unattend.xml error

[agarabaghi]

So im using mysysprep x86 and was trying to prompt for computer name... I got it to pop up using %Please enter Computer Name% but it then gives me an error say something in the [specialize] pass failed, using Setup Shell component... this is where the %...% field is. Could that be messing up my file? Ive had good luck with %SerialNo%

also, there error starts a reboot loop as the machine can not proceed. Is there a way to get back into audit mode?

i booted into windows pe, browsed to the sysprep folder and delete the unattend.xml file. Replaced it with what i think might be a fixed one... but it still saying the system has reboot unexpectedly. Any way to get back into audit mode?
