Fix 1: Modify Bios Settings

I’ve listed this solution at the top because it is very effective to fix error code 0xc00000e9. By resetting BIOS or set it to its default configuration you can overcome this irritating error message.

  1. First of all, press the reboot button and when the logo screen appears then keep pressing F2, DEL or F10 Key (it depends on the system). This will open up the BIOS settings window.
  2. Choose “Load Optimal Defaults”
  3. Now, go to the PC’s HDD setting configuration present under the “Advanced” section. Now, you need to reconfigure the setting to either AHCI or IDE.
  4. After it, save the settings and then reboot your computer. Check for the error, it is hoped that after applying this solution properly you will never face this error.

NOTE: You should try both the options AHCI and IDE one by one. If AHCI did not work then apply IDE or IDE not work then go for AHCI.

Fix 2: Make Sure that your System’s SATA Cables are Connected Properly

If you are using a PC not a laptop then you should check the older SATA cables of your PC. Make sure it is in working condition and connected properly.

But, if you are using an older SATA cable OR connected a SATA II cable with a SATA III port and hard drive then the system will never provide a sufficient data transfer rate.

Windows Support Team:

If this is the case then the OS gets unable to communicate properly with the connected HDD and trigger this error code. Follow the below-given steps carefully;

  1. Shut down your computer and disconnect the power cable.
  2. Open the CPU case and find the hard drive, and the SATA port.
  3. Now, you need to replace the OLD cable with a NEWER one.

This step is only for those users who have experience in dealing with the internal hardware connectivity scenarios.
