One of the things that scares the Windows users the most is the blue color on their computer screen with some error code written on it. This blue screen (BSOD or blue screen of death) is shown only when Windows suffers really damaging errors that cannot be easily repaired preventing you from using your computer. Many of these errors are connected with the faulty hardware or some of the critical system files. But in some rare cases, you can fix these error relatively easily.
One of these BSOD errors that I recently encountered in Windows 10 is the File:\Boot\BCD Eroor with code 0x00000e9. This error further explains – “The problem can happen when a removable storage device is removed while it’s in use or is failing. Properly connecting any removable storage device and restarting your PC may fix this problem.”
The first thing you should do is check your hardware. The error 0x00000e9 occurs when your system storage disk (the disk on which Windows is installed) is not working properly – in other words, when Windows is not able to read or write files on this disk as expected. You should make sure that the data cables are connected properly between the storage disk and the motherboard. You should also check the power cables between the power supply unit (PSU) and the storage disk.
The I/O error could also occur of the power supply unit is faulty. It has become old, the internal components have worn out and now it is not supply the proper voltage or current to your hard disk or SSD. If your PSU is more than 3-4 years old, then you should buy a new power supply unit and replace the old PSU with the new one. When buying the new PSU, make sure you buy a PSU with same or higher wattage rating and that it provides same cable connections for the devices and the motherboard.
After making sure that all the hardware is in the working condition, you should boot your PC from the Windows 10 installation disk. To do this, insert the Windows 10 installation disk, power ON your PC and press F12 key repeatedly until you see the list of devices to boot from. Choose the Windows 10 installation media from this list (it could be Windows 10 DVD or USB media). Then press a key to proceed with booting from the Windows installation media.
When the setup screen appears, choose to Repair your computer and it will display you the recovery options. Under system recovery, select Advanced Options and then Command Prompt. When you are at the command prompt run these commands (press Enter after typing each of these lines):
After this choose to reboot into Windows 10 from the recovery options, or you can choose to turn off the PC and then proceed with normal reboot into Windows 10. This will hopefully fix the problem. But if this fails, then the culprit is obviously your system disk and you will have to buy a new hard disk or SSD for Windows installation.
