.
Setting boot from flash drive in BIOS
We do this: connect the flash drive, go to the BIOS (if you don’t know how, read the article above, usually these are the DELETE or F2 keys). And go to the page with setting the order of boot devices. I'll just show screenshots. Remember, everything may look different for you, and menu items may have different names. Look for the item with the word “Boot”.
If the flash drive is connected, we will see it in the list.
Now we need to install the flash drive in the first place in the boot list. To do this, press “Enter” and select “” .
We save all our changes by pressing F10 and restart the computer. If everything is done correctly and the USB drive is created correctly, the USB drive will begin loading. It may indeed be that USB is not displayed in the settings, most likely because you have an old computer and it does not support this function.
After a boring story about setting up the BIOS, I would like to advise you to think about the security of your home or office, and video surveillance, in my opinion, is the best means of protection. Moreover, with new technologies you can install IP video cameras, which will give you many new and modern opportunities. For example, creating a network from several cameras and even broadcasting the video to the Internet.

The appearance of a message on the monitor screen containing the words Reboot and select proper boot device completely confuses many users. Starting the operating system turns out to be impossible. But why? Next, it is proposed to consider the essence of this computer failure and apply several simple solutions to fix it. But to use them, you initially need to know, at least approximately, what actually caused such an unpleasant failure.
Reboot and select proper boot error?
Actually, the very nature of the error must be considered from the point of view of a purely technical translation of the message that appears.
In this case, it suggests restarting the computer and selecting the correct boot device. In general, the appearance of such a message indicates that starting the OS from the hard drive is impossible. By the way, the second line in the message suggests inserting bootable media and starting from it. Here you should understand that there are many interesting tools on recovery disks that allow you to fix such problems (for example, the command line). But first things first.
Possible reasons for the error
But why does a situation arise when a notification appears with the text Reboot and select proper boot device? In the simplest and most banal case, this can only be due to the fact that the user installed it for a removable device, and during the restart simply forgot to remove it from the drive or port. But the problems don't stop there.
Among the most common reasons for the appearance of the Reboot and select proper boot device message are the following:
- lost settings of the primary system (BIOS/UEFI);
- errors or damage to the hard drive;
- malfunction of the system boot loader;
- penetration of viruses into the system;
- power supply malfunction, etc.
BIOS settings and system boot options
The first step is to check the BIOS settings. In this case, the question of restoring the system boot after checking the installed components is to specify the hard drive as the first device.
This is done in the Boot section, where a line is selected that contains in the description something like Boot device priority or Boot sequence. Here you just need to put the hard drive in first place or use the PageUp/PageDown selection keys on the first line. It goes without saying that after this the set parameters must be saved (F10 + Y).
However, even after this, the new parameters may, as they say, “fly off”. On desktop computers, when booting, the line Reboot and select proper boot device appears again. Why?
The problem may be that the CMOS battery, which is located on the motherboard and is responsible for storing the set BIOS parameters when the terminal is turned off, has expired. Conclusion: the battery just needs to be replaced. Indirectly, the reason may be damage to the power supply or power surges. Here you will have to either try to replace the unit or install an additional voltage stabilizer.
The laptop may display Reboot and select proper boot device for a completely different reason. Very often this is due to the presence of a primary UEFI system rather than a BIOS, when the user simply does not have time to use the key combination to enter the settings interface. You will have to try to press the desired combination in time, but sometimes the inscription disappears, after which you can log in, use the power settings and uncheck the fast boot option.
The system writes “Reboot and select proper boot device”: issues with the performance of the hard drive
In some cases, when starting the boot, you can use the F9 or F10 keys, which help bring up the boot menu and select the desired disk or device. But this method is suitable for a one-time start. But if the problem is specifically in the hard drive, and the Reboot and select proper boot device line appears constantly, you will have to take drastic measures.
Errors on the disk are not the worst thing. You can check the hard drive and correct its condition from the command line when starting from the recovery disk (chkdsk /r/f/x/). But what to do if the failures are not software, but physical in nature?
