A disk read error occurred: how to fix on a laptop via BIOS?

The appearance of the so-called blue screen of death inmany users cause horror and shock. And what about those situations when, instead of the usual loading on a black background, which is very symbolic, there is a message about the error reading data from the hard disk, generally its recognition, which is usually represented as a line A disk read error occurred. How to fix this error? Now we are in this and understand.

A disk read error occurred: how to fix. Causes and consequences

First, let's define the reasons that canto cause shibki of this kind. Suppose the message A disk read error occurred appears. Press ... How to fix this error, not every user knows.

Moreover, many do not even suspect that this isis generally. But it would be worth it. Apparently, with the operating system itself it is connected, as they say, insofar as. Most likely, the user himself caused irreparable damage to the OS. And that's why.

The simplest reason is the installation of a second systemto a local computer terminal (even on a virtual machine), installing an outdated version of Windows over a newer version, corrupting the boot sector due to incorrect shutdown, physical damage to the hard drive and plugging cables, conflicts between the system and antivirus software, etc. In general, the reasons for a headache suffice. But now we are going to talk about how to interpret the computer message A disk read error occurred. Press Ctrl Alt Del to restart. How to fix this situation? Simple enough. And do not be afraid. There is nothing particularly serious or terrible in this (of course, if the winchester has not "blown"). There are several solutions, which will now be presented.

The role of the BIOS in the process of restoring the system

First, let's define the BIOS. In fact, this piece is an integral software component of the motherboard, on which in most cases all other devices are mounted.

In other words, it is capable of recognizing all the "hardware" connected via loops, and changing the basic parameters supported by such devices during use.

Thus, to say that it is the BIOShelps to correct an error of this type, it is not necessary. After all, no one is immune from the fact that the message A disk read error occurred again appears. How can I fix the situation with BIOS settings?

First of all, you should make sureboot sequence. To do this, you need to call the BIOS settings before starting Windows. Usually this is done at the very beginning of the boot, after initialization, by pressing the "Del" key, sometimes - "F2", "F12", etc. It all depends on the computer system model and BIOS or developer version.

Now look at the priority of loading in the planprimary device. The system disk (usually drive "C") must be set first, unless another option is used. With him, too, there are problems. In this case, we mean the operating mode of the hard drive. Often incorrect switching of the IDE / SCSI modes for the SATA controller in the BIOS can "break" the whole system and cause only that the data not only will not be read, but the hard disk itself will not be detected by the system.

The secondary BIOS function issetting boot priorities. In this case, we have only the moment that the operating system itself should start from some specific media (and this can not always be the hard drive of the computer).

Black screen with message A disk read error occurred: how to fix via BIOS?

Now let's define the BIOS settings. First, go to the download settings and see if there is a system partition in the download. This can be the Boot Device Priority menu, Boot Sequence, and so on. Different developers can also use other commands to represent completely different BIOS versions. The essence of this does not change.

Checking the physical connection of hard drives

Now let's look at the situation when the line on the black screen appears again and again (A disk read error occurred). What to do?

If we have a stationary computer terminal,it is recommended to check the loops, which the hard drive is connected to the "motherboard". As you can see, you can expect that there will still be a problem with the appearance of the line A disk read error occurred. How to fix this situation on a laptop? Everything is much more complicated here. The fact is that all the "iron" components are non-removable, climb into the "laptop", tear off the seals, and even if it is under warranty, not everyone will want it. Here you will have to use software. It's a minimum.

Restoring the system

Before applying the cardinal methods, it is worth making sure that the system is generally workable, and reading data from the hard drive (at least from the system partition) is done without problems.

The system boots normally or does not load, there is no difference. First we use the boot in safe mode (F8 at Windows startup). Then go to the rollback function from the control point.

If this does not help, we boot from the installation or recovery disk, where exactly the point in time to which the system needs to be restored is selected. But even this does not always work.

Check the boot record

In most cases, problems with the hard driveinforms exactly the message A disk read error occurred. How can I fix the situation in terms of restoring the boot record and checking the disk? Use at least the simplest methods provided by the system itself, why not?

Here you should pay attention to somecommands executed by the system itself for restoring boot data, the registry, etc., as well as for special commands executed through the "Run" menu.

In our case, it's best not to use this menu, but the command line (it is called from the same "Run" menu by entering the cmd command). Now proceed to the teams themselves.

Special teams

Suppose that we have a problem in the formerrors with a string on a black screen. A disk read error occurred. How to fix? XP (Windows) to date, although it supports most of the commands, but still somewhat backward, even in terms of algorithms for their execution.

Nevertheless, when you call the command line that in the "ekspishke", that in the "seven", that in the "eight", that in the same "top ten" some teams work universally.

This applies to "First Boot Device" sequencing andSecond Boot Device. We install the primary priority in the BIOS CD / DVD with the installation or recovery disk in the drive and boot from it, then go to the console (in Windows XP - the "R" key).

Here you can use the recovery partitionbut it's better to go directly to the command line, and then enter the Bootrec / FixMbr, Bootrec / FixBoot commands one by one, if you want to check for multiple "operations" in the system partition at startup - Bootrec.exe / ScanOs, at most - to overwrite the entire boot area with a system disk check for errors and inconsistencies - Bootrec.exe / RebuildBcd. After this, there is no doubt that the system will not work.

What in the end?

If we sum up all of the above,that restoring the working capacity of Windows is not such a complicated matter even with the appearance of errors like A disk read error occurred. How to fix this, we have already figured out.

It should be noted separately that in this sectionutilities for checking the hard drive and fixing system errors like Victoria (the best for today) and a unique HDD recovery program for HDD Regenerator, which are able to "revive" hard drives even in the most critical situations with physical damage to the surface. But, as a rule, such cases are very rare, and special attention is not paid to them. But here in the program plan and in the settings, which in the future will be able to determine the behavior of the system, it is necessary to understand it carefully.
