Windows 10 An unexpected I/O error has occurred in BIOS screen

Hello,

I am getting this error message which briefly flashes the Windows loading screen. I have been able to confirm through the Windows RE Command Line and the dir command that the C: drive is accessible and likely is just suffering a bootup issue.

0xc00000e9-windows-error

I have tried:

  • Launching the repair process discussed in the error message three times, however each time it requires a restart and then returns to the same error message.
  • Changing the boot order to be hard drive first
  • Getting into safe mode: safe mode results in same error message
  • I have checked to make sure the BCD (bcdedit, Boot Configuration Data) is still intact

I plan to try (but would like additional comments on):

  • sfc /scannow; requires a restart and thus will likely result in the error message again
  • A memory scan
  • Swapping IDE cables/ports
  • Resetting the BIOS

I noticed others with similar issues around the web are dual-booting however, this machine is not setup in a dual-boot environment. Additionally, at one point this error message supposedly showed up before I started working on the computer

The instruction at 0xfbe2584d referenced memory at 0x00000008. The memory could not be read.

As previously stated, any additional suggestions or words of advice would be greatly appreciated.

Hi,

This error message: An unexpected I/O error has occurred. Status: ( 0Xc00000e9 ) is a hardware error pertaining to your system’s BIOS. Basically it is telling you that the computer is not able to reliably communicate with the hard drive.

Method 1:
Step 1:
I would suggest you to run the Automatic Repair Tool from Windows Recovery and check.

a) Boot from the disk, Once you get the welcome screen of installation with the option “Install now”
b) Click on Repair your computer

d) Now click on Troubleshoot
e) Lastly click on Automatic repair and follow the on screen instructions.

Step 2: I would suggest you to run sfc/scan and check.

The sfc /scannow command scans all protected system files and replaces incorrect versions with correct Microsoft versions. When the scan is complete, the System File Checker tool indicates whether integrity violations were found. If integrity violations are found, the System File Checker tool lets you fix the integrity violations.
