Assuming there is no problem with the machine, I would suggest that you have failed to burn a bootable CD, for some reason.
You say .... "extracted all files to a cd"
There is no extraction required .... You simply burn the .iso image
to a CD using something like ImgBurn ... or even Nero can do it, also. The CD created will be bootable.
You may need to revise your technique here, and I include some links below that may help with this:
ImgBurn - the program: http://www.imgburn.com/
Download and install the program. Launch the application and choose the option to "Write image file to disc".
OR ... perhaps you prefer this way ...
1. Browse to the ISO-file you want to burn
2. Select the ISO file and right-mouse-click now
3. Choose "Burn using ImgBurn"
How to do it with Nero:http://www.bay-wolf.com/burnimage.htm
Edit: forgot to say ...
Download Darik's Boot and Nuke 1.0.7 * for CD and DVD media.
This is the file you need to download for burning to a CD: dban-1.0.7_i386.isohttp://sourceforge.net/projects/dban/files...86.iso/download
