Windows Vista based system requires numerous applications to perform a systematic booting. Corruption in any of these essential applications primarily results in unbootability of the system, further resulting in inaccessibility of the hard drive data. One such application is autochk.exe. This application is used to revert your system settings to their original state and perform backup whenever required. To overcome the after-effects of the autchk.exe application corruption, the user can perform 'startup repair' or 'CHKDSK' utilities. However, if the above measures fail to master the above issue, then you will need to reinstall Windows Vista operating system and restore the data from an updated backup. But, if the backup of the formatted data is unavailable or corrupted, then you will need to opt for an effective third-party data recovery.


To deeply analyze the above scenario, look at the below error message that appears at the startup of your Windows Vista system:


"error !! 0xc0190036 !! 5638/77767 (autochk.exe.mui)"


The above error message appears on the black screen. Since the boot process halts at the black screen, the data saved in the hard drive becomes inaccessible. In addition, the same error message appears each time you boot your system.



The root cause for the occurrence of the above error message is corruption of autochk.exe file.



To get rid of the above error message and to access the data saved on Windows Vista based hard drive, you will need to follow the below steps:

  1. Run CHKDSK to repair the corrupted file.

  2. In case CHKDSK fails, follow the below steps:

  • Purchase a new hard drive and try to save the mirror image of your hard drive.

  • Now, run CHKDSK command.

  • Delete the autochk.exe file and replace it with a new copy of Windows Vista.

  • Reboot your system.


In most cases, the above steps prove successful and your data becomes accessible. However, if both the above fall short in booting your system, then you will need to format the hard drive and restore the data from a valid backup. But, in case no backup is available, you will need to search for a commercial data recovery utility. Such Data Recovery Tools scan the hard drive using powerful scanning procedures and recover all lost data.
