Windows 7: Boot Manager Error 0xc00000e9

Windows 7 Professional x64
Boot Manager Error 0xc00000e9

Hey guys, I just received my new 1tb hdd for my laptop and I installed it and such and now im proceeding into installing Windows 7 Home Premium x64 on it. dice. I have the OEM serial code on the underside of the laptop and so I downloaded the official windows 7 iso since I don't have the original OEM disk that never came with the laptop.

i downloaded it from Malwaretips:
Official download links for Windows 7 SP1 ISO (32-bit and 64-bit)

Burned a bootable disk with it and when popping it into the laptop, It loads the files half way and they just stops! Then I get an error message in "Boot Manager" error 0xc00000e9'' info: An unexpected I/O error has occured.''

It also says it can be due to unplugging a hard drive or other essential hardware. Its weird though because I'm thinking its a DOA hdd but it shows up in BIOS.

That sounds like a problem with either the DVD? or the ISO itself.

Download a fresh ISO from here instead, and consider installing it from a USB flash drive instead, using this tool to create the bootable flash drive.

How did you burn the DVD? Use the tool Colin provided above or ImgBurn at 4x speed, or write to flash stick as also suggested.

Then follow these steps to get a perfect Clean Reinstall - Factory OEM Windows 7 .

If the install fails again, reboot into installer and at first installer screen Press Shift + F10 to open a Command Box, type:

SELECT DISK 0 (after confirming Windows 7 target HD #)
CREATE PARTITION PRIMARY SIZE=102400 (for 100gb partition, adjust as desired)

Next click Install Now, then Custom install to Clean Install Windows 7 to the partition you created. If it fails then report back at which step and the verbatim error message.

After install you can adjust partition size or Create new partitions for data, etc. in Disk Mgmt.You are creating the partition here for the purpose of marking it Active which overcomes certain install failures.

2. Press the F8 key.
3. When the Windows Advanced Options menu appears, use the ARROW keys to select Last Known Good Configuration (your most recent settings that worked), and then press ENTER.
4. If you are running other operating systems on your computer, use the ARROW keys to select Microsoft Windows XP, and then press ENTER.

We can also check if we can start the system in Safe Mode:

Meanwhile, please also check other USB devices on the computer, you can disconnect them and try to start the computer again. :)
