Windows 7: An unexpected I/O error has occured.

An unexpected I/O error has occured.

Hi, I have a huge problem with my laptop...

One hour ago, i got a bluescreen about something not working and that I should restart the PC. I did so, and got this error:

Windows Boot Manager

Windows has encounted a problem communicating with a device connected to your computer.

This error can be caused by unplugged a removable storage device such as an external USB drive while the drive is in use, or by faulty hardware such as a hard drive or CD-ROM drive that is failing. Make sure any removable is properly connected and then restart your computer.

If you continue to receive this error message, contact the hardware manufacturer.

Status: 0xc00000e9

Info: An unexpected I/O error has occurred.

ENTER=Continue ESC=Exit

If I press either Enter or Exit, the error appears again after a few seconds. My Notebook is an
Asus X70IO-TY021C 43,9 cm (17,3 Zoll) Notebook (Intel Core 2 Duo T6500 2.1GHz, 4GB RAM, 500GB HDD, Nvidia GeForce GT 120M, DVD +- DL RW, Vista Home Premium)

Can anyone help me please, I'm really kinda desperate...

from what i've been able to gleen from the web it's basicly your hard drive is either had it or needs the master boot record rewritten.

a link to guide from iseeuu forum member on how to redo your mbr should it require it.
MBR - Restore Windows 7 Master Boot Record

if you don't have a cd you may be able to press f8 after bios post and select 'repair computer' will be at the top if it's enabled but it is down to the manufacter to add it or not.

if your hdd has sacked it you could utilising another machine download a hdd tool from the manufacter website burn it to a disc as bootable and boot from disc at post, it will tell you if something is wrong.

if neither of these helps or isn't relevent let me know i'll think of something

I have my Win7 recovery disc put in, but it doesn't start from it, there's still just the same error again.

I'll try yout other thoughts too, thanks a lot.

Edit: I tried out MBR - Restore Windows 7 Master Boot Record

this hint, but after typing "list volume" i can't write anything anymore, there doesn't happen anything...

Enter the bios to make sure that the CD drive is first in your boot order. Also, the manufacturer of your drive probably has a disk utility with which you can check the drive. If not, Seagate Seatools are pretty good and can be used on any drive. There's a link to it and other HD utilities here:

Ok, I tried MBR - Restore Windows 7 Master Boot Record again, and at step 6, I got 3 lines, the first was my DVD device, the other ones my two partitions, but on C i had no label... what does that mean? The Fs for C was RAW, Type was partition, status Healthy, no info.

After taking step 7 and 8, i had the result:

Could not open the volume root directory: The parameter is incorrect.

From then on, it's the same as in the picture, just with the difference that instead of "Bootcode was successfully updated on all targeted volumes." I got "Bootcode was successfully updatedon at least one volume."

Does anybody know that problem?
