The user may encounter unexpected scenarios when trying to access his system. In these, repeated errors are the main causes of irritation. The computer 0x00000e9 error is usually related to a bad hard disk (with corrupted system files) or due to invalid BIOS settings. The error 0x00000e9 appears during the Windows startup process on Windows os. The error code 0xc00000e9 comes in many forms. Because there are so many possible causes, it can be frustrating to discover the cause of the error. The accompanying text can tell you what the fundamental problem might be. For example, a message such as “An unexpected input / output error has occurred” may mean that your PC components, such as your hard drive, and have stopped communicating properly. A message such as “The system registry file is missing or corrupted” may indicate that some important operating system files are no longer working or can not be found.
- Corruption of your PC’s hard disk file system: Depending on the severity of the corruption, you may be able to recover all data from the hard disk using data recovery software and then reinstall the operating system without losing data.
- Loose / damaged connection between the motherboard of your PC and the hard disk drive: If the SATA cable connecting your hard disk to the motherboard detaches, an error code 0xc00000e9 may occur.
- Damaged registry files: Registry corruption caused by failure to install or update the operating system, shutting down your computer in the middle of an update, or a virus that could cause corruption.
- Hard Disk Failure: As your PC’s hard disk drive ages, sensitive moving parts begin to wear and break.
Method 1 – Run Disk Check
Running the disk checker tool is another useful troubleshooting method for correcting the Windows Startup Manager error 0xc00000e9 in Windows 7, as it will easily detect damaged areas of the hard drive.
- Insert the operating system installation disc.
- Restart the computer to boot from the disk.
- Choose your preferred language.
- Click “Repair Computer”
- Select the operating system that you want to repair if there are multiple operating systems installed on the hard disk.
- In the “System Recovery Options” menu, click “Open Command Prompt.”
- Type “chkdsk / f” in the prompt.
- The tool is now starting to scan your computer. After the process is complete, you must restart the computer to see if this resolves the error code 0xc00000e9.
Method 2 – Disconnect all external devices
One of the possible causes of error 0xc00000e9 is the faulty connection of external devices. It is therefore necessary to know which device is causing the problem. Turn off your computer and remove all external hard drives, printers, USB sticks, mouse, keyboard, etc. Turn on your computer to see if this solves the problem.
Method 3 – System Restore Should Correct Error 0xc00000e9
It may be necessary to restore your computer to an earlier date if one of the methods above would not solve the problem. Note that this method only works in case your computer gives you a delay before the error appears.
- Navigate to “Show advanced options”.
- Click “System Restore”.
- Choose a date on which your computer worked without any problems.
- Click the date.
The system restore should automatically start running. Although restoring the system does not interfere with your documents or personal files, it is a good idea to back them up before starting the process. Performing a system restore while your computer did not have the error code 0xc00000e9, should help you fix the current error and allow you to use your computer without problems.
Method 4 – Change BIOS Settings
Changing the BIOS system can be effective to resolve error code 0xc00000e9. You just need to set the default BIOS settings to see if it works or not.
- Start or restart your computer.
- Press the F2, DEL or F10 key (as appropriate) to access the BIOS settings.
- Select “Load optimal default values”.
- Access the configuration of your computer’s hard disk settings in the “Advanced” section. Set the parameter to AHCI or IDE.
- Save the settings before restarting your computer to see if this resolves the error or not.
To be sure, you can try the AHCI and IDE options. So, if the first option does not help you get rid of error 0xc00000e9; then next time select 2nd option.
Method 5 – Check your SATA cables
If this happens on a desktop computer, some users have discovered that using an older SATA cable, such as a SATA II cable with a SATA III port and a hard drive, may sometimes fail to provide a data transfer rate sufficient. In this situation, the operating system is unable to communicate with the hard drive, which causes this error.
- Turn off your PC.
- Open your case and locate the hard drive and the SATA port to which it is connected.
- Replace your cable with a newer one. If you have a SATA II cable, see if you can borrow a SATA III from a friend, just to see if it works.
- If it works, you know you just need to get a newer version of the SATA cable, which should be relatively cheap.