You will have to check it taking into account surface testing. For this, one of the good tools is the disk utility Hiren’s Boot CD. A console program can also be used for checking, but its use can only be justified if the hard drive begins to “crumble.” But the first utility instantly fixes failed clusters and sectors.
Bootloader corruption
Finally, another problem may be that the hard drive has damage to the boot area and the boot tool itself.
Here you need to use the command line again when starting from removable media (usually it is called through the combination Shift + F10).
The three commands shown in the image above are used to restore. The first two are mandatory, the third - if they did not give the desired result when the computer system was restarted.
The situation with the boot loader malfunctioning may also be associated with the influence of certain types of virus threats (in this case, the Reboot and select proper boot device start line may also appear).
But you need to deal with such things exclusively with the help of programs with the general name Rescue Disk, which are written to removable media (optical disks or USB drives), and booting is carried out from them (naturally, setting such devices as priority ones for starting in the BIOS ).
Instead of a total
In general, only the main possible reasons why starting the operating system is impossible were mentioned here. Unfortunately, it is impossible to immediately say what was the primary source of the failure and what solution to apply to correct the situation. You'll have to act, as they say, at random. But, if we approach the issue purely from practical reasons, you should first check the parameters of the primary BIOS system, the state of the hard drive and restore (or even overwrite) the boot record. Perhaps such actions will help.
If none of the above methods work, then you will have to change the hard drive, since critical errors can be associated solely with the fact that it has begun to fail. There is nothing you can do about it, and, of course, it is completely naive to hope for the use of the HDD Regenerator program. No matter how good it is, it is simply not able to eliminate absolutely all problems with the hard drive.
When trying to install an operating system from a flash drive, the user may encounter the message “Start booting from USB device...” appear on the screen, after which the system freezes and nothing further happens. This is usually due to a situation where the bootable USB flash drive with the operating system was not created correctly by the user, so the system has problems installing a new version of the OS from this device. In this material I will tell you what the “Start booting from USB device” problem is, what its causes are, and how to fix the appearance of the message on your PC.
The screen with the frozen inscription “Start booting from USB device...” looks something like this
Translated, this text sounds like "Starting boot from USB device...", usually appearing when loading the installation version of Windows OS from a USB device.
The reasons why the “Start booting from USB device” message “freezes” are usually an incorrectly created installation flash drive, as well as incorrectly specified settings in the BIOS of the user’s PC.
How to fix “Start booting from USB device”
To resolve the “Start booting from USB device” error, I recommend doing the following:
- Check if your USB device is bootable. To do this, I recommend using the “MobaLiveCD” software tool, which will check the boot status of your flash drive. This program does not require installation, works immediately after launch, and is quite lightweight and easy to use.
Method 1. To work with MobaLiveCD, download and run this program with administrator rights. On the main screen, click on the “Run the Live USB” button, point the program to the path to your flash drive. If the program asks you « Do you want to create a hard disk image for your virtual machine?” — select “No”. The program will emulate the system startup from your flash drive, and you will see the result with your own eyes.
To exit the program, press the Ctrl+Alt keys.
To check the file system of your flash drive, connect it to your computer, right-click on the flash drive in Explorer, and select “Properties” in the menu that appears.
- Try changing the value of some BIOS parameters. Go to your BIOS and change the “Legacy” option from “Enabled” to “Disabled” (or vice versa). Save the settings, restart your computer, and try installing the system again from the flash drive;
Method 2. If the previous method did not help fix Start booting from USB device, try the following. Go to the BIOS, in the “Boot” tab, set the “Secure Boot” parameter to “Disabled” (if a warning appears, feel free to click on “Ok”). An additional option “OS Mode Selection” will appear, select “UEFI and Legacy OS” here (if a warning appears, then click on “OK” again). Click on F10 again, then on “Yes”, wait for the laptop to reboot.
Then we go to the BIOS again, in the “Boot” tab we select the “Boot device priority” option, in the first paragraph we select our flash drive as a boot device. Click on F10 and “Yes” again. We reboot our PC and try to boot from our flash drive.
