I am getting the following BSOD on Windows 7, the computer is not even starting:

KERNEL_DATA_INPAGE_ERROR (Technical information: 0x0000007A)

I have tried Safe Mode, System Restore and Windows Repair, but none of them did work.

BSOD ScreenShot:


Anybody knows how to fix this?

  • Given the info here: docs.microsoft.com/en-us/windows-hardware/drivers/debugger/… and you have "0xC000009C, or STATUS_DEVICE_DATA_ERROR, typically indicates bad blocks (sectors) on the hard disk." Are you able to run a chkdsk /R – HelpingHand Jul 20 '19 at 21:36
  • i have access to a cmd on the windows repair screen, i will give it a try – yuribsl Jul 20 '19 at 22:38

From the screenshot provided, I can see the bug check code is: 0x0000007A.

A list of bug check codes can be found on this page: Bug Check Code Reference. In this case we have: KERNEL_DATA_INPAGE_ERROR.

I can also see from the screenshot the parameters of the bugcheck, the important one here being 0xC000009C. The documentation reveals this to mean:

0xC000009C, or STATUS_DEVICE_DATA_ERROR, typically indicates bad blocks (sectors) on the hard disk.

The first thing to try therefore would be to run chkdsk againt the drive. Running with /r will find physical disk errors in the file system and attempt to recover data from any affected disk sectors.

If you can therefore boot into a command prompt, run:

chkdsk /r

This should hopefully help.

TIP: Bug check codes and parameters sometimes point you in the right direction, but typically a dump file is required. A mini-dump may be useful, depending on the issue but it may take a complete memory dump.
