The dual boot element is not an area I am an expert on I`m afraid but the info at the attached link may help you http://apcmag.com/ho...alled_first.htm if you need further assistance with this you would be better off starting a new thread on the subject.

Please Run the PCPitstop.com OverDrive Full Tests

Here's how:

You must use your Internet Explorer for this procedure. (doesn't work so well in Firefox or others). If your machine is running Vista or Windows 7, you must Select IE to “Run as Administrator”. After completing PCPitstop OverDrive you can close your IE browser and re-open it Normally so that you are no longer running as administrator.

Go to: http://www.pcpitstop...pit/default.asp
Click on "Free Computer Check-up" listed below PC Pitstop OverDrive
In the User Login - Click on "Sign up FREE!"
You'll need to submit a valid email address and create your own password, then click - Create Account(button)

Now enter your email address and password to Log in, Select - Scan this system Now!(button)
You will then be asked to download an ActiveX component and allow it to install.
It is safe and does not compromise your privacy.
Follow the on-screen prompts to install the ActiveX and to allow the Full Tests to be run on your machine.

The Full Tests take about 2 1/2 - 3 minutes on most machines.
When complete, a Results - Summary - Recommended Fixes will be displayed.

Please post the URL internet address, from your Results, back here into this Topic Thread so that we can review the configuration and present performance levels of your machine.

Note: During the graphics 2D and graphics 3D testing, your screen will display some rapidly moving objects.
If you are sensitive to visual flashing, it may cause dizziness. Therefore, look away from the screen during that portion of the testing.

After reviewing the results we will be more informed and may be able to provide better recommendations for you to work towards improving your machine's performance.

While PCPitstop does offer a variety of Paid Products, the PCPitstop OverDrive testing is FREE. Please ignore the references to Paid Products. We prefer to provide manual solution instructions that you can apply directly to your machine.

Thanks to rshaffer61 for the PCPitstop instructions

Hi Guys - were you able to find a solution for this issue? I am having the exact problem. The optiarc bd rom drive bc-5500s4 on my Sony Vaio VGN-NW270 is not playing BluRay discs anymore. This drive used to play everything (BD and DVDs) fine till August 2011. Something happened after that and when I tried playing BDs in Jan 2012, it won't recognize them (these same discs have worked on this drive previously). DVDs/CDs play and burn just fine as usual. Only BDs have stopped playing. I have tried almost everything mentioned in these posts, but nothing has worked. Please help!
