booting an iso file on the disk? possible?

Hi pituguli, welcome to NST.
Yes, its possible. Burn it to the CD with ImgBurn (an image burning software we know for sure works). To boot from it, you will need to change the booting order in the BIOS to have your CD/DVD first in the boot sequence instead of the HDD.
Hard disk or cd-rom? Can you describe more of the problems you're having?

And I don't think this belongs here since it isn't related to EasyBCD.
