my $OEM$ folder is alongside the i386 folder, now one thing I did not do is put the winnt.sif file in the fix folder, i left it in the i386 folder, I created the iso and installed it on a virtual machine like i always do, and thats when the problem starts, is it because i left my winnt.sif file in the i386 folder? should i remove the winnt.sif from the i386 folder and move it to the fix folder then run the script again? Thats the only thing I can think of. If it helps, before I did anything with the hfslip I was able to make my unattend disk with no problem, so before doing the hfslip process, I made an exact backup of my c:\xpcd folder (so now i have 2 xpcd folders) I made an iso of both BEFORE trying the hfslip and both installed fine, then i did the hfslip on one of the xpcd's and it doesnt work (but I still have my original xpcd backup which i tested again and works fine) Sorry this is so long and I hope it helps
