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 this 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.

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 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.

When I try to boot my laptop I get a boot failure message: "Default Boot Device Missing or Boot Failed". Most often, this error can occur after a PC emergency shutdown. Our short overview of solutions will allow you to quickly deal with the problem and restore the machine’s functionality.

Boot failure “Default Boot Device Missing or Boot Failed”

This error mainly appears on Lenovo and Acer models and indicates that the boot settings have gone wrong. First of all, check whether the BIOS default is to boot from the HDD. This is checked in the “Boot Device Priority” option. It is possible that it won’t let you into the BIOS the first time, try logging in several times. The optimal solution would be to remove the battery on the reset board - it's a small flat battery. In other cases, the reason lies in the use of the base UEFI system instead of the standard one in the BIOS. We need to switch gears.

1. Reboot the computer.
2. After turning it on, press the “F2” button.
3. We get into Bios.
4. Go to the last tab “Boot”
5. First line "Boot Mode" switch to "Legacy", A "Boot Priority" on LegacyFirst.
6. Next, go to the Exit tab, where we confirm the “Load Default Settings” mode via “Yes”.
7. We exit the Bios, saving the changes in “Exit Saving Changes”.

If everything is done correctly, it should start. If it still doesn’t start, then try inserting the WIndows installation image, specifying to boot from the media and enter Win startup recovery mode there.

What to do if Bios does not start?

If the BIOS does not load at all, then you should use third-party software. This utility will help us here Rufus. This application will allow you to restore boot files so that we can start the operating system normally on a laptop with a malfunction. You need to download Rufus to a third-party computer, stock up on a flash drive and download Bios for your model.

The procedure is as follows.

A separate point is flashing your BIOS in Crisis Recovery Mode. This process is quite complicated and the serial number may fall off, which is related to the warranty; it is better to let specialists do this.

Problem Default Boot Device Missing or Boot Failed can only be solved in Bios, I hope you understand what to do there. After the fix, it will not prevent the operating system from loading. Finally, a little video on how to properly configure the download:

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 using the HDD Regenerator program. No matter how good it is, it is simply not able to eliminate absolutely all problems with the hard drive.

Question: Setting: "Start booting from USB device"

Answer: a way to install windows from another PC.
In short, the method is to unpack Windows from the win file directly to the HDD, then add the yf ytuj bootloader and the installation will continue, that is, we’ll skip the moment with the flash drive.

Added after 46 minutes
via the command line we prepare the disk for installation

1)diskpart
2) list disk
3) select disk X (where X is the disk number from the list obtained by executing the previous command) read here how to find out the disk number
4) clean
5) create partition primary
6) select partition 1
7) active
8) format quick fs=ntfs label=”Win7-ATLANT-PC.RU”
9) assign letter X
10) exit
Don't close the command line

Now we will extract the desired OS from the INSTALL.WIM file to our disk.
The operation will be carried out using the dism command
dism /apply-image /imagefile:F:\sources\install.wim /applydir:X:\ /index:1
For ease of operation, I took a separate application dism.exe
unpack this archive to drive C:\
The Start.cmd file changes the command in it and launches it.
unpacking install.wim to the created partition
to find out what index is for your desired OS, use the command
Imagex.exe /info F:\Sources\install.wim
We see that files have been extracted to our disk.

Question: When installing from a flash drive it stops at "start booting from usb device"

Answer: dzu, Everything worked out, thank you very much)

Question: When installing an OS from a flash drive, the message “Start booting from usb device...” is displayed on the screen many times in a row.

Answer: The functionality of ultraiso is quite enough for me to create a bootable flash drive. I solved the problem by recording another image. The topic can be closed

Question: Start booting from usb device and so on endlessly

Answer:

Message from dezraid

Is it because the BIOS is old or what? How to fix it?

Try this (the OS downloaded to the USB flash drive from Microsoft installed without problems)

Question: Window 10 No bootable device

Answer: I checked the hard drive using Victoria, no bad sectors were found, a little more than 100 sectors with a response of 200ms, but S.M.A.R.T. in poor condition. Blue screen error "MEMORY_MANAGEMENT". In the Windows log, exactly before a critical system stop, 3 file filters “npsvctrig”, “FileCrypt”, “aswSnx” and “aswSP” are loaded.

Question: Windows 10 error 13 disk pdo:\device\00000026

cmd: chkdsk c: /f/r
reboot, then the check takes a long time, hangs for about 15 minutes at 14 percent and ends abruptly
As a result, the log shows error 13 again
Launched by Victoria....

Answer: Updating the BIOS didn't help.

Question: The /MAX key in the START command does not work (the window does not maximize)

It starts, but does not deploy. Win+Up works in principle. CHADNT?
Or is it a feature of the application itself?

Upd: a short search led me to this

But this, in my opinion, is absolutely fierce Jediism...
The idea is to give git-bash.exe the -w max or --window=max argument, i.e.:

also didn’t lead to anything: just a window quickly flashes and that’s it.

Of course, there was an idea to take and rip out that line that is passed to the system() function, which was advised by that Indian friend from the overflowing stack, but personally, such attempts almost immediately caused a brain overload for me, because I am extremely familiar with this CMD/BAT of yours.
So I sincerely ask for help from local gurus! Thanks in advance!

Answer: Well, in general, I gathered my strength and did this:

This is of course not a pure bat, but at least it starts from there.
Well, for some reason he really swears that he can’t find the icon in the specified path, but that’s minor stuff.
