Currently, on CDDrive_X_Y.script enable "Run all programs from RAM",
so you get all your files inside boot.wim and accessable when booted from grub4dos/pxe etc.....

Reason behind:
since there is no real cd when booting from grub4dos etc. there is no accessable program files....
Aside:
If you do not like the idea of disabling CDDrive_X_Y.script due to some reasons...
There is a custom way:
-enable imdisk (Tweaks/Imdisk)
-write an application/batch etc. to search your .iso file (whatever name) and mount to Y:
Well since nobody truely needed such thing, nobody has written yet, maybe one day, maybe you, maybe ChrisR, maybe JFX
