Windows 7 Startup Problem - Error code 0x490

[BetaTime]

Hey, I recently successfully installed Windows 7 on my laptop that also has Windows Vista. I was playing around with it for a few hours last night, shut off the computer and went to bed. I woke up, started it successfully and played around with it some more. Then, I shut it off again, and, a few hours later, turned it back on and, when I click on Windows 7, I am now receiving an error message telling me I did not install properly and to run a Repair with the install disc.

 

I did this and it said it found a problem and to "restart immediately" by clicking finished (it does not restart immediately, I have to click finish and then click restart). It also states that if the problem wasn't solved it would run the repair automatically. I restart it, it boots up and does the same thing. I ran the repair again and checked the detailed list of errors. It lists off a bunch of successful tests completed and then at the bottom it says:

 

"Boot manager generic failure 0x000000e

Root cause found:

-----------------------

Boot manager failed to find OS Loader

 

Repair action: File Repair

Result: Failed. Error Code = 0x490

Time taken : 7099 ms

 

Repair Action: Boot configuration data store repair

Result: Failed. Error code = 0x490

Time Taken: 171ms

 

Repair action: System Restore

Result: Completed Successfully..."

 

And that's it. I was getting the same error message when I had failed to install it correctly, but I fixed it (I think by resetting my BIOS). So, does anyone know how to fix this?

 

UPDATE:

When I select windows 7, it gives me instructions (which I followed, they are the steps I mentioned above) and at the bottom it says:

 

"Info: The boot selection failed because a required device is inaccessible"

 

I assume this means that it cannot access my partition for some reason...? If so, why not? Thanks!
