Does your laptop have a full O/S installed thats not working or have you format and now cant install with recovery disks?
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. We can try a few steps and check if it works:
Note: Disconnect External Devices (USB Flash Drives/ External Hard Drives etc)
Step 1: If Startup Repair is a preinstalled recovery option on your computer:1. Remove all floppy disks, CDs, and DVDs from your computer, and then restart your computer. Click the
Start button, click the arrow next to the Lock button, and then click
Restart.
2. Do one of the following:
a. If our computer has a single operating system installed, press and hold the
F8 key as computer reboots. We need to press
F8 before the Windows logo appears. If the Windows logo appears, we will need to try again by waiting until the Windows logon prompt appears, and then shutting down and restarting the computer.
b. If our computer has more than one operating system, use the arrow keys to highlight the operating system you want to repair, and then press and hold
F8.
3. On the
Advanced Boot Options screen, use the arrow keys to highlight Repair your computer, and then press
ENTER.
(NOTE: If Repair our computer is not listed as an option, then your computer does not include Startup Repair as a preinstalled recovery option.)4. Select a keyboard layout, and then click
next.
5. Select a user name and enter the password, and then click
OK.
6. On the
System Recovery Options menu, click
Startup Repair. Startup Repair might prompt you to make choices as it tries to fix the problem and, if necessary, it might restart your computer as it makes repairs.
