1) Download the ISO image for Off-line NT password Recovery.
2) Open the ISO image using ISOBuster and extract vmlinuz and initrd.gz file from it.
3) Put both of those files in your BCD\cds\corpmb\files\isolinux directory.
4) Edit your bootmsg.txt file to show it as an appropriate option.
5) Edit your isolinux.cfg file and add
append initrd=initrd.gz vga=1 ramdisk_size=128000
6) Recompile your Corporate Boot disk and it should work now.
