When i am installing windows xp3 in compaq presario cq40-301tu there displayed blue screen error....do u know the solution to get out of this error & continuing the installstions??

A) Installing same version of Windows, or a lesser version;

Enter BIOS Setup, and in Boot Options, set the first boot device to CDROM.

{Windows doesn't like being copied over by the same version, or a lesser version.
The above will make the computer boot up from the Windows XP sp3 disk you have}

B) If your computer came with a version of Win Vista, and you are trying to install WinXP over it, reply in a Comment.

For additional questions please post in a Comment
