Let's see, I have been running Windows XP *and* not one but TWO installations of Linux on my laptop for 6 months without any problems.  Suddenly, I have a problem with the display in *Windows* and nothing has changed with the Linux installation, and the display continues to function perfectly in Linux.  What is the answer?  Linux is causing the problem!  Oh, of course, how silly of me!  Yes, I'll just remove Linux from my computer right away, after all that is so convenient for me, and that will absolutely fix the problem that is happening in the other operating system, and not in Linux, that makes so much sense.  Why couldn't I see that?  There is a slight chance the problem could be with the boot loader, so I will try a different one, and even try Windows XP's own boot loader just to be a good sport.  But Linux is clashing with Windows?  Come on!  If Dell is going to outsouce tech support overseas, they have got to do a better job of at least making sure that the people who are doing it are competent.  You have got to realize that tech support is effectively PR as wel, and this experience has been extremely disappointing to say the least.  Unless this incident has a positive outcome, you had better believe that I will be discouraging everybody who I know from buying Dell from now on.  I am an IT manager and support a lot of Dells on the "front line" and I can't put up with a vendor that I can't trust to solve any real problems that come up that I can't handle.

"Sir I will request you to please install only one operating system
as Dell does not support Dual boot system so I will request you
to please change it back to original operating system . Because
both the operating system are clashing an that is the reason
we are facing error with the display ."
