Hi Bedis, welcome to NST.
Are you trying to use EasyBCD to control your boot on XP ?
EasyBCD is a GUI app for managing the BCD.
The BCD is a feature introduced with Vista and continued into W7. It does not exist in XP.
It is possible to run EasyBCD on XP, if XP is one system in a multi-boot with Vista or W7, because the BCD will exist on Vista or W7
It is possible to copy the Vista/W7 boot files onto XP and use them to control the XP boot, but you must own a valid licence for one of those systems.
