Windows 7: Boot selection required device is inaccessible 0xc0000225

Hi, I'm having this error for a while now.
this: 0xc0000225 Boot selection required device is inaccessible
What happened before this is just a forced shut down because the computer is lagging. After that, this error in now showing up.
I have a recovery disk but I can't manage to open it up, cause I dont know this stuffs



Please help me
What should I do???

Boot up using the Startup disk CD or Windows 7 DVD. (not the OEM manufacturer's Recovery Disk) If you have a Netbook, you will need a CD/DVD drive.
Make sure no USB drives are plugged in.

Try a Strartup Repair:
Startup Repair
Note: You may need to do startup repair 3 to 4 times.
Startup Repair - Run 3 Separate Times

If you have not made your Startup Repair
System Repair Disc - Create
Do you have a mate with Windows 7 & CD/DVD RW Drive, how could burn one off.

I finished the repair once but it's still the same,
Should i re-run it?

Ok, I have an idea. I have the laptop's recovery disc(the one that is almost 10gb).
I've burned it to 3 dvd's and copy all the files inside each dvd to my external hard drive.(I separated them to 3 folders).
Now, I dont have the 3 dvds, but I have the files. How can I burn them back to the dvds which can be booted?
