1- blestgrowl i think that u will not be able to setup xp from hard disk because you remove manual install and upgrade when you used nlite so you should use nlite again on a fresh non tweaked xp source then try to not remove "manual install and upgrade" from operating system options 2- another way u can copy this files below to your already nlited xp from the original source:"I'm not sure of that and if it works u will not be able to upgrade win98 you can just do new installation & u will get pop-up that tell u that" -copy SETUP.EXE to your nlited xp -copy WINNT32.EXE , WINNT32A.DLL , WINNT32U.DLL , WINNTBBA.DLL , WINNTBBU.DLL from source i386 folder to nlited xp i386 folder
