Hello , I have had some kind of xp iso file i burned it to a cd and i saved the MD5 checksum and then i lost the iso file but i have it on the cd anyway to bring this cd to a iso file that matches the original iso image before got lost thanks
The same (or a similar) software you used to burn the ISO can be used to read it back to HD (of course, unless you used the Windows feature). Examples for such software are ImgBurn, InfraRecorder, CDBurnerXP, Alcohol 120% FE.
