first off im new here, and would like to thank everyone for there work. great community here.

my LiveXP build work great by itself, hoping there is someone here who can help with SARDU, hope i didnt post in the wrong spot.

i built LiveXP_wim.iso tested fine.

renamed to livexp.iso
moved to SARDU iso folder
SARDU seen it, i didnt get no errors wen SARDU ran.

i booted off the USB drive, tryed all option everything worked, except LiveXP, winpe7 worked but not livexp

gave me an error:


windows could not start due to an error while booting from RAMDISK.
Windows failed to open the RAMDISK image.

File \I386\LIVEXP.WIM could not be loaded
The error code is 18
setup can not continue press any key to exit


i must have done something wrong????
