It happened again!

Hey there,

I just had to run System Repair off the DVD to fix the same error. It scanned the system, used the last System Restore point, and restarted normally.

I understand that this temporarily fixes the problem (until it happens again), but I'd like to figure out what it is.

What causes an I/O Error, and what could make such an error show up only after I install Windows 7? It might be a coincidence, but I've never really believed in coincidence unless it's proven to me.

My father had to run the Startup Repair program from the DVD again this morning. This time, I was sure to double-check the log.

The registry was corrupt, and that was rectified with Startup Repair.

I think I figured it out - my father runs CCleaner religiously - I have a feeling that might have deleted an essential entry that CCleaner reported as being faulty/incorrect in some way.

I told him not to run CCleaner's registry cleaner function for a while and see if it has any more problems starting up.

Now for a related question: Can a corrupted registry cause the I/O error? Does the registry control I/O assignment?

Hello,

I'm having this exact same problem. Upon booting my computer I get a black screen with a "boot device not found please install an operating system on your hard disk" message. When attempting to install Windows 7 via disk it will load approximately halfway, and I'll get an error message that reads "Status: 0xc00000e9".

My CD/DVD drive seems to be working quite fine. Nothing is connected to the computer.

When using a Windows 7 recovery disc in the "System Recovery Options" box that pops up, I am unable to select an Operating System (doesn't show one). When selecting "select a system image backup" I get the same thing. No option.

Using the various "command line prompt" functions got me nowhere as well. I'm unable to use a system restore or restore previous backup.

I've bought a brand new hard-disk and get the same thing. No idea.

Anybody have any ideas? Any help would be greatly appreciated.
