I would like to edit the boot.ini file to disable DEP and change other settings. The web guide says I can do it, but my version (2.1) have these greyed out.
First off, EasBCD doesn't work with XP and the boot.ini file. It works with the BCD file that was introduced with Windows Vista and beyond. You can add an entry for XP, but you cant use EasyBCd to modify it in any way other than add an entry for it.
