The causes and methods of treatment the error boot disk read error occurred
If the appearance of the blue screen of death can not seriously to alarm, what can you say about those cases when you turn the computer on, a black screen appears with one or a few lines in English. Today we will try to deal with one of the most formidable and common errors disk read error occurred press ctrl+alt+del to restart. Translates it as «can’t read disk, press ctrl+alt+del and restart the computer.»
Causes of disk read error occurred may be different, but somehow they are either data corruption on disk, or with damage most magnetic surface of the disc, either with a train or other hardware components that is much rarer. Below you can find main methods of treatment of errors, but first let’s find out what may be its primary cause.
- Incorrect installation of a second operating system
- Installing old version of Windows on top of the new
- Manipulation of logical partitions in the presence of unstable sectors
- Drop working notebook (damage mechanics)
- System restore from an image on a filled interchange section
- Disabling the operating of the computer by the power button
- Deleting the boot entry antivirus
- Corruption of boot record virus
- Physical disk wear and it has many bad sectors
- Problems with the contacts, cable, controllers
- Faulty power supply
So, if you encounter an error disk read error occurred, first verify that no hardware problems. Go into your BIOS and see whether a disk at all. If not, check the connections. To be sure, you can try to connect the drive to a working computer. If the drive is not detected or the BIOS is not correctly recognized, the data on it has become a «mess» – carry the computer in service center, in this case it is better to trust experts.
Often the error disk read error occurred related to the partial or complete destruction of the MBR boot record, located in the zero sector of the disk and provides identification of the logical partitions. If the information is correct MBR, control is passed to section «system Reserved» and on through the chain system partition C. When it detects a mismatch error disk read error occurred or selеct Reboot and proper boot device. However, there are cases when the error disk read error occurred when damage to the boot file of the hidden partition «system Reserved».
Check the hidden partition
Boot from your Acronis Disk Director or similar program and make sure that the partition «system Reserved» is marked as active (checked). If the mark no, click on the tab, right-click and select «Mark as active».
At the same time make sure that required to boot the bootmgr file and Boot folder are in place. If one of these elements is not likely to cause errors in it.
File recovery hidden partition
To restore the boot files hidden partition you need a boot image from Windows 8.1. Then boot with it, click on «system», «Diagnostics», «advanced settings», «Command prompt».
To determine the drive letter, run the command notepad.exe. In the opened Notepad, select «File», «Open», «This computer» and see the letters sections. In our example, the hidden partition has the letter C, Windows partition the letter D, and the boot drive letter X.
Restore the boot files by running the command bcdboot D:/Windows. If the error was associated with damage to the boot files, the problem will be solved.
Check file system and restore the boot record
Error disk read error occurred can be caused by a corrupt filesystem. To analyze and fix disk errors in command prompt, the boot environment, type the following commands chkdsk C: /r and chkdsk C: /fand then repeat the same for the main partition with the system (section D).
If examination doesn’t reveal any problems, try to restore the boot record. To do this, at the command prompt, execute these commands:
Then do a search for operating systems and add them to the list on the boot menu:
Note: to restore the MBR records you can use a third-party program, for example, bootable Paragon Partition Manager. These same programs can be used to check for and fix errors on the hard disk if the chkdsk analysis did not produce results.
If the above methods do not help, you can try to reinstall the system, removing and main system and reserved partitions. Better yet, remove the drive, connect it to another computer and copying all the valuable information, fully formatted, and at the same time to check for errors. After that, clean the disk system is installed.
Alternatively, you can try the following method. From the user partition with Acronis or other similar program is separated Unallocated space and it installed copy of Windows. After that the boot menu should appear in two systems, one of which, maybe even both, would be quite the workers.
